What describes systemic circulation?

  1. Flow of blood from the heart to the lungs

  2. Flow of blood from body tissues to the heart

  3. Flow of blood from the heart to the body tissues and back

  4. Flow of oxygenated blood to the brain

The correct answer is: Flow of blood from the heart to the body tissues and back

Systemic circulation refers to the pathway in which oxygen-rich blood is pumped from the heart to the rest of the body to supply organs and tissues with the oxygen and nutrients they need. After delivering these essential components, the blood returns to the heart, now deoxygenated, to be sent back to the lungs for re-oxygenation. This comprehensive circuit allows for the distribution of blood throughout the body and is essential for maintaining overall physiological function. The correct answer highlights both the outward flow of oxygenated blood to body tissues and the return of deoxygenated blood back to the heart, encapsulating the entire systemic circulation process. Other options focus on more specific pathways or subsets of circulation, such as the pulmonary circuit (which pertains to the flow of blood to and from the lungs) or the flow of blood returning specifically from tissues, but do not encompass the full systemic circulation cycle.
