- Travel into the circulatory system to see how blood pressure helps deliver oxygen and nutrients to your body’s tissues.
--
If you lined up all the blood vessels in your body, they’d be 60 thousand miles long. And every day, they carry the equivalent of over two thousand gallons of blood to the body’s tissues. What effect does this pressure have on the walls of the blood vessels? Wilfred Manzano gives the facts on blood pressure.

Samuel Ramos If you're into that kind of thing, then that's fine by me. :)
Samuel Ramos I can't see anywhere in the video where there is a need to use any gods to explain the workings of the arteries.
My whole body feels weird after watching this video, it's like my blood vessels know we're talking about them 😳
Man tell me about it, I'm boutta stick a wire through any artery I feel suspect!
I just found out I have high blood pressure and I have to wait a whole week to see a doctor about it. I Hope my arteries can last that long. 💀
@@Looklikeboy so did they or nah
The fact that he didn't respond might answer that question.
That's a hard nah
That is probably Angina
I battle high BP, had a heart attack at 42 and have a stent in the artery on the right side of my heart.
People say a bad heart attack feels like an elephant sitting on your chest; it's an apt description. It's by far THE most pain I've ever experienced. So much pain, in fact, that for the first hour I could do nothing but literally writhe in agony on my bed, begging for it to stop. It was a further 2 hours before I could drive myself to the ER.
When my BP gets too high, I can literally see it. The edges of my vision darken with each heartbeat -- sort of like the beginning of tunnel vision, but the tunnel never closes fully.
Plus when it gets that high, I can also feel the extra pressure in my eyeballs with each beat.
Gracias p ser tan explicito en tu descripcion d dolor ataque corazon!!!! Los medicos no educan. Es impprtante saber pa tomar conciencia y cuidar. Mi padre murio d muerte subita ; ataque corazon. Solo. Sin atencion medica. Tenia 59 a. Tambien sufro d hipertension. He tenido 22 / 12 o mas pero no me doy cuenta. P eso le dicen " asesino silencioso " 🖑🇺🇾
I woke up this Morning to 148/124. Has a stress test and a eco this week and he said my heart was great. Three nights ago at 3 am my bp was 231/127. Five nitros later it came down enough not to die. Best wishes to you.
Wow that’s scary
I brought down my blood pressure by taking most carbs out of my diet. I follow medical doctor Ken Berry on youtube. czcams.com/users/KenDBerryMDsearch?query=blood%20pressure
@@gilbertguindon2385 thank you for the advice. At this point I’ll try anything. 👍
A combination of blood pressure, poor diet and exercise, hereditary growth hormones, and excessive walking/hiking left me with varicose veins in my legs, resulting in often swollen, purple ankles since the veins are stretched so wide the pressure from the heart can't push it back up all of the time. I feel like this is the kind of thing that should be taught more in schools, especially since teenagers and kids often go for cheap, sugary/salty/fatty foods.
Try to do more cardio and eating more vegetables with fruits and proper meat then.
I'm doing calisthenics, you know skin the cat, one arm pullup etc.. And I had some my veins more pumped up, than it would be cool. When I started to do more cardio, they seem more relaxed (and also my overall perfomance got better), so running, cycling, swimming, maybe it could help your varicose.
I don't know about everyone else, but I was taught all these things in public school and we even had to do class presentations about it. It was my choice to not really care about them as a young teen because no one told me I was learning about my own body because it's important, instead of just because I had to know temporarily only to pass a test at the end. People often say "School is important", and I believe the same, but not telling teens *why* it's important will result in many people forgetting they were taught these things in school, or even thinking that "school is useless".

Literally me lol. I've been having higher than normal blood pressure after puberty, that's over 12 years now. Nothing happened yet but I do sometimes get really bad headaches when the blood pressure gets high.
@Gagarfield and then proceed to measure your BP on a bp monitor raising your bp even higher with the blood pressure inducing bzzzzzzz sound as it pumps up your arteries.
@@Edzter Not everyone is the same, the big pharma idealisation of the perfect 120/80 bp to fit everyone is an oxymoron. Relax and just be mindful of your wellbeing, eat properly, excercise and dont worry :)
Wow!! This scares me :( being able to see the process of a clogged artery and just the thought of that happening within my body is terrifying.
I don't want to scare you but it's kinda hypochondria.

