what is the difference from vein and artery?
19824
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.

Superficial vein is a vein that is close to the surface of the body. This differs from deep veins that are far from the surface. Superficial veins are not paired with an artery, unlike the deep veins, which typically have an artery with the same name close by.

Arteries take blood away from the heart to the organs and other body tissues. Arteries have a narrow internal diameter and thick muscular walls. This allows them to carry blood that is at a high pressure. ... Veins carry blood under low pressure from the capillaries and return the blood to the heart.

Veins are generally larger in diameter, carry more blood volume and have thinner walls in proportion to their lumen. Arteries are smaller, have thicker walls in proportion to their lumen and carry blood under higher pressure than veins.

Arteries experience a pressure wave as blood is pumped from the heart. This can be felt as a "pulse." Because of this pressure the walls of arteries are much thicker than those of veins. In addition, the tunica media is much thicker in arteries than in veins.

Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. ... These vessels are channels that distribute blood to the body.

Veins. Veins carry blood toward the heart. ... This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries. Because the walls of the veins are thinner and less rigid than arteries, veins can hold more blood.

Arteries have a great deal more smooth muscle within their walls than veins, thus their greater wall thickness. This is because they have to carry pumped blood away from the heart to all the organs and tissues that need the oxygenated blood. The endothelial lining of each is similar.

Although arterial and venous insufficiency share many of the same characteristics and symptoms, the two conditions are actually quite different. Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries.

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. Similarly, the veins are distinguishable from arteries and arterioles, because their walls are much thinner, compared to the diameter of their lumen.

Arteries are blood vessels that carry blood away from the heart. This blood is normally oxygenated, with the exception of blood in the pulmonary artery. Arteries typically have a thicker tunica media than veins, containing more smooth muscle cells and elastic tissue.

Arterial blood is the oxygenated blood in the circulatory system found in the pulmonary vein, the left chambers of the heart, and in the arteries. It is bright red in color, while venous blood is dark red in color (but looks purple through the translucent skin).

Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. ... They're part of two closed systems of tubes that begin and end at the heart.

As in arteries, there are tiny vessels called vasa vasorum that supply blood to the walls of the veins and other minute vessels that carry blood away. Veins are more numerous than arteries and have thinner walls owing to lower blood pressure. They tend to parallel the course of arteries.

The term vascular is used in the study of human medicine, but the term avascular is generally usually used in place of non-vascular in this field. Vascular tissues in the human body have blood vessels like veins, arteries and capillaries, while avascular tissues do not.

Veins bring blood cells to the heart, where they can pick up oxygen that's been brought in by the lungs. Arteries take blood cells away from the heart, where they can deliver that oxygen to the rest of the body. The Aorta is the first and largest part of the artery system.

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. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.)
