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 cava

Mitral Valve aka Bicuspid Valve Human Anatomy & Physiology II The left atrioventricular valve‚ with two cusps‚ is called the mitral valve because it resembles the two-sided bishops miter or hat. It is sometimes called the biscuspid valve. (Marieb & Hoehn‚ 2007). This valve separates the left atrium of the heart from the left ventricle of the heart. It prevents the back flow of oxygenated blood to the pulmonary circuit. Heart valves are simple devices‚ and the heart – like any

The septum form is that ist a wall that divides the left side of the heart from the right side. This keeps the deoxygenated blood from mixing with the oxygenated blood. With the septum having the function of being like a wall it allows it to keep its function of being a barrier between the left and right side of the heart. Respiratory The lungs form is pretty much a sac that is like a balloon. It is flexible in order to inflate and deflate. The lung being like a balloon and flexible allows it to

Normally‚ the heart is divided into four chambers‚ and there is one valve on each side of the heart. The chambers on the right side of the heart receive blood from the body and pump it to the lungs where the blood gets oxygen. The chambers on the left side of the heart get the oxygen-rich blood from the lungs and pump it back out to the body. In CAVC‚ the blood in the chambers mix‚ and the heart valve may not close tightly. This makes the heart work much harder than normal. CVAC is a problem that

and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right ventricle pumps deoxygenated blood to the lungs for gas exchange. At the same time‚ oxygenated blood that has come from the lungs to the left side

artery‚ arise from the right ventricle. Normally‚ the aorta arises from the left ventricle where it receives oxygen-rich blood that is sent to the rest of the body. In contrast‚ the pulmonary artery normally exits from the right ventricle and carries oxygen-poor blood from the heart to the lungs for oxygenation. In addition to DORV‚ affected infants usually tend to have a hole in the muscular wall that separates the left ventricle from the right. This condition is referred to as a ventricular septal
