What characterizes systemic circulation?

Systemic circulation is characterized by the process in which oxygen-rich blood is pumped from the heart through the aorta to nourish and supply oxygen to all body tissues, before returning deoxygenated blood back to the heart through the venous system. This pathway is crucial for delivering essential nutrients and oxygen to various organs and systems throughout the body, facilitating metabolic processes, and removing waste products.

The systemic circulation is distinct from pulmonary circulation, which is specifically concerned with blood flow to and from the lungs for oxygenation. It also does not focus exclusively on the heart itself or isolate blood flow to a single area, such as the brain. Instead, it encompasses the entire body, highlighting the importance of this circulation in maintaining overall physiological function and homeostasis.
