Answer 2

The human body is made up of trillions of cells closley packed together. Each cell generates wastes that must be regularly removed, and each cell requires a constant supply of water and energy. An efficient network for transporting materials is required to keep cells functioning properly.

The human circulatory system performs four key functions:

• transports and delivers oxygen and nutrients (e.g., minerals, vitamins, and glucose) to the body's cells in exchange for carbon dioxide and wastes

• transports and delivers chemical messengers - such as hormones - throughout the body

• distributes body heat

• defends againgst disease
