THE HEART AND THE CARDIOVASCULAR SYSTEM

Аннотация

The cardiovascular system, also known as the circulatory system, is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body. It comprises the heart, blood vessels, and blood, playing a crucial role in maintaining homeostasis and regulating body functions. The heart, a muscular organ with four chambers and valves, ensures continuous blood circulation through the pulmonary and systemic circuits. Blood vessels, including arteries, capillaries, and veins, facilitate nutrient and gas exchange. The regulation of blood pressure and heart rate is influenced by baroreceptors, hormones, and the autonomic nervous system. Cardiovascular diseases, such as hypertension, coronary artery disease, and stroke, remain major health concerns. Preventive measures, including a healthy diet, regular exercise, stress management, and medical check-ups, contribute to maintaining cardiovascular health. Understanding the structure, function, and common diseases of the cardiovascular system isessential forpromoting heart health and preventing complications.
