As you age, organs and tissues begin to lose some function. Changes occur in all of the body’s cells, tissues, and organs and these changes can?affect the functioning of?each??system.
Living tissue is made up of many types of cells. All have the same basic structure. Tissues are groups of cells that perform specific functions. Different kinds of tissues are grouped together? to form organs.
There are four basic types of tissue:
Connective tissue supports other tissues and binds them together. This includes bone, blood, and lymph tissues, as well as the tissues that give support and structure to the skin and internal organs.
Epithelial tissue provides a covering. Skin and the linings of such internal ?passages? such as the gastrointestinal system, are made of epithelial tissue.
Muscle tissue includes three types of tissue:
- Striated muscles, are those that that move the skeleton (also called ?voluntary muscle?)
- Smooth?muscles are ?the muscles contained in the stomach and other internal organs (known as ?involuntary muscles?)
- Cardiac muscle, makes up most of the heart wall (also an involuntary muscle)
Nerve tissues are nerve cells (neurons) used to carry messages to and from various parts of the body. The brain, spinal cord, and other nerves are made of nerve tissue.
Organs have a reserve ability which changes with aging. The biggest changes occur in the heart, lungs, and kidneys. These changes appear slowly over time and are essentially what aging is all about. Medical science has determined that the aging?process can be slowed by adopting a healthy lifestyle.? This lifestyle includes regular?exercise,?healthy eating habits and a positive mental outlook.? ?Home care nursing?professionals can?assist?seniors with living a healthier lifestyle and?dealing with the physical and mental?aspects of aging.
