What are the components of the transport system in human beings? What are the functions of these components?
The main components of the transport system in human beings are the heart, blood, and blood vessels.
- The heart pumps oxygenated blood throughout the body. It receives deoxygenated blood from the various body parts and sends this impure blood to the lungs for oxygenation.
- Blood helps in the transport of oxygen, nutrients, CO2, and nitrogenous wastes.
- The blood vessels (arteries, veins, and capillaries) carry blood either away from the heart to various organs or from various organs back to the heart.
