The heart is a vital organ that ensures blood circulation and supplies tissues with oxygen and nutrients. Its anatomical structure consists of four chambers, valves, and a complex vascular network. With aging, various structural and functional changes occur in the heart, affecting the health of the cardiovascular system. This article analyzes the heart's anatomy, its structural components, their physiological functions, and age-related changes. Understanding these transformations is crucial for identifying and preventing age-associated cardiovascular diseases.
