20
Q

Body doesn’t make enough blood cells due to lack of B12

A

pernicious anemia

21
Q

RBC’s are destroyed faster than the bone marrow can produce them

A

hemolytic anemia

22
Q

Increased number of RBC’s

A

Polycythemia

23
Q

A hereditary disease which causes abnormally shaped RBC’s which rupture easily

A

Sickle cell disease

24
Q

Larger than RBC’s and have a nucleus

A

Leukocytes (WBCs)

25
Q

Found in blood vessels, lymph and tissue fluid

A

WBC’s

26
Q

5,000-11,000/mm3 of blood

A

WBC’s

27
Q

WBC’s that have granules in the cytoplasm

A

Granulocytes

28
Q

WBC’s that have no granules in cytoplasm

A

Agranulocytes

29
Q

What are the 3 types of granulocytes

A

Neutrophils
Eosinophils
Basophils

30
Q

Granules are small and numerated and give cytoplasm a coarse look

A

Neutrophils

31
Q

First granulocytes to appear at an infection and phagocytize bacteria (65% of WBCs)

A

Neutrophils

32
Q

Protect against infections by parasitic worms and increases in number during allergic reaction (2-5% of WBCs)

A

Eosinophils

33
Q

Granules are large and sparse and release histamines in damaged tissue, causing vascular dilation and smooth muscle contraction in the walls of air passages

A

Basophils (.5-1%)

34
Q

What are the two types of agranulocytes

A

Lymphocytes 25%

Monocytes 3-8%

35
Q

What are 2 types of lymphocytes

A

T lymphocytes

B lymphocytes

36
Q

Directly kill infected cells or cancer cells

A

T lymphocytes

37
Q

Produce antibodies against specific antigens and deactify toxins

A

B lymphocytes

38
Q

Very mobile and very phagocytotic

A

Monocytes

39
Q

Cancers that causes overproduction of abnormal WBC’s

A

leukemia

40
Q

Prevents leukemic cells from moving into the CNS

A

craniospinal irradition

41
Q

Cells involved in clot formation

A

platelets

42
Q

Occurs in individuals that lack clotting ability

A

hemophilia

43
Q

Functions of blood

A
  • maintain homeostasis
  • regulate temp
  • buffers to maintain pH
  • transports
  • Fights infection
44
Q

Prevents blood loss from a broken blood vessel

A

hemostasis

45
Q

What are the 3 major steps in hemostasis

A
  1. Vascular spasm
  2. Formation of platelet plug
  3. Blood coagulation
46
Q

Mother’s immune system may attack infant’s RBC’s (erythroblastosis fetalis)

A

Rh factor

47
Q

What is the treatment for Rh factor?

A

RhoGAM is given to mother to prevent her immune system from producing Rh antibodies
