Circulatory System

The circulatory system, also known as the cardiovascular system, is a complex network that functions to deliver oxygen, nutrients, and hormones to cells throughout the body while removing carbon dioxide and metabolic wastes. It consists of the heart, a muscular pump, and a system of vessels, including arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to tissues, while veins return oxygen-poor blood back to the heart. Capillaries, the smallest vessels, facilitate the exchange of substances between the blood and body tissues.

From a medical perspective, the circulatory system is crucial in maintaining homeostasis and enabling efficient cellular function. The heart's rhythmic contractions maintain blood flow, regulated by electrical impulses and influenced by various physiological factors. Disorders of the circulatory system, such as atherosclerosis, hypertension, myocardial infarction, and stroke, can have significant health impacts. Treatment and management of circulatory issues depend on accurate diagnosis through clinical evaluation and diagnostic tests such as ECG, stress tests, angiography, and blood analyses. Maintaining a healthy circulatory system is often advised through lifestyle choices, including a balanced diet, regular exercise, and avoidance of smoking and excessive alcohol consumption.
