Q

erythroblastosis fetalis

A

AKA hemolytic disease of the newborn

caused when an RH- mother has a second RH+ child. newborn will have a deficiency of RBCs due to mothers antibodies entering the fetal bloodstream

look for RBCs with nucleus

21
Q

hematocrit

A

measure of the percent of RBCs in a sample

22
Q

two conditions that can result in an increased hematocrit

A

dehydration
lung or heart disease

23
Q

two conditions that can result in a decreased hematocrit

A

hemolysis
vitamin/mineral deficiency

24
Q

source of antibodies in the antibody-mediated immune response

A

B cells

25
Q

antigen

A

are on the surface of erythrocytes

26
Q

antibodies

A

react to specific foreign antigens, destroy them

27
Q

autoimmune diseases

A

when your body produces antibodies for its own antigens

28
Q

agglutination

A

clumping of RBCs due to antigen antibody reaction

29
Q

clotting/coagulation

A

converting blood into a semisolid jelly substance

30
Q

rules of the blood typing test thing

A

clumps = antigen is present

thats it

31
Q

hypoxia

A

low O2 levels in tissues

32
Q

hypoxemia

A

low O2 levels in blood

33
Q

anterior interventricular sulcus

A

shallow groove on anterior surface of heart that marks teh boundary between right and left ventricles

34
Q

coronary sinus

A

large sinus under right atrium (back side) that receives blood from the myocardium, empties into right atrium

35
Q

ligamentum arteriorsum

A

ligament that attaches the pulmonary trunk with the aorta

36
Q

pulmonary semilunar valve

A

prevents backflow of blood from pulmonary trunk to right ventricle

37
Q

aortic semilunar valve

A

prevents backflow of blood fro aorta to left ventricle

38
Q

AV valves

A

atrioventricular valves

one is each bridge between atria and ventricles, tri on right, bi of left

39
Q

chordae tendineae

A

connects tricuspid and bicuspid valves to papillary muscles to prevent cusps from swinging backward during systole

40
Q

papillary muscles

A

cone shaped trabeculae that attach to cordae tendineae that contract to prevent inversion

41
Q

fossa ovalis

A

remnant of foramen ovale, opening that allowed passage between left and right atria in the fetus

42
Q

interatrial septum

A

wall between atria

43
Q

opening of the coronary sinus

A

located in right atrium

44
Q

trabeculae carnae

A

raised bundles of muscle that lines ventricle walls

45
Q

source of serous fluid in the heart

A

parietal pericardium

46
Q

layers of pericardium and what is between

A

parietal pericardium (outer)
visceral pericardium (inner)

between them is the pericardial cavity

47
Q

fibrous layer of pericardium

A

superficial to the parietal pericardium`

48
Q

function of intercalated discs

A

connect cardiac muscle cells, coordinate contraction
