Blood Vessels Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart.Veins carry the blood back to the heart.They’re similar to arteries but not as strong or as thick. Unlike arteries, veins contain valves that ensure blood flows in only one direction.he capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart.

Describe the function of arteries, vein,and capillaries in the circulatory system? Capillaries are very thin, fragile blood vessels that receive oxygen-rich blood from arteries, exchange oxygen and carbon dioxide and then deliver the waste-rich blood to the veins. Capillaries are only one epithelial cell thick and blood can only flow through them in a single file.

Do capillaries have valves if no why? Answers.com® is making the world better one answer at a time. Capillaries are very small blood vessels which act as the transporting medium between the oxygenated blood in the arteries (excluding the pulmonary) and the deoxygenated blood in the veins.

- A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active.apillary Size. Capillaries are so small that red blood cells can only travel through them in single file. Capillaries measure in size from about 5-10 microns in diameter. Capillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue).

- The capillary also allows waste from the metabolizing cell to diffuse from the tissue spaces into the capillaries for transport by the blood to the organs of excretion. The capillaries are called exchange vessels because they allow for an exchange of nutrients and waste. 6 people found this useful.

What do arteries,veins, and capillaries do? Arteries carry blood away from the heart, while veins carry blood towards the heart. Capillaries carry blood from arteries to veins. Arteries generally carry oxygenated blood from the heart to the tissues and organs during the systolic heartbeat cycle. They are under high pressure. (the only exception is the pulmonary arteries which carries deoxygenated blood from the heart to the lungs).

Describe the function of arteries, vein,and capillaries in the circulatory system? Veins carry oxygen depleted blood back to your heart. Capillaries are very small veins or arteries. They are small enough that the oxygen can diffuse across the capillary wall into the tissue, and the carbon dioxide can diffuse from the tissue back into the blood.Capillaries are the structure where this gas exchange takes place.rteries are muscular blood vessels that carry oxygenated blood away from the heart (except the pulmonary and umbilical arteries). Arteries carry oxygen-rich blood at high pressure, so they are tough on the outside and smooth on the inside.

Understanding Capillary Fluid Exchange A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active.hese structures are located between arterioles and capillaries and contain muscle fibers that allow them to contract. When the sphincters are open, blood flows freely to the capillary beds of body tissue. When the sphincters are closed, blood is not allowed to flow through the capillary beds.

- The capillaries are part of the circulation system. From the heart, blood is pumped to the arteries branching into arterioles and then into capillaries. These capillaries service the various organs of the body. From these organs, capillaries widen to venules and then veins which bring the blood back to the heart.

Classification & Structure of Blood Vessels Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).

One place where they can be easily seen (no pun intended!) from the outside is on the whites of the eyes.Capillaries are found in every square inch of the body, from the skin to the deepest tissues in the body's cavities.apillary Function and Structure. Capillaries deliver nutrients and oxygen to tissues and remove the byproducts of cellular reactions, such as carbon dioxide and water.

What job does capillaries do? Capillaries Tiny blood vessels connecting arteries to veins. These  blood vessels carry oxygen and nutrients to individual cells.  Capillaries are the smallest blood vessels … in the body, and have  walls only one or two cells thick.hen blood cells enter the capillaries, the oxygen and nutrients which are stored in hemoglobin in the blood diffuse into the body. The exhausted blood cells then enter back into larger vessels to join the bloodstream once again. The cycle goes something like this: Many people confuse veins with arteries.

What do capillaries do? Capillaries are the blood vessels that lead from the arterioles to the individual cells, and from the cells back to the venules. <br /> <br /> Capillaries have very thin walls with holes in them, so fluid and small molecules like sugar and waste can move in and out.

Understanding Capillary Fluid Exchange Capillaries are where fluids, gasses, nutrients, and wastes are exchanged between the blood and body tissues by diffusion. Capillary walls contain small pores that allow certain substances to pass into and out of the blood vessel. Gasses, nutrients, and wastes are also exchanged at this point. 2  On the venule end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. 3  The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
