Time takes a toll on the organs and systems in the body. People are likely to notice a number of changes as they get older.

How and when these changes occur is unique to each person. A healthy aging feature on MayoClinic.com outlines the typical changes individuals can expect as they age. Here are a few changes highlighted in the feature:

Cardiovascular system

As people age, the heart muscle becomes a less efficient pump, working harder to pump the same amount of blood through the body. Also, blood vessels become less elastic.

Bones, muscles and joints

Bones reach their maximum mass between ages 25 and 35. As people age, their bones’ size and density shrink. Some people might become shorter. Gradual loss of density weakens bones and makes people more susceptible to fracture.

Digestive system

Swallowing and the motions that automatically move digested food through the intestines slow down as people get older. The amount of surface area within the intestines diminishes slightly.

Weight

As men and women age, maintaining a healthy weight may be more difficult. Metabolism generally slows, meaning that the body burns fewer calories.
