Right atrium
The right atrium of the heart receives blood from the Inferior vena cava and the Superior vena cava. The blood then passes through the Tricuspid valve and then into the right … ventricle. 3 people found this useful. Two arteries, the pulmonary trunk and the aorta, exit the heart. The pulmonary trunk, arising from the right ventricle, splits into the right and left ventricle, carries blood to the rest of the body. The superior vena cava and inferior vena cava drain systemic venous blood into the posterior wall of the right atrium. The internal wall of the right atrium is composed of a smooth posterior portion (into which the vena cavae and coronary sinus drain) and a ridgelike, muscular anterior portion. The opening of the coronary sinus is located between the right AV orifice and the inferior vena cava orifice. The coronary sinus drains all venous blood from the heart except the blood carried from the anterior cardiac veins. 6 Lay the heart on the dissecting tray, posterior surface up. Locate the inferior vena cava and superior vena cava. 7. Use the scalpel to open the heart chambers: make an incision along the coronal plane, from the superior portion of the left ventricle to the superior portion of the right ventricle. 4 4. Identify the anterior and posterior view of the heart. Anterior (Ventral) View: notice the Posterior (Dorsal) View: notice the anterior interventricular sulcus posterior interventricular sulcus Posterior 4. 5. Distinguish the four chambers of the heart. Lay the heart on the dissecting tray, an Intraoperatively, the anatomy of the heart is viewed from the right side of the supine patient via a median sternotomy incision. The structures initially seen from this perspective include the superior vena cava, right atrium, right ventricle, pulmonary artery, and aorta. The opening of the coronary sinus is located between the right AV orifice and the inferior vena cava orifice. The coronary sinus drains all venous blood from the heart except the blood carried from the anterior cardiac veins. Because the inferior vena cava is located to the right of the midline, drainage of the tributaries is not always symmetrical. On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. On the left, they drain into the renal vein which in turn drains into the inferior vena cava. By contrast, all the lumbar veins and hepatic veins usually drain directly into the inferior vena cava. The inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra. On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. On the left, they drain into the renal vein which in turn drains into the inferior vena cava. By contrast, all the lumbar veins and hepatic veins usually drain directly The anterior vena cava conducts deoxygenated blood from the upper part of the body to the right atrium of the heart. Individuals with anterior vena cava syndrome may develop a bad cough. Surgery may be required to treat a problem involving the anterior vena cava. Another vessel, the posterior vena cava, carries blood from the lower half of the body to the heart. Both vessels rely on the maintenance of steady blood pressure and the pulsations of the heart to force blood through the body and back up The posterior vena cava, also called the caudal vena cava, is the large vein that collects blood from the caudal half of the animal and delivers it to the right atrium. The ca … udal vena cava provides venous drainage to the hind limbs, reproductive tract and digestive tract. In human's ... there ain't none. Two arteries, the pulmonary trunk and the aorta, exit the heart. The pulmonary trunk, arising from the right ventricle, splits into the right and left ventricle, carries blood to the rest of the body. Veins. On the posterior side of the heart there is a groove known as the coronary groove which contains the coronary sinus, which receives blood from the great cardiac vein, the middle cardiac vein, the small cardiac veins, the left marginal vein and the left posterior ventricular veins. The other veins of the heart include the anterior cardiac veins which directly enter the right atrium and the smallest cardiac veins that open into all the chambers of the heart. Structure [edit]. The inferior vena cava is formed by the joining of the left and right common iliac veins and brings collected blood into the right atrium of the heart. It also joins with the azygos vein (which runs on the right side of the vertebral column) and venous plexuses next to the spinal cord. On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. On the left, they drain into the renal vein which in turn drains into the inferior vena cava. By contrast, all the lumbar veins and hepatic veins usually drain directly
