Question

multiple cholce question
the wall of the left ventricle is thicker than the wall of the right ventricle, because _.
o the left ventricle has to pump blood into the lungs
the left ventricle has to pump blood into the low resistance systemic circuit
the left ventricle has to pump blood to all other parts of the body
the left ventricle has to pump blood into the low resistance coronary circuit

Explanation:

The left ventricle pumps oxygenated blood to the entire body (systemic circulation), which requires more force compared to the right ventricle that pumps blood to the lungs (pulmonary circulation). A thicker wall provides the necessary strength for this more demanding task. The systemic circuit has higher resistance than the pulmonary circuit. The left ventricle does not pump blood into the lungs (that's the right ventricle's job), the systemic circuit has higher not lower resistance, and the coronary circuit is a small part of the overall circulation not the main reason for the left ventricle's thick wall.

Answer:

the left ventricle has to pump blood to all other parts of the body
