Arteries have thick, elastic muscle layer that can handle high pressure of the blood flow. Veins contain thin, elastic muscle layer with semilunar valves that prevent the blood from flowing in the opposite direction. Arteries have a high resistance while Veins have high capacitance.

∙ 14y agoArteries have muscular walls to regulate their size, and the blood is under pressure from the hearts pumping. Veins rely on muscular movement by the person to move blood back to the heart. Veins also have little valves in them to prevent blood from going the wrong way.

∙ 9y agoFunction:
Arteries carry oxygenated blood away from the heart towards the other organs of the body (with the exception of the pulmonary artery that carry oxygenated blood to the heart). Veins carry deoxygenated blood to the heart (with with the exception of the pulmonary veing that carry deoxygenated blood away the heart towards the lungs).
Structure:
Arteries are larger than veins. All vessels have an epithellial layer. Arteries and veins have an additional outer layer of connective tissue with elastic fibers enables the vessels to stretch and recoil. The middle layer consists mainly of smooth muscle. Both layers are thick and sturdier in arteries, providing the strength and elasticity to accommodate the rapid flow and high pressure of blood pumped by the heart. Arteries can also regulate blood flow by constricting or relaxing their smooth muscle layer. Thinner-walled veins convey blood back to the heart at low velocity and pressure. Within large veins, flaps of tissues act as one-way valves.
Hope it helps!!
Veins carry the blood to the heart, arteries carry the blood away from the heart and capillaries get it to the really hard places like your toes or fingertips... i hope this is right or ive failed my exam

How does the structure of each mayor type of vessel differ from the other type?
The major blood vessels include the Arteries which have thicker walls compare to veins and blood flows in pulse, Veins which have thicker walls compared to capillaries and have vales , and lastly Capillaries which are smaller compared to veins and arteries and do not have valves.
The differences of the structure of an artery a veins a capillary?
Arteries carry blood away from the heart, veins carry blood to the heart, and capillaries branch off of arteries and veins. Capillaries are essentially min-arteries and min-veins.
How is the structure of veins and arteries related to their fuction?
compare and contrast the structure of a vein and artery
How do you lymphatic vessels and veins differ in structure?
Lymphatics resemble veins in structure but have thinner walls and more valves.
Do arteries have the same structure but much thicker walls than veins?
yes
What is the comparison between the structure of the vein and the artery?
the veins are narrower and the arteries are thicker because the arteries should have to withstand a great force
Name three blood vessels?
the three blood vessels are the Veins capillaries Arteries the arteries.
What do arteries and veins drain?
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
What is the difference between the blood in the arteries and the blood in the veins?
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
What material surrounds veins and arteries?
Cellulose is what surronds veins and arteries.
Contrast the structure of veins and arteries for thickness of muscle and elastic tissue?
The more pressure it uses, the thicker the walls will be. Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.
How does the direction blood travels in arteries and veins differ?
the blood in the arteries in oxygenated and is flowing away from the heart throughout the body tyo give your cells oxygen. the blood in the veins has had its oxygen depleted by your cells and is travelling back to the heart and lungs to get more oxygen
