  • The Good: Artificial Heart/Heart Transplant
    The Good: Artificial Heart/ Heart Transplants A natural heart has two pumps, each has two chambers. The right atrium pumps oxygen-depleted blood from the body into the right ventricle. The right ventricle pumps blood to the lungs. The left atrium sends aerated blood from the lungs into the left ventricle, which pumps blood out of the body. With each heartbeat, the two atria contracts together, followed by the large ventricles. Congestive heart failure is when the heart fails to pump blood....

    The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases, it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps the pure blood to the...

  • Chronic Diseases: Heart Disease
    Chronic Diseases: Heart Disease Heart disease is the most frequent condition affecting the heart, known as coronary artery disease. Over time, a buildup of cholesterol creates a substance of plaque on the inside of the coronary arteries blocking the blood flow to the heart causing it to damage the heart muscle. When a heart attack occurs, it creates permanent damage killing a portion of the heart. If the heart cannot effectively pump blood to the body, it will reduce the flow, and begin...

  • Blood Flow Through the Heart
    The heart is made up of four chambers, the left and right atria, and the left and right ventricles. “The left and right sides of the heart do not communicate with one another after birth and are separated by a thick interventrical or interatrial septum” (Prater, 2008). The top (atrium) and bottom (ventricle) parts of the heart are separated by a valve, which prevents the backflow of blood. Blood enters the heart through the inferior and superior vena cava carrying deoxygenated blood. The vena...
