Cardiovascular

The cardiovascular system is a complex network of organs, including the heart and blood vessels, that work together to ensure proper blood flow throughout the body. Its primary components are the heart, blood vessels, and blood. The heart functions as a pump, circulating oxygen-rich blood throughout the body and receiving oxygen-depleted blood in return. The blood vessels, consisting of arteries, veins, and capillaries, form an extensive network that carries the blood. Blood itself is made up of three key components: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes), which transport oxygen, nutrients, and waste products.

Common cardiovascular diseases include stroke, pericarditis, hypertension, angina, and arrhythmia. To maintain a healthy cardiovascular system, it’s important to exercise regularly, avoid smoking and alcohol, and eat a balanced diet.
