Six large veins carry blood to the heart: the superior vena cava and inferior vena cava carry blood from the body to the right atrium, and four pulmonary veins carry blood from the lungs to the left atrium. 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.

Why must a pressure difference exist between the aorta and the vena cavae?
Pressure must move from one area to another, otherwise no flow will occur. In the case of the human heart, pressure pushes blood from the aorta, through arteries, arterioles, capillaries, venuoles, and finally veins, to the vena cavae, where the blood goes back into the heart to be re-oxygenated.
What does a superior aorta do?
The Superior Aorta Is A Vein, Also Known As The Superior Vena Cavae Which Allows Dirty, De- Oxygenated Blood To Enter The Heart That Has Passed Through Other Organs.
What is the body's largest vein?
The vena cavae, which returns blood from the bottom half of your body back to your heart.
What is the main vien in your body?
The main vein in the body is the Vena Cavae vein. The inferior vena cavae vein carries blood from the legs and stomach to the heart. The superior vena cavae carries blood from the arms and head to the right atrium of the heart.
What vessel returns blood from the abdomen and legs to the heart?
Inferior vena cavae
Compare the thickness of the walls of the superior and inferior vena cava and the aorta?
The aorta has significantly thicker walls than the superior and inferior venae cavae as the aorta is an artery that must respond to significant intraluminal pressures whereas the venae cavae are veins that have minimal intraluminal pressure.
What emptys blood from the body into the right side of the heart?
The superior and inferior vena cavae.
What empties blood from the body into the right side of the heart?
The superior and inferior vena cavae.
Carry blood back to the heart?
The superior and inferior vena cavae carry blood back to the heart.
What are 2 major veins that pump blood into the heart?
Since the pig is a quadruped (trots around on all fours) the blood vessels are named the ANTERIOR and POSTERIOR vena cavae, rather than the superior and inferior vena cavae which are used to describe the same veins in upright bipeds like humans
What happens at the vena cavae?
The vena cavae collect blood from the systemic circulation. They deliver this deoxygenated blood to the right atrium.
Which three blood vessels carries blood at the highest pressure?
Blood pressure is highest at the Aorta. BP progressively decreases as it enters arterioles, capillaries, venules, then increases upon reaching the vena cavae. So basically it's the Aorta, and the Inferior and Superior Vena Cava.
