What are white blood cells

A

Involved in immune system, warriors, attack bacteria u

2
Q

What are platelets

A

Involved in blood clotting, stop bleeding

3
Q

What are red blood cells

A

Carry oxygen

4
Q

What 3 types of suspended cells are contained in plasma

A

Red blood cells (erythrocytes)
White blood cells (leukocytes)
Platelets

5
Q

What percentage of water does plasma contain and what are the other bits

A

90% dissolved substances, mostly protein

6
Q

What is the percentage is plasma of total blood volume

A

55%

7

How much are red blood cells of total blood volume? What is the percentage of cells in blood

A

45% and 99%

8
Q

What is hemoglobin ( carried by red blood cells)

A

An iron containing proteins that binds about 97% of all oxygen in body

9
Q

Is oxygen soluble in water

A

Not very - it needs a carrier like hemoglobin to travel around the bloodstream

10
Q

How does the shape - name it - affect oxygen exchange

A

Discotic - doughnut with no hole - increases surface area

11
Q

Type A

A

Protein A and antibodies to protein B receive A, AB, d

12
Q

Type B

A

Protein B and antibodies to protein B receive B, AB,D

13
Q

Type AB

A

Both proteins so a universal receptor because of its lack of antibodies will not attack - A, B, AB, O

14
Q

Type O

A

No proteins and both antibodies - universal donor - because it’s lack of proteins will not be attacked

15
Q

What do white blood cells do

A

Defend against external organisms, clean up dead cells and tissue debris that could accumulate and lead to damage

16
Q

What do white blood cells have to do with infections

A

Infections stimulate the body to release a large number of protective leukocytes into the bloodstream

17
Q

What ispus

A

Dead white blood cells - accumulate

18
Q

What do platelets do

A

Do damage control by getting trapped at site and plugging leak

19
Q

What causes the clotting?

A

Protein in the plasma causes blood coagulation, like a tangled net of fibres that immobilize the fluid portion of blood
