The question asks from which chamber of the heart does oxygenated blood make its way to the rest of the body via the Systemic Circuit?
The answer is C - the left ventricle.
As for the descriptions you asked for, a simple description of the circulatory system is that it's split into 2 parts - the Systemic Circuit and the Pulmonary Circuit.
- The Systemic Circuit delivers oxygenated blood from the heart to the rest of the body. It travels from the left ventricle (the answer to your question) into the rest of the body through the aorta, which splits up into smaller arteries that shuttles blood to the tissues.
- The Pulmonary Circuit delivers deoxygenated blood from the heart to the lungs in order to allow the blood to exchange the CO2 it is carrying for Oxygen. The pathway starts when the blood exits the right ventricle into the pulmonary artery and travels to the lungs, where it exchanges gases, then travels back to the heart via the pulmonary vein. The oxygenated blood then feeds into the systemic circuit.
