- Actually, arteries carry oxygen-rich blood to the body, whereas veins carry oxygen-poor blood back to the heart. The only exception to this rule is the Pulmonary Artery, which carries oxygen-poor blood to the lungs.It is called an artery because it carries blood from the heart instead of towards it.he blood in the pulmonary artery is oxygen-poor. yes all the arteries carry oxygenated blood except pulmonary artery which carry de … oxigenated blood from the right ventricle of the heart towards the lungs.. I don't know what arties are, but arteries carry oxygen-rich blood while veins carry CO2 rich blood. Answered.

What is the difference between an artery and a vein? Arteries carry blood (with oxygen) from your heart out to your body, while veins carry blood (without oxygen) from your body to your heart. Arteries are strong, flexible blood vessels that are able to expand (get bigger) and contract (get smaller).They expand as your heart beats, and contract between heartbeats.he chief difference between arteries and veins is the job that they do. Arteries carry oxygenated blood away from the heart to the body, and veins carry oxygen-poor blood back from the body to the heart. Your body also contains other, smaller blood vessels.

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.

Circulatory System Venules and Veins. To return blood to the heart, there is a series of venules, veins, and muscular veins. Venules have much larger lumina and thinner walls than corresponding arterioles.n a section that has both arteries and veins, the artery and veins are very easy to tell apart. The thickness of the walls of the veins is much less, compared to the lumen, and the lumen is often collapsed as shown here.

Contents: Veins and Arteries There are two types of blood vessels in the circulatory system of the body: arteries that carry oxygenated blood from the heart to various parts of the body and veins that carry blood towards the heart for purification.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.

PBS Unit 4 How does the structure of arteries and veins relate to their functions? Arteries - transports oxygenated blood from the heart (except in pulmonary artery which contains deoxygenated blood). Arteries have: -thick muscular wall. -much elastic tissue. -small lumen relative to diameter. -not permeable. -valves in pulmonary artery and Aorta only. -blood under high pressure (10-16kPa)

2/5 â Describe & Compare/Contrast: Xylem/Phloem & Veins/Arteries The veins and arteries have a few differences from the xylem and phloem. The xylem and phloem carry water and nutrients throughout a plant while the veins and arteries carry blood in a body. The xylem and phloem transport things up and down and veins and arteries carry blood to and from the heart.

- Blood Vessels There are five general classes of blood vessels in the cardio-vascular system: arteries, arterioles, capillaries, venules, and veins (see Figure 5–5). Arteries are elastic vessels that are very strong, able to carry blood away from the heart under high pressure.rteries: Elastic vessels able to carry blood away from the heart under high pressure. Arterioles: Subdivisions of arteries; they are thinner and have muscles that are innervated by the sympathetic nervous system. Atria: The upper chambers of the heart; they receive blood returning to the heart.

- Arteries are the efferent vessels of the cardiovascular system — they carry blood away from the heart. 4. Veins are the afferent vessels, carrying blood back to the heart. 5. Capillaries are microscopic, thin-walled vessels that connect the arteries to the veins and allows for. exchange of material and gas exchange.

- 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.

Why are the walls of the left ventricle thicker than the right ventricle of the heart? The left ventricle is more muscular than the right ventricle because it pumps the blood at a higher pressure. Just as any other muscle in your body... If you work one and not …the other- the one you work gets bigger and the opposing won't.

- Arteries are brighter red and narrower than veins. Actually, the retinal arteries lack a muscular coat, so they are more correctly called arterioles. The vessels you see here supply and drain the inner retina, including the retinal ganglion cells and their axons and the bipolar cells.he retinal arteries and veins emerge from the nasal side (left) of the optic disc. Vessels directed temporally have an arching course; those directed nasally have a radial course.

Chapter 19, blood vessels • In the elastic artery, elastin forms most of the wall of the tunica media. In the muscular artery, the tunica media is composed mainly of smooth muscle. • Muscular arteries deliver blood to specific body organs. • They have relatively more smooth muscle and less elastin than elastic arteries in the tunica media.

The Structure and Function Of Arteries, Veins and Capillaries. In conclusion, the arteries carry oxygenated blood away from the heart, and due to the high pressure of this blood the arteries have thick wall, which contain many muscle fibres. The veins carry deoxygenated blood to the heart and because blood is of a lower pressure, have thinner walls consisting of less muscle fibres. intend to explore the structure and function of arteries, veins and capillaries. When an artery branches into smaller and smaller vessels, eventually the blood vessel is too small to see with the naked eye. At that point, it is called an arteriole. Likewise, a venule is a microscopic vein.

What is the differences and similarities between capillaries, arteries, and viens? All three are types of blood vessels. Arteries carry freshly-oxygenated blood away from the heart and supply it to organs and other parts of the body that need oxygen. Veins carry oxygen-depleted blood back to the heart.Capillaries are tiny blood vessels that branch off from arteries and veins, and that most closely interact with tissue to supply oxygen to them (or carry oxygen-depleted blood away from them).Mark H · 9 years ago.eins carry oxygen-depleted blood back to the heart.

Describe the characteristics of arteries, veins and capillaries that make them suited to their function.? Veins are very similar to arteries in their structure, but differ slightly. Veins have large lumens and relatively thin muscular walls (less smooth muscle, less elastin fibres). In addition, veins have valves to prevent back flow of the deoxygenated blood.

Human Physiology/Print Version Arteries, on the other hand, are classified as systemic (part of the cardiovascular system), pulmonary (carry blood to the lungs), aorta and arterioles. Arteries carry bright red blood as it is oxygenated while veins have the dark red blood. Arteries progressively divide into smaller tubes unlike veins.
