In the systemic system, blood is circulated to which part of the body?

The systemic system refers to the part of the circulatory system responsible for delivering oxygenated blood from the heart to the various tissues throughout the body and then returning deoxygenated blood back to the heart. This encompasses all the organs and tissues, ensuring they receive the necessary nutrients and oxygen to function properly.

In contrast, the heart and lungs participate in different pathways; the heart pumps blood, while the lungs are involved primarily in the exchange of oxygen and carbon dioxide, which is part of the pulmonary circulation. The liver, though vital for processing blood and nutrients, is also included within systemic circulation as it receives blood, but it is just one of the numerous organs served by the systemic system. Therefore, when considering the question about blood circulation in the systemic system, the correct focus is on the entire body, as it signifies the scope of systemic circulation.