High blood sugar resulting from insulin resistance also damages the artery lining and is probably more prevalent than high BP, especially in older people.

Two months ago my bp was around 135/82-90, then I got a gym membership and I go 5 days a week around an hour or two a day and its around 116/59-64 now. Im 30 and feeling good. Changed my diet as well....
great job 👍
Rifat Hossain Thanks!
Well done!
There this one time I didn't notice I was driving to work with my bp was around 180......the world was kinda spinning at that time and the doc tell me I could had a stroke or something.
Diet is the key
"Your arteries are well suited for the challenge..."
Average American diet: "Imma bout to end this man's whole career..."
Tbf, the fact that the human body can even allow itself to get to the size that the obese American gets to, in of itself is very impressive. But by God, that is most definitively a challenge.
bahahaha
It's called SAD (Standard American Diet) ... and it's sad
communism loves blood so much they want it on the outside
This comment is SUPER UNDERRATED!!!
One thing many aren't aware of that raises BP is straining on the toilet. If you're constipated or just finding it difficult to make a bowel movement happen, don't spend an endless effort to try to push it out. Typically people will hold their breath while straining and this increase BP in your head dramatically. If done often enough, you can cause serious damage to your arterial walls. Same for lifting weights at the gym while holding your breath too often.
Ah... I do this everyday for no reason.
I noticed I get faint or belly aches after the restroom.
Now I know. And knowing is making me scared. Lol
Thank you for sharing this! My mom tends to constipate a lot and so she ends up doing this most of the time. I really appreciate this information!
Always breathe when pooping!
That’s how hemorrhoids are created! Thanks for posting.
Straining cause higher blood pressure but once relaxed the blood pressure should be less so this is actually a good thing, this is one of the reasons why exercise is good for blood pressure.
Now I understand I’m in danger, my mom gotta stint. Dad hypertension. Granddad stroke. When I eat and sleep as a truck driver, I sometimes wake up and my whole body is pounding. Thank you for this
Hope you turn out well...
Hey high blood pressure runs in my family too.

@@hemanrocks9249 exactly
Medical degree: am I a joke to you?
These videos are extremely simplified. The problem wasnt your teacher, but you who didnt give a fk
@@MLarios97 - A good teacher can instill curiosity and make a subject otherwise uninteresting to someone, interesting. Once something becomes interesting, pursuing more information about it, resulting in accumulation of knowledge and “successful” learning, breeds more learning and more success. Ergo, the value of a good teacher or, as reflected in this video, a simplified, but interesting introduction to a subject, can inspire someone not naturally curious about a subject. Imagine unleashing all the brainpower of superficially uninterested students…. Good teachers are the most valuable asset in society.
This looks suspiciously like a Kurz Geasagt video...
I had the exact same feeling! Especially the way they drew the vessels, blood and nutrients molecules.
Indeed *****
Indy awesome When I saw the thumbnail in my subscriptions feed I thought I was clicking on a kurzgesagt video, then I heard the voice and was really surprised.
Indy awesome yeah
Indy awesome but it is by FOXADHD, and there's no scientific animal dick in it. But this video looks a lot like Kurzgeasagt's. So the guy works in two channel, may be?

It is said over 50% of people my age have the so called hyper tension, what does that mean? Maybe they are normal and are doctors need to throw away the book and learn new things.
I wish you would have discussed low blood pressure too. I know that high blood pressure is much more common nowadays, but I have low blood pressure that sometimes causes orthostatic intolerance and POTS symptoms in the short-term, and I do wonder how that could affect me in the long term too.
I was going to make the same comment because I also suffer from low blood pressure, thank you.
Me too, i was waiting for the explanation of what causes low blood pressure because i suffer from it a lot and i don't know much about it
Me too
Same. I also suffer from low blood pressure and it sucks, makes you feel very weak. It's really hard to find information about it online.
Same!
I was sleeping for past 3 days because of that and then youtube recommended me this video
Last statement meant a lot...n my heart beats started smoothly
Omg your explanation and animation are both immaculate. What a Great work. THANK YOU
am i the only one who cringed through the whole video thinking that it would happen to you?
my wife has hypertension and this made me want to call her to make sure she's ok even though i saw her like three hours ago ;;^_^
nope
I had high blood pressure for a while when i was at the hospital. I don't wanna make yall cringe so i aint gonna say for what ;-;
Basically i felt really nauseous and tired but overall i was okay
So um
Just get yourself something to help with sickness when you're doing something that will probably do this
If u take care of ur diet and get regular check ups/lipid profile tests, you are good to go.!

