what is the difference between venous and arterial hemorrhage?

In arterial bleeding, the blood pumps or spurts from the wound with each heartbeat. In major venous bleeding, the blood just runs out of the wound at a steady rate.

However, the two blood vessels are quite different from each other in terms of function. One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart.

A regular bruise is more spread out and may not feel like a firm lump. A hematoma usually is not a cause for concern. It is not the same thing as a blood clot in a vein, and it does not cause blood clots. Bruises that do not appear to be caused by an accidental injury may be caused by abuse.

Veins contain a smaller mass of muscle tissue than arteries, and are located in closer proximity to the skin's surface. Arteries transport nutrient-rich blood away from the heart, while veins carry blood back toward the heart.

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.

Just like the arterial system, three layers make up the vein walls. But unlike the arteries, the venous pressure is low. Veins are thin-walled and are less elastic. This feature permits the veins to hold a very high percentage of the blood in circulation.

One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart. Read on to explore what are arteries and veins and the difference between arteries and veins.

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.

Varicose Veins Normally, the valves help blood flow to your heart . When they don't work right, blood pools inside your veins. They swell and become large and rope-like. That's another difference from DVT -- the surface-level clots that come with varicose veins don't usually break free and travel to your lungs.

1. Arteries have a much thicker wall to withstand the high pressure of blood flowing in them, whereas veins have a thinner wall so that they can be pressed flat against adjacent muscles, helping to move the blood. 2. Veins have valves, contrary to arteries, to prevent back-flow of blood flowing in them.

Veins differ from arteries in structure and function. For example, arteries are more muscular than veins, veins are often closer to the skin, and veins contain valves to help keep blood flowing toward the heart, while arteries do not have valves and carry blood away from the heart.

You may have a few minutes of discomfort during or after the test. Collecting blood from an artery typically hurts more than drawing it from a vein. Arteries are deeper than veins, and there are sensitive nerves nearby. You also may feel lightheaded, faint, dizzy, or nauseated while your blood is drawn.

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 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. Arteries and veins are two of the body's main type of blood vessels.

They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. The vena cava is the largest vein in the body. Veins have much thinner walls than arteries. Because the pressure within them is low, veins have valves inside them to keep blood flowing only one way.

A brain hemorrhage is a type of stroke. It's caused by an artery in the brain bursting and causing localized bleeding in the surrounding tissues. This bleeding kills brain cells. The Greek root for blood is hemo.

Arteries carry blood away from the heart; the main artery is the aorta. ... Capillaries carry blood away from the body and exchange nutrients, waste, and oxygen with tissues at the cellular level. Veins are blood vessels that bring blood back to the heart and drain blood from organs and limbs.
