Arteries and Veins Arteries and Veins. As we stated on the previous page, What Is High Blood Pressure , arteries and veins are both part of the circulatory system and carry blood from the heart to the lungs and to all other parts of our bodies. Both are very important in maintaining our blood pressure.Though they both carry blood through our bodies they are very different and are even made of different tissue and perform their own functions in specific ways. Arteries. Arteries carry blood which is full of oxygen away from the heart.Arteries have three layers of tissue-the outside and inside layers are made of a connective tissue which covers the muscular middle layer of smooth muscle, and elastic fibers. These tissues provide a smooth path for our blood to flow through.oth are very important in maintaining our blood pressure.

- Arteries are the blood vessels that carry blood away from the heart. They are responsible for carrying oxygen and other important nutrients out to the body. In this sense, arteries can be thought of as the supply train of the body, bringing in the raw materials that your organs need in order to do their jobs.

- Best Answer: arteries take blood away from the heart (oxygenated), veins take blood back to the heart (deoxygenated). They are separate systems joined together by capillary networks whereby gas exchange occurs.Source(s): HwPal-http://www.hwpal.com/.rteries are like the water pipes in your house. the veins would be the sewer pipes. the capillaries are the sinks where the water comes from the water pipes and goes to the sewer.

- The difference is that an artery brings blood to the body and a vein takes blood to the lungs. Arteries and Veins are part of the circulatory system, where arteries carry the blood from the heart to the organs, and the veins carry it from the organs to the heart again.tructural similarities between artries and veins are 1) The walls of arteries and veins both contain collagen which makes them strong and durable. 2) They both contain elasti … c fibres which allow them to stretch and recoil.

- Arteries carry oxygenated blood away from the heart, to the cells that need them. Veins carry blood containing carbon dioxide back to the heart after the oxygen has been given to the cells. Capillaries are the thinnest arteries and veins.They are only one cell wide. As the blood cell passes through the very thin capillary, the cells on either side are given oxygen and carbon dioxide is taken from them. Therefore, the capillaries connect the arteries and veins.apillaries are smaller extensions of arteries and veins, supplying blood tho the bodies extremities. When the arteries deposit the oxygen and other nutrients through the capillaries, the blood then moves to the veins, which will carry the blood back to the heart.

What is the Difference Between Arteries, Veins, Blood Vessels and Capillaries? Arteries, veins, and capillaries are in fact all forms of blood vessels, just with different shapes and roles in the body. Blood vessels are an integral part of the circulatory system, which transfers oxygen and important components of life around the body and removes waste. Each of the three major types of blood vessels play their own role in this complex system, helping to keep a human body functioning at full strength and health.

Blood Vessels Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don’t require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.nlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don’t require valves because pressure from the heart is so strong that blood is only able to flow in one direction.)

- Veins are a part of the human cardiovascular system. There job is to return blood back to the heart after the blood has circulated through the body by way of the arteries. The … arteries, which carry the blood away from the heart, eventually divide into small capillaries, or tiny blood vessels, which diffuse oxygen originally from the heart into body cells.

Describe the function of arteries, vein,and capillaries in the circulatory system? The arteries are perceived as carrying oxygenated blood to the tissues, while veins carry deoxygenated blood back to the heart. This is true of the systemic circulation, by far the larger of the two circuits of blood in the body, which transports oxygen from the heart to the tissues of the body.owever, in pulmonary circulation, the arteries carry deoxygenated blood from the heart to the lungs, and veins return blood from the lungs to the heart. The difference between veins and arteries is their direction of flow (out of the heart by arteries, returning to the heart for veins), not their oxygen content.

What is the Difference Between Arteries, Veins, Blood Vessels and Capillaries? The arteries are those blood vessels that carry blood away from the heart. This means that, with only two exceptions, arteries are carrying highly oxygenated blood to transport oxygen to the tissue of the body. Arteries are the higher-pressure part of the circulatory system, as they are getting blood from the heart.

What is the difference in structure and function between an artery and a vein? Arteries carry blood away from the heart, e.g aorta and pulmonary artery, arteries are thick, the inside of them is made of epithelial cells as they are smooth, they help blood flow more easily, the middle layer is muscle, these can go along with pulses to help them.eins carry the blood back from the other areas of the body to the heart. Simply put, an artery carries blood out of the heart, and a vein carries blood into the heart. Arteries are under more pressure than veins. Arteries contract to help push blood through whereas blood flow through veins is passive.

How Does Regular Exercise Affect the Arteries & Veins? Arteries and veins carry blood around your body. Arteries take blood away from your heart, delivering it to your organs and muscles. Veins bring blood back to your heart from those same organs and muscles. Your main arteries include the coronary arteries of your heart, the carotid and cerebral arteries of your brain, and the peripheral arteries, which stretch out into your limbs.

Chapter 21: The Cardiovascular System-Blood Vessels and Hemodynamics Why are valves more important in arm veins and leg veins than in neck veins? Valves are more important in arm veins and leg veins than in neck veins because, when you are standing, gravity causes pooling of blood in the veins of the free limbs but aids the flow of blood in neck veins back toward the heart. A person who has liver failure cannot synthesize the normal amount of plasma proteins.

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.eins can be classified as pulmonary veins and systemic veins. The pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart and the Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.

Describe the characteristics of arteries, veins and capillaries that make them suited to their function.? Arteries are blood vessels that carry oxygen-rich blood away from the heart. Veins are blood vessels that carry blood back towards the heart. Capillaries are thin blood vessels that connect arteries to veins.

- Blood is transported through the whole body by a continuum of blood vessels. Arteries are blood vessels that transport blood away from the heart, and veins transport the blood back to the heart. Capillaries carry blood to tissue cells and are the exchange sites of nutrients, gases, wastes, etc. vein is a blood vessel that has a larger lumen, and sometimes veins serve as blood reservoirs or capacitance vessels, containing valves that prevent backflow. This system of vessels in general returns blood to the heart from the periphery (see the image below). Veins: blood flow and valve structure.

Describe two structural differences between an artery and a vein? The walls of veins have three layers of tissues like the arteries but veins are much thinner and less elastic than arteries. 2. Veins have valves that help in the process of returning blood to the heart by preventing blood from flowing reverse.eins carry blood away from the heart, arteries carry blood toward the heart. (except for the pulmonary arteries) Veins have lower pressure flow and are compressible. arteries have higher pressure flow and do not normally compress. Oops!!! I did get that backwards!! Thanks for the correction.
