The Cost of an Aging Population
We are all getting older and like an old car our parts start to wear out. That will not change but we as individuals can delay the effect of aging with physical and mental exercise. Our organs lose some of their function at a set rate each year. For example, bone mineral density goes down about 1 percent per year beginning about 30, and so does lung function, heart function, muscle mass, etc. Good data shows that exercise slows the rate of loss of bone mineral density, heart function, lung function, muscle tone, and improves mobility, strength and a sense of well-being. Similarly, there is suggestive evidence that exercising the brain slows down memory loss and may delay the
Breathing is a vital function of life. Your lungs allow your body to take in oxygen from the air and get rid of carbon dioxide, a waste gas that can be toxic.
The intake of oxygen and removal of carbon dioxide in the lung is called gas exchange. When you breathe in, air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air enters the alveoli (air sacs). Oxygen from the air passes through the very thin walls of the alveoli to the surrounding blood vessels. At the same time, carbon dioxide moves from the blood vessels into the air sacs to be exhaled.
