The correct answer is B. Systemic circulation refers to the path of blood as it moves from the heart throughout the body and back to the heart. To understand this concept, it's important to understand the circulatory system.
The circulatory system consists of the heart, blood vessels, and blood. The heart is responsible for pumping oxygenated blood to the rest of the body and receiving deoxygenated blood from the body. This movement of blood is known as circulation.
Systemic circulation specifically refers to the path that oxygenated blood takes as it exits the left side of the heart and is pumped out to the body tissues through the arteries. The oxygen and nutrients in the blood are then delivered to the body's cells, and waste products like carbon dioxide are removed. After passing through the body's capillaries, the blood then returns to the right side of the heart through the veins, completing the systemic circulation.
To remember this concept, you can think of the term "systemic" as relating to the whole body.
