Ever wonder what causes the thump-thump sound of your heartbeat?
It’s all to do with the valves. The sound of your heart beating can be attributed to your valves closing, and always in specific pairs.
Separating the atria from the ventricles are the tricuspid and bicuspid valves.The pulmonary valve and the aortic valve ensure that deoxygenated and oxygenated blood, respectively, leave the heart entirely without any backflow. This beautiful system sees that both the tricuspid and bicuspid valve are closed when the ventricles, both left and right, contract - this contraction forces blood out of the heart, through the pulmonary arteries and aorta.
The first thump that you can feel is the sound of the tricuspid and bicuspid valves closing simultaneously.
So during systole (the first half of your heartbeat) the tricuspid and bicuspid valves are closed, but the pulmonary and aortic valves are open. Once the ventricles relax, the pulmonary and aortic valves close, causing the second thump of a heartbeat. When the pulmonary and aortic valves are closed, the tricuspid and bicuspid valves automatically open.
During diastole, blood (both oxygenated and deoxygenated) fills into the heart.
The average heart rate for a young adult varies, depending on age, physical size, genetics, and activity. It is usually in the range of 60 - 100 heartbeats per minute. The fitter you are, the lower your resting heart rate is likely to be. An athlete may have a resting heart rate closer to 40 beats a minute.
After each heartbeat, a pressure wave passes along your arteries, which causes your arterial walls to bulge, and then contract. These pulses, as they are called, can be felt at various points throughout your body. A strong pulse can be felt at the top of your neck.
Although you cannot quantitatively measure the force of your pulse, you can do so for the overall force exerted against arterial walls by your blood - this is called blood pressure.
Usually your blood pressure is given as two numbers. These numbers represent the forces exerted during systole and diastole, known as systolic pressure and diastolic pressure. The systolic pressure is quoted before the diastolic.

SAVED MY LIFE❤❤❤❤❤❤❤❤❤❤❤
So glad 🤗❤️

Thank You Mam for clearing my doubt...
Most welcome!
@@fuseschool 😀😁😃
Thank you
No problem!
Can we have a video about how the respiratory system works with the cardiovascular system please?
If you have video you post it on CZcams
Sylvia Turnbull of course kisne mana nahi kiya hai kya
Yes please
Respiratory System video: czcams.com/video/fQsgZloXNPY/video.html
@@ajwanisiddhant are u pakistan
Thanks this helped
Glad it helped!
Very nice.. This really help about Biology and physics..
Glad it helps 🙂
It not support knowledge at all …. Sorry it is not in my respect
Great vids
Nice and right notice
Very helpful video
Glad you think so!
Great for basics. thank you
No worries!
i wasnot under stand but you the best teacher thanks for good

I sometimes listen to my heartbeat when it goes fast and slow
I’m loving the lofi hip hop music in the background
Just heard it too
My heart rate is 56 and pressure is 120/80 uuhg is that normal
Which software do yo use
We use After Effects.
I can't find the blood pressure video. Can someone help, please?
Hi Somayah! Sorry about that, we had to remake the video, so unfortunately it is not currently on CZcams.
Good video .I think it helps me learning.
Glad to hear that!
I am pregnant and my heartbeat has remained 140/80 for about 4 months. Is this normal?
Plus some moments of palpitations
I hope everything worked out okay.
Who else is here because the teacher gave this link?
:) heRe.
Cannot understand
Are you from Pakistan 😀 coz your lectures are according to my book😀
The UK 🙂 But glad to hear that the lectures are aligned!
Nice video, but didn't mention the heart beat is due to minerals within and without the heart from creating the pulse...
..
هههههههههههههههههههههههههههههههههه
Heart rate.
NOOOOOOOOOOOOOO I DONT CARE WHAT THE HEART SOUNDS LIKE
...
noice, but I have better things to do
