1
Q

functions of the cardiovascular system

A
  1. transport nutrients, gases, & waste products around the body
  2. Protect the body from infections and blood loss
  3. help the body MAINTAIN A CONSTANT BODY TEMPERATURE (heat from muscle contractions)
  4. helps MAINTAIN FLUID BALANCE within the body

Q

Define: Basophils

A

relates HEPARIN AND HISTAMINE
inhibits blood clotting
less than 1% of WBC

18
Q

plasma % and definiton

A

55%
non -cellular fluid portion of blood, H2O, nutrients, gases, hormones, waste

19
Q

RBC and hemoglobin

A

RBC transport hemoglobin and makes blood appear red the bound to OXYGEN IN ARTERIES

20
Q

BLOOD APPEARS WHAT IN VEINS

A

DEOXYGENATED

21
Q

PRODUCTION OF ERYTHROPOIESIS

A

occurs in the yolk sauce, liver and steel before birth
STIMULATED: DECREASE IN OCYGEN, BLOOD LOSS AND CHRONIC LUNG DISEASE
CARBON DIOXIDE INCREASES

22
Q

ERYTHROPOIESIS (PRODUCTION)

A

low blood oxygen(hypoxia)causes kidneys and liver to release ___ERYTHROPOIWTIN_____ (hormone) which stimulates RBC production

NEGATIVE-FEEDBACK

23
Q

DEFINE: BLOOD PLATELETS

A

cell fragments of megakaryocytes-

24
Q

DEFINE: PLASMA

A

liquid portion of blood
related to blood pressure
97% water

25
Q

function of plasma

A

transport nutrients and gases, regulate fluid and electrolyte balance, and maintain a favorable pH.

26
Q

what is hemostasis

A

STOPPPAGE OD BLEEDING, EFFECTIVE WHEN SMALL BLOOD VESSELS ARE DAMAGED.

27
Q

3 steps of hemostasis

A

vascular spasm
platelet plug formation
formation of clot

28
Q

what is coagulation

A

formation of clot

29
Q

what is proteins on the surface of RBCs , cell surface makers

A

antigens

30
Q

what is

A

proteins free floating in plasma that bind to like antigens; are against the antigens

31
Q

what is agglutination

A

clumping of red blood cells in response to a reaction between an antibody and an antigen

32
Q

what is RH positive and Rh negative

A

presence of Rh antigens on the red blood cell membranes,

negative ; lack of antigens

33
Q

what is Disorder in newborn infants resulting from destruction of fetal RBCs by maternal antibodies

A

Erythroblastosis Fetalis

34
Q

Erythroblastosis Fetalis

A

Rh - women gives birth to a RH + baby
baby’s RBC enter the mothers blood stream
mother beings to BUILD ANTI- RH ANTIBODIES

MOTHER HAS 2ND RH + BABY

Mother’s anti-Rh antibodies pass into the fetus’ blood stream
RESULTING IN AGGLUTINATION OF BABY’S RBC ( BLOOD CLOTTING)

35
Q

BLOOD TYPE: AB IS UNIVERSAL RECIPETIN OR DONOR

A

RECIPIENT

36
Q

BLOOD TYPE: TYPE O IS UNIVERSL DONOR OR RECIPIEITN

A

DONOR

37
Q

BLOOD TYPE A

A

A antigens, B anti bodies

38
Q

blood type B

A

b antigens , a uni-bodies

39
Q

blood type ab

A
