O.k. So on this video we're going to be talking about the changes in the body and the importance of exercise. Exercise can be put into two categories; preventative and protective affects. So let's first look at the body and the changes that occur in the body to better understand these preventative and protective affects. So, first off, your body can be broken down into different types of tissues. For instance, you have muscle tissue and bone tissue, and the function of those tissues is based on the cell's function within that tissue. So the muscle tissue has specific functions related to muscles and contraction, and the bone tissue has specific functions to bones and production of calcium and things like that for structure. And as we age, all of these tissues in our body are replaced and regenerated at different stages in our life. Sometimes this happens on a weekly process. For some other tissues, it happens over years and years. And almost all the cells in your body are replaced at some point in your life. And so, for instance, with exercise, your tissues are torn every time you exercise. There are micro tears that occur within that tissue, and as a normal process after your exercise, those tissues are repaired. And how that relates to exercise and the aging process is going to be the next part of this video series.
