Explanation:

Aging is understood to mean the physiological changes that occur over time in multicellular organisms. To further detail, such changes occur in molecules and cells that ultimately impair the functioning of organs and the body in general. The causes of such a period can be divided by considering the genetics, lifestyle and environment in which a person lives. Aging physiologically affects all cells and all systems in the body. As cells get older, membrane cells change, so body tissues have more trouble getting oxygen and nutrients and removing carbon dioxide and waste.