That's if you have chronic hypertension,,, which you don't have,,,

Love this!!! Beautifully illustrated and extremely well narrated. Applause.
Such a simple and compact video....loved it...
I was eating salty foods while watching this.
Unprocessed salt doesn't cause this effect because it's balanced with other trace minerals which normalize blood pressure. Sodium Chloride (aka table salt) is what you don't want to load up on, and it's what most processed foods have, sans the trace minerals. Pink Himalayan Salt, Sea salt, Redmond's Real salt, Kosher Salt, etc. Basically any NATURAL rock salt will have 60-80+ trace minerals that you need in balanced amounts for a healthy electrolyte balance and blood pressure.
Salt is actually necessary for heart to work properly. Too much salt is another thing.
Same Lol
@@batra204 That and it makes you hold onto fluids, which is good unless you have to much.
And now, you will probably not eat any for the rest of the day.
This blew my mind.
I remember how I was mentally tired and stressed and all I wanted is a salty diet.
Now, when order came into my life, I no longer crave salty snacks.
What a fascinating system we have, that's amazing.
I can prescribe you to Doctor Oseiwe who cured me from Diabetes and Asthma, you can also get in touch with him on CZcams channel Doctor Oseiwe, if you need help and be cured completely🇱🇷❣️.
Thank you you for the warm sharing ❤️
This is a great layman’s guide to understanding BP, clogging, and how we fix it. Kuddos!
This answered a lot of my questions...like when people check blood pressure why are there 2 different numbers? Great video- I owe you :)
learned about heart attack and stroke as well. thanks
Years ago, I stopped sprinkling sea salt on my food and increased my water intake because I did have a bit of water weight, I looked a bit swollen from my face, nothing major or concerning. I wish I wouldn't have. I started to be thirsty all the time, urinating every 15-30 min, unless I stopped drinking water but then I'd be so thirsty, extremely tired, my BP was high, I had palpitations all day, couldn't even walk without my heart being at 120+. I was severely dehydrating my body. At first I didn't even made a connection, I spend 2 years being miserable, not knowing what was wrong with me, then after those years "researching" on my own, I realized I was experiencing symptoms of water intoxication. The day I started sprinkling salt again, all the symptoms went away, I felt awful because I never made a connection or realized. I'm fortunate to know now how important sodium is for our body. Low sodium can raise your BP and it can lead to strokes too, salt is not bad we just need to balance it with our water intake.
Sending blessings to anyone the algorithm has sent this way 🙏🛐

My grandfather had heart problems throughout his entire life, and when he passed away recently, they said he had so many stents that they couldn’t fit any more. My dad has a few stents too, so I hope that it will not develop for me!
Thank you for the informative video! So by staying healthy and exercising, will it keep the blood pressure at a normal level and prevent it from happening? And if my dad were to start exercising and staying healthy, could the plaque be removed naturally without putting more stents in? I’m not sure if anyone will answer this due to the age of the video, but if you do, thank you!
Yes

Damn, I have high blood pressure, love salty foods & take daily medication for hypertension but not one doctor has explained the effects or consequences so well as this short video. Thank you for this video.
Medication don't treat the cause, just the symptom to stay healthy you have to thin your blood with healthy vegetable garlic and onion should be also included
Yeah, definitely take it seriously. My father had the same issues with chronic hypertension, needed to avoid salt at all costs. He still ended up dying of a heart attack at an early age, even while restricting salt. That said, I honestly, I don't think salt should always be blamed. I eat more salt than a family of 5, literally pour it onto stuff, and have healthy blood pressure. The real difference I think is my father ate a bunch of junk food and was very overweight (lots of cakes and things like that). People like to demonize salt but there's plenty of research out there contradicting the (over) demonization of salt.
*Everyone is different, some people are very sensitive to salt and some require a lot more than others- experiment with new diets and see what happens.
Sugar & carbohydrates is the real deal. Try include vitamin e & fishoil.
My step dad has HBP regularly. He is 53 yrs and overweight. I really worry about him, every time the HBP occurs, man I always end up in tears and pain just see him struggling. Whatever it is, i wish my dad for the best. 🙏
