CARDIO VASCULAR

The cardiovascular system consists of the heart, blood vessels, and blood. Its primary function is to transport nutrients and oxygen-rich blood to all parts of the body and to carry deoxygenated blood back to the lungs. Abnormalities or injuries to any or all parts of the cardiovascular system can result in serious health complications. Common conditions that can affect the cardiovascular system include coronary artery disease, heart attack, high blood pressure, and stroke. This article explores the cardiovascular system, including its components and their functions. We also outline some common cardiovascular system diseases and their associated treatments. Components of the cardiovascular system The cardiovascular systemTrusted Source is the system responsible for delivering blood to different parts of the body. It consists of the following organs and tissues: The heart: A muscular pump that forces blood around the body. A closed system of blood vessels: These vessels include: Arteries: Vessels that carry blood away from the heart. Veins: Vessels that bring blood back to the heart. Capillaries: Tiny vessels that branch off from arteries to deliver blood to all body tissuesTrusted Source. There are two blood circulatory systems in the body. The first is the systemic circulatory system. This is the main blood circulatory system that transports blood to the organs, tissues, and cells throughout the body. The second is the pulmonary circulatory system. This circulatory system moves blood between the heart and lungs. It is where oxygen enters the blood and carbon dioxide leaves the blood.
