Q

What happens during Vascular spasm?

A

The blood vessel constricts, making the diameter smaller and reducing the amount of blood lost

17
Q

What happens during Platelet Plug Formation?

A

Collagen fibers are exposed during the blood vessel tears

18
Q

Anemia is a blood disorder in which

A

Blood has low O2 carrying capacity

19
Q

Anemia can be due to

A
  • Lack of RBCs

- Insufficient RBCs that don’t work properly

20
Q

Sickle Cell Anemia is a blood disorder in which

A

RBCs change shape under low O2 conditions

21
Q

What is the antigen?

A

The marker on the surface of the blood cell that allows for identification

22
Q

What is the antibody?
