The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
Arterioles are considered as the primary resistance vessels as they distribute blood flow into capillary beds. Arterioles provide approximately 80% of the total resistance to blood flow through the body.
Arteries are blood vessels. Most carry oxygen-rich blood away from the heart and deliver it to various organs and tissues. Arteries are a part of the circulatory system, along with the heart and other blood vessels. The circulatory, or cardiovascular, system is essential for transporting blood around the body.
