Hematopoiesis | Hematologic System Diseases | NCLEX-RN | Khan Academy

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.

[@somerandomperson2112]

very true ....surgeon here

[@Aissa_gilly975]

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.

[@muhammadowais7171]

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.

[@jananishree4468]

You are correct AISSA

[@yuki-7224]

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

[@PBTKaizen]

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!

[@ningsiheinstein5251]

These genius people that corrects her ... Am I the only one that doesn't know anything before I watched this video?

[@sarahbabik8285]

you didn't even talk about hematopoiesis, you just named cells. I wanna know that process.

[@alexandragomez2687]

@@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..

[@shahin2324]

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

[@shaheeralam4948]

That was a good summary...

[@user-lr2nl1hv3b]

[@thanveersuresh4620]

dats cool

[@isaacculents]

should've let a Clinical Laboratory Scientist / Medical Technologist give the lesson

[@hb6839]

Wow she didn't even explain hematopoeisis properly

[@Lenajos]

Funny "....in science we never use plain and ordinary names..."

[@nickkiernanwalker]

Is this on the Khan Academy website? Can't seem to find it

[@user-jh5go3uk8c]

It wasn't detailed enough..just basics wouldn't help

[@saqlainmushtaq2253]

I want hemopoiesis process

[@digen4656]

What colour would you choose for the bacterium?

[@Stilllife1999]

'In science we never use the plain and ordinary name.' 🤔

[@gaylegaming1063]

mam.. where are u from...? but I like u in the way of approach the topics and clarify easily.. ❤❤❤ tq mam

[@prestonkoehn2323]

The RBCs look more like cough drops than dumbells

[@silentrefusal9911]

No detail of haematopoisis from embryonic till adulthood. And no mention of sites of haematopoeisis. Neither the main progenitors.??

[@mofizulrahaman9252]

💖💖

[@courtneyglamour3469]

You didn't mention NK Cells :(

[@MasudRana-po3ii]

Leukocytes?

[@dr_gill8886]

😘

[@gilbertgrejp]

NK cells?

[@mouadmaskini7702]

aren't monocytes lymphoid cells and not myeloid

[@sunnykem646]

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.

[@vidya.v]

sunny kem pluripotent hematopoietic stem cell or haemocytoblast

[@Dratifkhattak]

Why the centre of red blood cell is so thin

[@shirleylindo7203]

Good question

[@marymessam2435]

Good lecture but kinda lacks details!

[@theart4022]

you did not talk about the basic process

[@alessandrogagliardi7470]

some problems with the spell

[@alext8828]

Question: Eosinophils are red because the dye used to identify them (eosin) is brick red??? Am I wrong here?

[@arnisbirze1724]

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.

[@tanimrahman2051]

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!

[@slampest]

This has nothing to do with hematologic system diseases though

[@me1yz]

did she actually told scary Greek word hematopoiesis lol

[@AN-pu9zj]

10 minutes of nothing...

[@occupytosavetheworld]

what is this female voice.. what happened to khan I'm pissed

[@rollandjonathan8085]

You haven't detail the process of haemopoiesis! You are talking too much and and can't understand your lecture.

[@TheHeatherchristyn]

please stop saying the words you're writing over and over as you write them "myeloid, mmyyyeellooiiddd group, myeloid" its incredibly annoying...

[@sjas8128]

So so disappointing...
