Physiology of Aging

The physiology of aging refers to the natural changes in the body's structure and function over time. As we age, organs become less efficient, muscle mass decreases, bone density may weaken, and skin loses elasticity. Cell repair and renewal slow down, affecting energy levels and immune response. Blood vessels may stiffen, raising blood pressure, and senses like hearing and sight can decline. These gradual changes are normal and vary between individuals. Overall, aging involves complex processes that influence physical health, highlighting the importance of healthy habits to support well-being throughout life.
