Question 1

Stroke volume is the amount of blood pumped out by each ventricle of the heart in one minute.

Accepted Answer

A) True 
 B)False  False

Question 2

Name two shunts that bypass the lungs in a fetus. Briefly explain the structures these shunts connect.

Accepted Answer

1. The foramen ovale is a flap-like opening between the right atrium and the left atrium of the fetal heart. Some of the blood entering the right atrium flows directly into the left atrium, bypassing pulmonary circulation.
2. The ductus arteriosus is a vessel connecting the pulmonary trunk and the aorta. Blood that happens to enter the right ventricle is pumped into the pulmonary trunk, supposedly on its way to the lungs. However, that blood is transported from the pulmonary trunk through ductus arteriosus into the aorta.

A) ventricular diastole
