- Hematopoiesis is the process of creating new blood cells in the body. All blood cells start off as hematopoietic stem cells, and then specialize (differentiate) into myeloid cells (erythrocytes, megakaryocytes, monocytes, neutrophils, basophils, or eosinophils) or lymphoid cells (T-lymphocytes and B-lymphocytes).

Red marrow is found in the epiphysis (ends of bone) not in the medullary cavity (center). The medullary cavity contains the yellow marrow.
very true ....surgeon here
You are right but isn’t the case different in enfants and children whose bone haven’t matured yet as in you can find red marrow in the medullary cavity of children and enfants. Please correct me if I’m wrong.
In adult,In central axial bones the medullary cavity has also red bone marrow and in proximal bone ends of humerus and femur.In child red bone marrow is present everywhere.In child 100 percent bone marrow is red.
You are correct AISSA
in yellow bone marrow in diaphysis of weight bearing bones, stem cells are present but in lower quantity than the red bone marrow in epiphysis, atleast thats what i read at my level of education. A pre med student here
These genius people that corrects her ... Am I the only one that doesn't know anything before I watched this video?
wow, well done! the only place that was able to breakdown the word hematopoetic so thoroughly and perfectly! this was great! i feel like ya'll should go into turning your teaching videos into mini cartoon short films that dumbs it down even further for much younger group of folks. this is better then taking classes at any university!
One of the most simplest yet amazing videos out there.
you didn't even talk about hematopoiesis, you just named cells. I wanna know that process.
@@AITv-d6f yea but I'm pretty sure she wanted to know the process of how the a stem cell becomes an erythrocyte and then to erythrocyte..
@MrRelativity_ If you don't like it, then just simply leave the page!
Life Saver. Thank you so much for this video!!

Wow, she is really good at using that program to draw what she is talking about. She seems to have a lot of control in the program. What program is that? Does anyone know?

I love you i love you, I FREAKING LIVE YOU. I AM GOING TO PASS MY IMMUNO EXAM BECAUSE OF YOU 😭😭

Excellent explanation
thank you, thank you, thank you
It was really helpful
That was a good summary...
thank you :)
Great work👍
Thanks💕
Thank you so much
please tell nutritional factors involved in hematopoiesis?
Thanks🧡
As a holistic overview this is okay but the lack of detail is frustrating.
Thank you so much for helping us god bless you 😊
Thanks sir
Monocytes, do not have always a kidney shaped nucleous they are more like irregular and with no defined form. The cell that has a kidney shaped nucleous is called metamyelocyte
What colour would you choose for the bacterium?
love you...
You are awesome
dats cool
I loved the lecture.
But I need a detailed one😔😔
should've let a Clinical Laboratory Scientist / Medical Technologist give the lesson
Is this on the Khan Academy website? Can't seem to find it
mam.. where are u from...? but I like u in the way of approach the topics and clarify easily.. ❤❤❤ tq mam
Funny "....in science we never use plain and ordinary names..."
I want hemopoiesis process
"wait no, i like the color pink, let's use a color i don't like" hahahhah!
what a voice. just love the voice. I am from Bangladesh. take love
No detail of haematopoisis from embryonic till adulthood. And no mention of sites of haematopoeisis. Neither the main progenitors.??
The RBCs look more like cough drops than dumbells
'In science we never use the plain and ordinary name.' 🤔
Wow she didn't even explain hematopoeisis properly
why she did not give granunules to neutrophil? 8:00
Sir plz mere ko erytropoisis ki ppt banani hai to muje plz idea do ichha vala jisse me achha presentation kar saku
You didn't mention NK Cells :(
It wasn't detailed enough..just basics wouldn't help
💖💖
Hello Friends
anybody who can tell me about MOH,DOH and DHA Exams ??? And about Important Stuffs that can help me in exam please guide
Good lecture but kinda lacks details!
Are platelets not Lyphoids?
NK cells?
Leukocytes?
you did not talk about the basic process
Not trying to be rude but the video is called hematopoiesis and all that was talked was talked was the final stages of the blood cells. Feels like a clickbait!
😘
is "pluripotential stem cells" just another name for hematopoietic stem cells????? my book says pluripotential stem cells or also known as "hemocytoblasts." But doesn't mention the name hematopoietic as you had written on here.
sunny kem
pluripotent hematopoietic stem cell or haemocytoblast
some problems with the spell
Question: Eosinophils are red because the dye used to identify them (eosin) is brick red??? Am I wrong here?
They are "eosin loving" or by other words, the name is made by their characteristic ability to be stained by acidic dyes, one of which and the most popular is eosin.
aren't monocytes lymphoid cells and not myeloid
This has nothing to do with hematologic system diseases though
Why the centre of red blood cell is so thin
Good question
did she actually told scary Greek word hematopoiesis lol
10 minutes of nothing...
what is this female voice.. what happened to khan I'm pissed
You haven't detail the process of haemopoiesis! You are talking too much and and can't understand your lecture.
please stop saying the words you're writing over and over as you write them "myeloid, mmyyyeellooiiddd group, myeloid" its incredibly annoying...
boooon meŕrro
haeamato
your slang is😁😁😁
