b)     Coronary arteries

c)      Superior vena cava

d)     Inferior vena cava

e)      Pulmonary veins

f)       Pulmonary arteries

g)      Pulmonary trunk

h)     Brachiocephalic trunk

2.      The valve located between the left atrium and left ventricle is the

a)      Ileocecal valve

b)     Mitral valve

c)      Tricuspid valve

d)     Aortic valve

e)      Pulmonary valve

3.      Given these valves:

Arrange them in the order in which an erythrocyte would pass through them after returning to the heart from the left arm.

a)   A   à  M à  P à  T

b)   M  à  A  à  P à  T

c)    T  à   P  à  M à  A

d)   A  à   P  à  M à  T

e)    T  à   P  à  T  à   P

4.      After systole the blood leaves the left ventricle through the

a)      Aorta

b)     Pulmonary trunk

c)      Coronary sinuses

d)     Inferior vena cava

5.      In healthy people the blood circulating in the pulmonary trunk is

a)      Very rich in oxygen

b)     Poor in oxygen

6.      In healthy people the blood that passes through the mitral valve is

a)      Oxygenated

b)     Deoxygenated

7.      In healthy people there is a normal communication between the right and left ventricles

a)      True

b)     False
