29
What is part of the blood flow through the heart
left atrium
30
Blood type called the universal recipient
type ab
31
event that causes the pulmonic valve to open
an increase in the pressure within the right ventricle
32
Name of valve that prevents backflow of blood into the right atrium when right ventricle contracts

36
red and white blood cells are
produced in the bone marrow
37
Which of the following is responsible for the opening and closing of the heart valves?
Pressure exerted on the valves as the heart contracts and relaxes
38
what is located between the visceral and parietal pericardium
a space that contains serous fluid
39
Why may a person who has had a gastrectomy (removal of the stomach) develop pernicious anemia?

red blood cells
48
most related to biconcave disc, hemoglobin, and erythropoietin
red blood cell
49

phagocytic.
50
not true of the heart
the pericardium is composed of actin and myosin
51
when is coronary blood flow greatest
during myocardial relaxation
