Quizplus · Accepted Answer

Arterioles are the smallest branches of arteries that control the blood flow to different organs and tissues. They regulate the blood distribution to various parts of the body, including the digestive system. Therefore, blood pumped through the systemic circuit is distributed to lower body regions such as the digestive system by arterioles. Carotid arteries are located in the neck and supply blood to the head and neck. Pulmonary arteries carry deoxygenated blood from the heart to the lungs, while pulmonary veins carry oxygenated blood from the lungs to the heart. The superior vena cava carries deoxygenated blood from the upper part of the body to the heart.
