Circulatory System Functions Parts Facts Britannica Now that we understand the structure and function of the heart, which is to pump blood all around the body, what is the blood traveling around in exactly? th. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. these layers surround the lumen, the hollow interior through which blood flows. 2. oxygenated blood flows away from the heart through arteries. the left ventricle of the heart pumps oxygenated blood into the aorta.
Blood Vessel Definition Anatomy Function Types Britannica The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it. your heart pumps blood to the body through a network of arteries and veins (blood vessels). The circulatory system, also called cardiovascular system, is a vital organ system that delivers essential substances to all cells for basic functions to occur. also commonly known as the cardiovascular system, is a network composed of the heart as a centralised pump, blood vessels that distribute blood throughout the body, and the blood itself. 20.1: structure and function of blood vessels. blood is carried through the body via blood vessels. an artery is a blood vessel that carries blood away from the heart, where it branches into ever smaller vessels. eventually, the smallest arteries, vessels called arterioles, further branch into tiny capillaries, where nutrients and wastes are. Figure 18.2.2 18.2. 2: structure of blood vessels. (a) arteries and (b) veins share the same general features, but the walls of arteries are much thicker because of the higher pressure of the blood that flows through them. (c) a micrograph shows a similarly sized artery and vein.

Together, the heart vessels and blood vessels form your circulatory system. your body contains about 60,000 miles of blood vessels. there are three types of blood vessels: arteries carry blood away from your heart. veins carry blood back toward your heart. capillaries, the smallest blood vessels, connect arteries and veins. The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. it consists of the heart and the blood vessels running through the entire body. the arteries carry blood away from the heart; the veins carry it back to the heart. the system of blood vessels resembles a tree: the “trunk” – the main artery (aorta) – branches into large arteries.
