Question

What are the components of the transport system in human beings? What are the functions of these components?

Answer 1

The main components of the transport system in human beings are the heart, blood, and blood vessels.

• 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.

• Being a fluid connective tissue, 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.
