  1. My partner’s subject was “The structure and function of the heart and Coarctation of the Aorta” with a step-by-step journey traveling through the heart’s functions. Starting with the vena cava which is a vein that separates into superior and inferior vena cava returns oxygenated blood back to the heart. Going into the atrium, which the vena cava empties into. It is here where the heart receives the systematic blood returning to the heart. The tricuspid valve prevents backflow connected by the chordae tendineae which is the connection between valves and papillary muscles. This will give us the blood pressure needed to reach the pulmonary and circulatory systems. The left and right lungs receive blood for oxygen from the left and right pulmonary artery. Prevented regurgitation thanks to the pulmonary valve. After the lungs receive the blood, is it oxidized. The blood is brought back through the pulmonary veins to the circulatory circuit. The pulmonary veins empty into the left atrium with oxygenated blood passing through the mitral valve. After we pass the bicuspid valve we have the the left ventricle which has a wall much thicker than the right to withstand the pressure needed to send blood through the systemic circulatory circuit. The rest of the body gets supplied with oxygenated-rich blood via the aorta. A complication with the aorta can be know as COA which is the concretion of the aorta with a narrowing of the aorta. Causing increased blood pressure in the upper body and a lower blood pressure in the lower body. This can be congenital and can be corrected by a number of things including a balloon with or without a stint. This congenital heart defects is just one of the many heart defects infants can face.
