To make it foldable and increase the surface area of the cell

10
Q

What does hemoglobin require?

A

Iron

11
Q

What does iron do in hemoglobin?

A

When hemoglobin is exposed to oxygen, oxygen binds to the iron and created oxyhemoglobin

12
Q

What are erythrocytes?

A

Red blood cells

13
Q

What are red blood cells?

A

Erythrocytes

14
Q

What do erythrocytes do?

A

They transport oxygen from lungs to tissues, and carbon dioxide from tissues to lungs

15
Q

What is unique about erythrocytes?

A

They have almost no organelles and they have no nucleus. Also, they can’t divide

16
Q

What shape are erythrocytes?

A

They’re donut shaped

17
Q

How many red blood cells are there in the body?

A

20-30 trillion red blood cells

18
Q

What does erythropoietin do?

A

It decreases the number of red blood cells

19
Q

What does hematapoesis do?

A

It forms blood cells in the red bone marrow

20
Q

How and where are blood cells formed?

A

They’re formed via hematapoesis in the red bone marrow

21
Q

What are the proteins in plasma?

A

Albumin, globulin, and fibrinogen

22
Q

What does albumin do?

A

It helps maintain water balance

23
Q

What does globulin do?

A

It helps transport and the immune system

24
Q

What does fibrinogen do?

A

Helps blood clots form

25
Q

What is erythropoesis?

A

The process that balances the production and destruction of red blood cells

26
Q

What do stem cells do?

A

They can turn into almost any kind of blood cell

27
Q

What happens do destroyed ethyrocytes?

A

The iron is salvaged and stored and the heme is degraded into bilirubin

28
Q

Where does bilirubin come from and go?

A

It comes from the heme and is moved to the liver, where it’s secreted into the bile and feces

29
Q

What does heme turn into and come from?

A

It comes from erythrocytes and is degraded into bilirubin

30
Q

What causes anemia?

A

It’s an insufficient number of red blood cells and iron

31
Q

What is a transfusion reaction?

A

It’s when the antibodies attack the antigen and cause agglutination

32
Q

What are the different blood types?

A

A, B, AB, and O

33
Q

What antigens and antibodies does blood type A have?

A

It has A antigens and B antibodies

34
Q

What’s an antigen?

A

The protein

35
Q

What’s an antibody?

A

The fighty thing

36
Q

White blood cells

37
Q

A

Less than 1%

38
Q

What is a white blood cell called?

A

A leukeocyte

Q

What is diapedesis?

A

When leukocytes move out of the capillaries
