Final answer:
The network that transports blood in the circulatory system is made up of the heart, veins, and capillaries. Arteries also play a vital role, carrying oxygen-rich blood away from the heart to the body.
Step-by-step explanation:
The parts of the circulatory system that make up the network responsible for transporting blood throughout the body include the heart, the veins, and the capillaries. The arteries are also a crucial part of this network, carrying oxygenated blood away from the heart.
Together, these components facilitate the continuous flow of blood to supply the body's tissues with necessary nutrients and oxygen, and to remove waste materials. The heart acts as the pump in this system, propelling the blood into the arteries which then branch into smaller arterioles and lead into the vast network of capillaries. It is within the capillaries where the exchange of gases, nutrients, and wastes occurs. The blood then gathers into venules, which coalesce into veins to return the deoxygenated blood back to the heart.
