What is systemic circulation?

Answer 1

Systemic circulation refers to the part of the circulatory system that carries oxygenated blood from the heart to the body's tissues and returns deoxygenated blood back to the heart. It involves the flow of blood through the arteries, capillaries, and veins throughout the body, excluding the lungs. In systemic circulation, oxygen and nutrients are delivered to the organs and tissues, while waste products such as carbon dioxide are removed. This process ensures that the body's cells receive the necessary oxygen and nutrients for their proper functioning.
