What are the two divisions of the circulatory system?

  1. Cardiac and systemic

  2. Systemic and pulmonary

  3. Venous and arterial

  4. Coronary and pulmonary

The correct answer is: Systemic and pulmonary

The two divisions of the circulatory system are systemic and pulmonary. The systemic circulation is responsible for delivering oxygenated blood from the heart to the tissues of the body and returning deoxygenated blood back to the heart. This ensures that all body cells receive the oxygen and nutrients they need to function properly. In contrast, pulmonary circulation involves the movement of blood between the heart and the lungs. The heart pumps deoxygenated blood to the lungs, where it is oxygenated and then returned to the heart to be pumped through the systemic circulation. Understanding these two divisions is essential for recognizing how blood flow supports metabolic processes and overall homeostasis within the body. Each division plays a crucial role in maintaining the body's oxygen levels and removing carbon dioxide and other waste products.
