Question

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

Answer 1

The transport system in humans consists of a pump called the heart, which propels the fluid called blood around a complex system of tubes called blood vessels. As it passes through these blood vessels, the blood picks up oxygen from the lungs and transports it to every cell in the body. Blood also picks up waste products such as carbon dioxide and many other substances like salts from the cells and eliminate them from the body.
