- Capillaries: Capillaries are the smallest of blood vessels. They serve to distribute oxygenated blood from arteries to the tissues of the body and to feed deoxygenated blood from the tissues back into the veins. The capillaries are thus a central component in the circulatory system, essentially between the arteries and the veins.

- The function of veins, arteries and capillaries are reflected in their structure. The walls of the capillaries are relatively thin and made of flat endothelial cells to facilitate exchange of gases, nutrients, and waste between the blood and the fluid surrounding the cells.Arteries, by contrast, have thick, strong walls to withstand the high speed and pressure of blood pumped from the heart.owever, for larger animals, the exchange of gases and nutrients is accomplished through specialized systems for circulation and gas exchange. Humans and other vertebrates have a closed circulatory system where blood is confined to the heart and blood vessels.

- Arterioles feed oxygenated blood to the capillaries. The AORTA is the largest artery in the body, taking blood from the heart, branching into other arteries that send oxygenated blood to the rest of the body. CAPILLARIES. distribute the nutrients and oxygen to the body's tissues and remove deoxygenated blood and waste.very small veins) merge into VEINS which carry blood back to the heart. The vein walls are similar to arteries but thinner and less elastic. Veins carry deoxygenated blood towards the lungs where oxygen is received via the pulmonary capillaries. The PULMONARY Veins then carries this oxygenated blood back to the heart.

- A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins.apillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue). Oxygen, carbon dioxide, nutrients, wastes, and fluids are exchanged through the thin walls of the capillaries. Once the blood leaves the capillaries it is returned to the heart via the veins.

The Heart and Blood Vessels Arterioles are the smallest arteries in the body. They deliver blood to capillaries. Arterioles are also capable of constricting or dilating and, by doing this, they control how much blood enters the capillaries. Capillaries are tiny vessels that connect arterioles to venules.lood 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. Arteries carry blood away from the heart to other organs.

- There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.here is a layer of muscle surrounding the arteries and the veins which help contract and expand the vessels. This creates enough pressure for blood to be pumped around the body. Blood vessels are part of the circulatory system, together with the heart and the blood.

How are the structures and functions of arteries capillaries and veins similar? Arteries are thick walled,it is so because they carry blood with high pressure,so that the walls may not collapse.Veins are blue in color as the color of their impure blood. Their thickness is medium.On the other hand capillaries have very thin permeable walls because a lot of materials are transferred at their walls.he structures of arteries, capillaries, and veins are all different, because of their different functions. The only way that they are similar is because they are hollow, and … have some elasticity.

The Heart and Blood Vessels For this reason, capillaries are known as exchange vessels. Groups 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.They may contain valves which stop blood flowing away from the heart. 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.

THE CIRCULATORY SYSTEM Veins are blood vessels that transport blood to the heart. With the exception of the pulmonary vein, they carry deoxygenated blood. They have three layers in their walls as well. The main difference is that there is less smooth muscle in the middle layer and less connective tissue in the outer layer.escribe the 4 functions of the cardiovascular system. 1. Contractions of the heart generate blood pressure which moves blood through the blood vessels. 2. Blood vessels transport blood from the heart to the arteries, capillaries, and veins. Blood then returns to the heart. 3. Gas exchange occurs in the capillaries.

Contents: Veins and Arteries Types of arteries and veins. There are two types of arteries in the body: Pulmonary and systemic. The pulmonary artery carries deoxygenated blood from the heart, to the lungs, for purification while the systemic arteries form a network of arteries that carry oxygenated blood from the heart to other parts of the body.hey are tiny branches of arteries that lead to capillaries and help maintain the pressure and blood flow in the body. Venous valves prevent blood from flowing in the opposite direction. Connective tissues make up the outermost layer of a vein which is also known as-tunica adventitia or tunica externa.

Classification & Structure of Blood Vessels Capillaries. 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).The primary function of capillaries is the exchange of materials between the blood and tissue cells.ystemic arteries transport oxygenated blood from the left ventricle to the body tissues. Blood is pumped from the ventricles into large elastic arteries that branch repeatedly into smaller and smaller arteries until the branching results in microscopic arteries called arterioles.

What are main parts of the circulatory system and their functions? 1 Arteries take oxygen-rich blood away from your heart.  2 Veins take blood back toward your heart.  Capillaries are very tiny blood vessels that form a connection between arteries and veins. The capillary walls facilitate the transfer of oxygen, nutrients and wastes in and out of your body.

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.
