The Heart and Blood Vessels The heart is a muscular pump that pushes blood through blood vessels around the body. Essential to life, the heart beats continuously, pumping the equivalent of more than 14,000 litres of blood every day. Blood vessels form the living system of tubes that carry blood both to and from the heart.

- The organs in your body need oxygen to survive. Oxygen is carried through the body by the blood. When the heart beats, it creates pressure that pushes blood through a network of tube-shaped arteries and veins, also known as blood vessels and capillaries.The pressure --- blood pressure --- is the result of two forces.ealthy arteries are made of muscle and a semi-flexible tissue that stretches like elastic when the heart pumps blood through them. The more forcefully that blood pumps, the more the arteries stretch to allow blood to easily flow.

The Heart and Blood Vessels A blood vessel's main function is to transport blood around the body. Blood vessels also play a role in controlling your blood pressure. Blood vessels are found throughout the body. There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins.roups of capillaries within a tissue reunite to form small veins called venules. Venules collect blood from capillaries and drain into veins. Veins are the blood vessels that carry blood back to the heart.

This constant circulation of blood keeps us alive. Your blood vessels also play a part in the regulation of your blood pressure. Certain chemicals in the body can cause our blood vessels either to contract or dilate.

Thread: why does alcohol dilate blood vessels? Simply the heart, a big muscle, is connected to a series of tubes, the arteries and the veins, which carry blood to the various parts of the body. Arteries carry the blood away from the heart, while veins bring blood back to the heart. The arteries are connected to the veins via very small vessels called capillaries. Electrical and chemical signals to the heart cause it to pump the blood into the arteries. Further, a number factors can cause the blood vessels to expand (dilate) or contract. In doing so they can increase or decrease the amount of effort the heart needs to put forth to deliver the blood.

Blood Vessels (Artery, Vein) Structure, Function, Inflammation Functions of the Blood Vessels. 1  Arteries carry oxygenated and nutrient-rich blood to the body’s tissues from the heart. 2  Dilatation and constriction of the arteries can alter blood pressure and cardiac output. 3  Veins carry deoxygenated blood and wastes from the tissues to the liver and heart.

What do capillaries do? Capillaries are tiny blood vessels connecting the small arteries (arterioles) to the small veins (venules). The blood vessels carry oxygen and nutrients to all the individual cells in the body.apillaries are the blood vessels that lead from the arterioles to the individual cells, and from the cells back to the venules. Capillaries have very thin walls with holes in them, so fluid and small molecules like sugar and waste can move in and out.

How the Heart Works 1 Capillaries. 2  These are small, thin blood vessels that connect the arteries and the veins. 3  Their thin walls allow oxygen, nutrients, carbon dioxide, and other waste products to pass to and from our organ's cells. Veins. 2  These are blood vessels that take blood back to the heart; this blood has lower oxygen content and is rich in waste products that are to be excreted or removed from the body. 3  Veins become larger and larger as they get closer to the heart.

Blood vessels Blood vessels. organs of the cardiovascular system that form a closed circuit of tubes that carries blood from the heart to the body cells and back again. They are arteries, arterioles, capillaries, venules, and veins.hey have a single layer of epithelial cells. Walls are semipermeable, and substances in blood are exchanged for substances in the tissue fluid surrounding the cells. Provide the vital function of exchanging gases, nutrients and metabolic by-products between blood and tissue fluid.

How the Heart Works 1 Arteries carry oxygen-rich blood away from the heart to all of the body's tissues. 2  They branch several times, becoming smaller and smaller as they carry blood further from the heart and into organs. 3  Capillaries. 4  These are small, thin blood vessels that connect the arteries and the veins.

Cardiovascular System Anatomy Blood vessels are the body’s highways that allow blood to flow quickly and efficiently from the heart to every region of the body and back again. The size of blood vessels corresponds with the amount of blood that passes through the vessel.he right side of the heart receives deoxygenated blood from the systemic veins and pumps it to the lungs for oxygenation. The left side of the heart receives oxygenated blood from the lungs and pumps it through the systemic arteries to the tissues of the body.

- There are three main types of blood vessels: 1  arteries take blood away from the heart to the body organs and tissues. 2  capillaries are tiny, thin-walled vessels which form a network to take blood through the organsand tissues. 3  veins collect blood from the capillaries in the body and return the blood to the heart.rteries, veins and capillaries. There are three main types of blood vessels: 1  arteries take blood away from the heart to the body organs and tissues. 2  The artery wall is thick and muscular so it can withstand the high pressure of the blood being pumped directly from the heart.

Exam 4: heart, blood, blood vessels Arteries, Veins, and Capillaries. The blood from the heart is carried through the body by a complex network of blood vessels. Arteries take blood away from the heart. The main artery is the aorta that branches into other major arteries, which take blood to different limbs and organs.

How Does Diabetes Affect Blood Vessels? Blood vessels are like a network of pipelines in your body. This network helps transport blood to all body parts, which in turn delivers oxygen and other nutrients like glucose to the body’s cells. Your body has three main types of vessels: arteries, veins, and capillaries.

Support the Vasculitis Foundation These include arteries, veins, and capillaries. Arteries carry blood from your heart to your body's organs. Veins carry blood from your organs and limbs back to your heart. Capillaries connect the small arteries and veins. If a blood vessel is inflamed, it can narrow or close off.This limits or prevents blood flow through the vessel.Rarely, the blood vessel will stretch and weaken, causing it to bulge.This bulge is known as an aneurysm (AN-u-rism).apillaries connect the small arteries and veins.

Heart & Blood Vessels: How Does Blood Travel Through Your Body As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body.rteries. The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. 1  Arteries begin with the aorta, the large artery leaving the heart. 2  They carry oxygen-rich blood away from the heart to all of the body's tissues.

Blood Vessels: Arteries, Capillaries & More Because arteries are the first vessels that the heart pumps blood through, they experience the highest blood pressure, so they have thick elastic walls to withstand the high pressures. These large arteries expand when the pressure of the blood rises and then recoil when the heart relaxes between beats to provide a smooth flow of blood through your body.

- There are three types of blood vessels: arteries, veins and capillaries. Nutrients are transported throughout your body through your blood via capillaries, tiny blood vessels that connect arteries to veins. Nutrients, oxygen and wastes all pass in and out of your blood through the capillary walls.

- The blood vessels of the body (arteries, capillaries, and veins) make up a closed system of tubes that carry blood from the heart to tissues all over the body and then back to the heart. Arteries carry blood away from the heart, while veins carry blood toward the heart.

Cardiovascular System Anatomy Blood vessels are the body’s highways that allow blood to flow quickly and efficiently from the heart to every region of the body and back again. The size of blood vessels corresponds with the amount of blood that passes through the vessel. All blood vessels contain a hollow area called the lumen through which blood is able to flow.
