Name:Instructor:Course:Date:THE HUMAN HEARTIntroductionThe heart is usually considered one of the most significant organs in the human body. More or less, it is a pump comprised of materials that assist the functions of the human bodies and eliminates the waste products that are not required in the system (Tortora, 12). The heart is required to pump throughout a lifetime of human beings because if ever it stops to pump blood, there is a great likelihood of the body shutting down and even resulting to death after a very short time. The heart performs a very crucial role and thus is worth discovering its functions through the structural components and chronic conditions that may affect it. The Structural Components and FunctionsHeart`s walls are consistent of three layers and the cavity is usually split into four fractions. Two chambers are found at the upper part of the heart and are namely, left and the right atria, while the chambers on the lower part are called left and right ventricles. The right upper chamber, which is the Right Atrium, takes delivery of the blood from the lower and upper body via the superior vena cava as well as the inferior vena cava in that order. In addition, it receives blood as well from the heart muscle via the coronary sinus (Little, William, 10). Between the two atria, the right atrium is the larger and bears very thin walls. The right atrium then opens up to the right ventricle via the so called right atrioventicular valve also known as tricuspid that specifically permits the blood in flowing into the ventricles from the atria though not in the direction of reverse. The right ventricle pushes the blood into the lungs so that it can be reoxygenated. In addition, the left atrium takes delivery of the blood from the lungs through the four known pulmonary veins (Al Suwaidi, Jassim, 15). The left atrium as early stated is minor than the right atrium but its walls are usually thicker. The valve that exist between...
