1

What are the components of blood?

55% Plasma
45% Enterocytes

2

What are neutrophils?

white blood cells

3

what are leukocytes?

white blood cells

4

What are erythrocytes?

red blood cells

5

What is the main component of plasma?

Water (90%)

6

What is the benefit of plasma being mainly water?

Can dissolve things into it for transportation; Na, K, Cl, Ca, Bicarbonate, O2, CO2,

7

What are the proteins in the plasma?

albumins, globulins/immunoglobulins, fibrinogens

8

What is the role of albumins?

regulate water concentration

9

What is the role of immunoglobulins?

defend against bacterial cells / antigens

10

What is the role of fibrinogen?

clotting protein

11

What is an antigen?

foreign protein in the blood

12

Where do red blood cells get their energy from?

glycolysis because there is no mitochondria

13

What is the size of a red blood cell?

12um

14

What is the main component of red blood cells?

haemoglobin - 250 million molecules each cam carru 4 molecules of oxygen

15

Where are red blood cells made?

bone marrow

16

How does the body regulated dead red blood cells?

broken down in spleen

17

Where are red blood cells?

only in blood vessels and the heart

18

What is the lifespan of a red blood cell?

120 days max

19

What are the two main categories of white blood cells?

Granular and Agranular

20

What does granular/agranular mean?

Show spots with stain, agranular doesn't

21

What are the two kinds of agranular white blood cells?

Monocytes and Lymphocytes

22

What are the two kinds of lymphocytes?

T Cells and B Cells

23

What disease is often correlated to T Cells?

HIV, becomes AIDS when the concentration of T Cells reaches a certain level

24

What are the three kinds of granular

Eosinophils, basophils, neutrophils,

25

What are eosinophils?

immune cell causing inflamation

26

What are basophils?

white blood cell that helps coagulate blood, has histamine to promote blood flow to tissues

27

What are neutrophils?

Pac Man

28

What happens to white blood cells?

become puss

29

Where are white blood cells made?

Bone marrow and spleen, mature in thymus

30

Where are white blood cells found?

Vessels, heart and interstitial fluid
