Q

How do measurements of fasting plasma glucose relate to health?

A

Diabetes!
When the body doesn’t make enugh insulin- cells can’t use glucose to meet energy needs (FBG > 125)

17
Q

Granulocytes

A

Neutrophil, Eosinophil, Basophil

18
Q

Agranulocytes

A

Lymphocytes, Monocytes

19
Q

The most abundent plasma protein is

A

albumin

20
Q

Two major roles of albumin (plasma protein)

A

transporting substances, preventing fluid leakages

21
Q

important plasma protein involed in blood clotting

A

fibrinogen

22
Q

fluid component of the blood, minus the formed element

A

plasma

coagulants: Finrinogen
proteins: albumin, globulin

23
Q

oxygen-binding protein in RBCs

A

hemoglobin

24
Q

RBC characteristics

erythrocytes

A

No nucleus, motochondria, or other organelles

-most numerous of formed elements

25
Q

how does polycythermia affect blood flow (increased in RBC numbers)

A

makes blood thicker- slower flow

26
Q

what is anemia? common causes?

A

Not enough healthy RBCs

iron deficiency+ blood loss

27
Q

What are WBCs (leukocytes) for

A

function in body’s defense systems by mounting inflammatory or immune responses

-granulocytes or agranulocytes depending on weather or not they contain membrane bound granules in their cytoplasm

28
Q

Neutrophils

A

-most numerous WBCs- 50-70% of total WBC population

-phagotyse and destory bacteria and other pathogens

29
Q

Eosinophils

A

-combat parasitic infections
-modulate allergic/ inflammatory repsonses
-phagocytize antigen-antibody complexes

30
Q

basophills

A

release histamine and heprin for inflammaftion repsonses

31
Q

lymphocytes

A

B cells: produce antibodies to attack bacteria, virus, and toxins
T cells: plays a roll in cell-medicated immunity- coordinates immunity response

32
Q

monocytes

A

turn into macrophages

-important in chronic infections

33
Q

chronic vs acute leukemia

A

chronic: slower-progressing accumulation of more mature, but abnormal WBCS

Acute: rapidly progressing- proliferation of immature blood cells

34
Q

platelets

A

are smaller, no nucleus, role in blood clotting

-originates from bone marrow cell called a megakarocyte

-participate in homeostatis by stopping bleeds

35
Q

rarest blood type

A

AB-

36
Q

universal donor

A

O-

37
Q

universal recipient

A

AB+

38
Q

what blood sample did not aggluinate with any antibodies tested

A

o- because agglunation occurs when A,B, or RH antigens are present

o- dont have any
