Q

blood leaving the subclavian artery flows directly into the______before flowing into the arm as the brachial artery

A

axillary

30
Q

the brachial vein:

A

drains blood from the radial and ulnar veins, then empties that blood into the axillary vein

31
Q

in which one of the following blood vessels is blood pressure the highest?

A

arteries

32
Q

in a centrifuged blood sample, the buffy coat between the formed elements and the plasma contains:

A

33
Q

there are an average of _____ WBC’s per cubic millimeter of whole blood

A

4,000-11,000

34
Q

the hormone that regulates the rate of erythrocyte production is called:

A

erythropoietin

35
Q

in ABO blood typing, type B blood would:

A

clump with anti-A serum

36
Q

the aortic semilunar valve is composed of:

A

three cusps and opens when the left ventricle contracts

37
Q

which one of the following is true concerning the lub-dub sounds of the heart:

A

the first sound is longer and louder and is caused by closure of the AV valves; the second sound is shorter and sharper caused by closure of the semilunar valves

38
Q

the umbilical vein carries:

A

oxygen and nutrients from the placenta to the fetus

39
Q

A

true

40
Q

universal donors can receive blood groups A, B, AB, and O

A

false

41
Q

Rh- related problems occur in pregnant Rh- women carrying an Rh+ baby

A

true

42
Q

an increase in blood vessel diameter causes arterial blood pressure to decrease

A

true

43
Q

the coronary sinus on the backside of the heart drains deoxygenated blood from the wall of the heart into the left atrium

A

true

44
Q

the iron-containing protein found in RBC’s that transports the majority of oxygen carried in the blood , is_____

A

hemoglobin

45
Q

persons who can receive blood transfusions from blood groups A, B, AB, and O are called _____

A

AB+

46
Q

The volume of erythrocytes within a given volume of whole blood, expressed as a percentage, is __________.

A

hematocrit

47
Q

explain the antigen-antibody response as it related to blood groups.

A

The red cells of an individual contain antigens on their surfaces that correspond to their blood group and antibodies in the serum that identify and combine with the antigen sites on the surfaces of red cells of another type. The reaction between red cells and corresponding antibodies usually results in clumping—agglutination—of the red cells
