- Deoxygenated blood enters the right atrium through three major veins: the superior and inferior vena cava and the coronary sinus. The superior vena cava returns all of the blood to the heart from tissues superior to the heart in the head, neck, arms and upper thorax. Likewise, the inferior vena cava returns blood to the heart from tissues inferior to the heart, including the legs, abdomen and lower thorax.

- The left and right atria lie anterior to the ventricles. They can be seen on either side of the pulmonary trunk and aorta. Find the two superior venae cavae which drain the anterior body regions, and the inferior vena cava which returns blood to the heart from the abdominal region, all of these enter the right atrium.Pulmonary veins from the lungs enter the left atrium. Make a sketch of the heart and label the chambers and major vessels.ontinue to follow the dorsal aorta as it passes through the diaphragm from the thoracic cavity into the abdominal cavity. The aorta runs alongside the inferior (posterior) vena cava. In the abdominal region, you can find several major unpaired branches of the aorta that supply various parts of the digestive tract.

Major Blood Vessels Leading to the Heart: Superior Vena Cava, Inferior Vena Cava & Coronary Sinus Let's review. Your veins drain deoxygenated blood from your body tissues and return it to the heart. Small veins converge to form larger and larger veins, which eventually drain into the venae cavae. The venae cavae empties the deoxygenated blood into the right atrium of the heart. The venae cavae has two divisions.The superior vena cava resembles a drain that leads down into the heart.mall veins converge to form larger and larger veins, which eventually drain into the venae cavae. The venae cavae empties the deoxygenated blood into the right atrium of the heart. The venae cavae has two divisions. The superior vena cava resembles a drain that leads down into the heart.

Inferior Vena Cava Anatomy. The inferior vena cava (IVC, also known as the posterior vena cava) is a large diameter vein that is located posterior to the abdominal cavity and runs alongside of the right side of the vertebral column (thus making it a retroperitoneal structure), with the aorta lying laterally on the left of the IVC.fter circulating through the body systemically, deoxygenated blood returns to the right atrium of the heart through either the superior vena cava, which drains the upper body, or the IVC that drains everything below the diaphragm, including the lower trunk, abdomen, pelvis, and lower limbs.

Right Atrium The auricle is hollow and extends outward from the anterior surface to increase the internal volume of the right atrium. Deoxygenated blood enters the right atrium through three major veins: the superior and inferior vena cava and the coronary sinus. The superior vena cava returns all of the blood to the heart from tissues superior to the heart in the head, neck, arms and upper thorax. Likewise, the inferior vena cava returns blood to the heart from tissues inferior to the heart, including the legs, abdomen and lower thorax.

What is the difference between the superior vena cava an inferior vena cava? The superior vena cava is a large, yet short vein that carries deoxygenated blood from the upper half of the body to the heart's right atrium. The inferior vena cava (or IVC) … is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart. The Vena Cava carrys de oxygenated blood that is returning from the body and into the right atruim of the heart and the Aorta is the largest artery of the body which tr … ansports oxygenated blood to the rest of the body.     Hope this helps.
