Kardiovaskulaarsüsteemi

Kardiovaskulaa refers to the body's circulatory system, primarily consisting of the heart, blood vessels, and blood. This intricate network is responsible for transporting oxygen, nutrients, hormones, and other essential substances throughout the body. It also plays a crucial role in removing waste products such as carbon dioxide. The heart, a muscular organ, acts as the central pump, continuously circulating blood through a vast network of arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart, while veins return deoxygenated blood to the heart. Capillaries are tiny blood vessels where the exchange of oxygen, nutrients, and waste products occurs between the blood and the body's tissues.

A healthy cardiovascular system is vital for overall well-being. Conditions affecting this system, collectively known as cardiovascular diseases, are a leading cause of mortality worldwide. These diseases can include issues like atherosclerosis (hardening of the arteries), hypertension (high blood pressure), heart failure, and stroke. Lifestyle factors such as diet, exercise, smoking, and stress significantly influence cardiovascular health. Maintaining a balanced diet, engaging in regular physical activity, avoiding tobacco, and managing stress are key strategies for promoting a healthy kardiovaskulaa system and reducing the risk of cardiovascular problems. Medical professionals monitor and assess kardiovaskulaa function through various diagnostic tools and treatments.
