When the ventricles contract, blood is pumped
A
out of the heart
B
in the heart
C
in veins
D
in the septum
Explanation: 

Detailed explanation-1: -When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body’s tissues.

Detailed explanation-2: -After the ventricle fills and transitions to contracting, the pressure eventually exceeds that of the blood vessels. This gradient closes the mitral valve, which marks the beginning of systole and causes the first heart sound (in concert with the tricuspid valve), denoted as S1.

Detailed explanation-3: -The heart is divided into a right and left side, separated by a septum. Each side has an atrium (which receives blood as it enters) and a ventricle (from which blood is pumped out).
