Question 43
F

A baby is born with a small hole in the septum between the two ventricles. Which statement explains why the baby becomes tired very easily?

[1]
A

Deoxygenated blood mixes with oxygenated blood, so the cells receive less oxygen

B

The valves between the atria and ventricles leak, so blood flows back into the atria

C

Blood is pumped to the lungs twice, so the pressure in the lung capillaries is high

D

The wall of the left ventricle becomes thinner, so the heart beats more slowly
