Choose A, B, C or D as your solution.
The correct answer is A. The superior vena cava is the vein that carries deoxygenated blood from the upper half of the body to the heart into its right atrium. The aorta is the largest and longest of the arteries of the human body that transports oxygenated blood directly from the left ventricle to all other organs and tissues in the body. The hepatic portal vein is the major vein that transports blood from the digestive organs into the liver. The carotid artery is one of two types of arteries (the other being vertebral) that feed blood from the heart and into the head/ brain area. Answers and Explanations No passage MCAT
