Answer:

The true statement is option B.

Explanation:

The systemic circuit is the component of the circulatory system, which carries the blood from the heart, and supply it to the majority of the organs and tissues, and returns it back to the heart. The oxygenated blood from the lungs goes into the left atrium and is mediated towards the left ventricle in order to supply the blood to the organs of the body.  

The systemic circuit is different from the pulmonary circuit that only mediates blood between the heart and lungs.
