The spleen, the largest lymphatic organ residing in the body, varies in regards to volume and figure. It is commonly around four inches in length, and its shape resembles a fist (“The Spleen” 1). Its structural anatomy contains an upper and lower pole, hilum, diaphragmatic surface and visceral surface. It is located on the left side of the body in the upper left quadrant of the abdomen, and is suspended in the greater omentum. It is connected to the stomach’s greater curvature, and to the left kidney by the gastrosplenic ligament and splenorenal ligament respectively (Gilroy 152). Most frequently, in adults, the spleen lies posterior to the stomach as well as alongside and inferior to the diaphragm. The spleen lies to the left of the…show more content…
The arterial supply continues into the right ventricle via the tricuspid valve, which shuts when the right ventricle is full, to prevent backflow. Following atrioventricular contraction, from the right ventricle, the pulmonary semilunar valve grants its passage into the the pulmonary trunk, and immediately following, traverses into the left and right pulmonary arteries. From here, the deoxygenated blood is sent to both of the lungs. The blood continues its pathway into the minuscule capillary vessels that reside in the lungs. Here, oxygen exchange occurs. Air travels from the alveoli in the alveolar sacs, through the capillary wall, and lastly into the blood. Simultaneously, carbon dioxide leaves the blood and enters the same air sacs to which it just gained its oxygenation. Once the blood is filtered, it returns to the left atrium of the heart via the left and right pulmonary veins. Next, the blood carries on through the left bicuspid valve. This valve also shuts once the left ventricle is full, meanwhile keeping the blood from flowing backward once the ventricles contract. Blood makes its grand exit through the aortic semilunar valve, and finally exits by way of the ascending aorta (Drake
