What is the vascular system called that carries blood through the body delivering oxygen and nutrients and removing waste?

• A. The Vascular System
• B. Circulatory System
• C. Lymphatic System
• D. Immune System

Answer: (A)

The main idea here is the body’s transport system that moves blood to every tissue, delivering oxygen and nutrients and removing wastes. This is the circulatory system. It includes the heart, which acts as a pump, and the network of blood vessels—arteries, veins, and capillaries—that carry blood throughout the body. Through the vessels, oxygen-rich blood is sent to cells, nutrients travel with the blood, and waste products are carried away to be removed or processed. The term vascular system can refer to the blood vessels themselves, but the standard name for this whole transport system is the circulatory (cardiovascular) system. The lymphatic system and the immune system have important roles in fluid balance and defense, but they are not the primary systems responsible for delivering oxygen and nutrients to tissues and removing metabolic wastes from circulation.
