are veins and arteries connected?
483011
Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.

Blood vessels. Because the outlines of the large vessels near your heart — the aorta and pulmonary arteries and veins — are visible on X-rays, they may reveal aortic aneurysms, other blood vessel problems or congenital heart disease.

Veins are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.

Nerves belong to the nervous system, but, veins are a component of the circulation system.

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.

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.)

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.

For example, the heart and the blood vessels make up the cardiovascular system. They work together to circulate the blood, bringing oxygen and nutrients to cells throughout the body and carrying away carbon dioxide and metabolic wastes.

Arteries usually carry oxygenated blood and veins usually carry deoxygenated blood. This is true most of the time. However, the pulmonary arteries and veins are an exception to this rule. Pulmonary veins carry oxygenated blood towards the heart and the pulmonary arteries carry deoxygenated blood away from the heart.

The pulmonary veins transport oxygenated blood back to the heart from the lungs, while the pulmonary arteries move deoxygenated blood from the heart to the lungs.) As the vessels that are closest to the heart, arteries must contend with intense physical pressure from the blood moving forcibly through them.

About the Heart and Circulatory System. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries.

Blood is drawn from the veins and not the arteries for a couple of reasons. Firstly, the veins have a much lower pressure than the arteries, and...

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.

Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs.

Located throughout the body, arteries transport nutrient-rich, oxygenated blood to organs and tissues. Arteries are more muscular and have smaller, rounder lumens (internal spaces) than veins. The artery lumen has a wavy endothelium, or inner lining, due to the configuration of elastic tissue beneath it.

Arteries carry blood from the heart to the rest of the body, whereas veins carry blood from the rest of the body back to the heart. ... Arteries have a thick elastic muscle layer, whereas the muscle layer for veins is much thinner.

Explanation: Arteries carry blood under high pressure from the heart to the organs and tissues. Their walls are generally thicker than veins. ... Capillaries are the link between arteries and veins and are very small, Tissue fluid sometimes seeps out and is recollected by the lymphatic system and returned to the veins.
