As we age, our bodies undergo a complex series of biological changes, many of which contribute to the gradual decline in cellular function. These changes include a decrease in the body's ability to ...

The circulatory system transports substances between the exchange surface and cells. It delivers oxygen and glucose to the tissues for respiration, which is the release of energy to cells.
