Cardiovascular System
The cardiovascular system plays a vital role in circulating blood throughout the body to maintain human life. The system consists of a heart and blood vessels that help delivers blood containing oxygen and nutrients to the body organs and tissues for function. The heart is a muscular body organ located on the left side of a human chest. The heart has four chambers are known as the right atrium, right ventricle, left atrium and the left ventricle. Blood travels through the four chambers by the heart muscle contracting and relaxing pumping blood to the body and lungs. Blood vessels such as the arteries and veins are what transport the blood away from the heart and to the heart. The arteries transport blood away from the heart to the body organs,
while veins transport blood back to the heart. The pulmonary artery sends deoxygenated blood to the lungs for gas exchange. Once the gas exchange has occurred oxygenated blood is then returned to the heart from the pulmonary veins, and then sent to the body through the aorta. Cardiovascular diseases can have a major impact on the heart’s circulatory system. It is important to have adequate blood perfusion throughout the body because without it the organs can suffer damage and decrease function. Cardiovascular diseases such as Coronary Artery Disease, Valvular disease, and hypertension can impair blood flow to major body organs creating a life threatening situation. When working in the medical field as a nurse it is imperative to know signs and symptoms, diagnostic tests, and treatment options available for a patient suffering from a cardiac disorder to receive optimal care.
