Veins

aorta carries oxygenated blood away from the heart to the whole body while vena cava carries de-oxygenated blood from the body to the heart

The renal artery takes blood to the kidney. The renal vein takes blood away from the kidney. In the kidney, the waste product urea is filtered out of the blood. So the main difference is in the amount of urea in the blood: high in the renal artery and low in the renal vein.

The Brachial Vein is a deep vein in the arm.

as long as ur blood pressure isn't too high, i would say it is a pump from working out, you added some muscle lost some fat. And BAM a vein , good job go for more!!! more than likely you didnt directly work ur arms but indirectly like chest or back. check bp at walmart bp chair.

Varicose veins are called dialated veins

No. The superior vena cava returns blood from the superior regions of the body to the right atrium. the coronary arteries supply the heart with oxygenated blood.

The hepatic portal vein in frogs is unusual in that it is divided into two portals, the hepatic and the renal. In higher vertebrates, the hepatic portal system is the only one present.

You should apply cold compresses to varicose veins. Heat dilates blood vessels, so the veins may appear more visible after a hot shower. The cold compress will cause the veins to temporarily contract, making them less visible.

In other plants, netted venation occurs, in which the large veins branch repeatedly as they enter the blade. These produce smaller, interconnecting branches as well.

FIRST you grab your genitalia FOR GREAT JUSTICE

THEN you stab yourself repeatedly in the throat with a blunt plastic straw

THEN insert drugs

veins bring blood to all parts of your body to keep you alive,because if you have no veins you wouldn't be able to move,breath or do anything.

No, only in the systemic (body) circuit. The pulmonary veins carry oxygenated blood.
All veins carry blood to the heart. The pulmonary vein carries oxygen rich blood to the heart from the lungs.

The vein carries the blood back to the heart

Arteries carry blood with oxygen to the heart.

Veins carry blood full of carbon dioxide to the lungs.

Arteries have a thick wall.

Veins have a thin wall.

Arteries have no valves.

Veins have valves.

No veins pass through the the transverse foraminae. The vertebral arteries, however, pass through these spaces on their way to the brain.

18-to 22

The thin walls of the blood vessels are capillaries around the alveolar sacs that permit diffusion of gases in every single red blood cell with oxygen inhaled

...

they are thinner to improve the pressure gradient to allow more O2 in the capillaries, because the pulmonary capillaries have the lowest blood pressure in the body (normally)

right atrium

There is no transportation system in any city that can compare in effeciency with the circular system of our body. If you can imagine two systems of pipes, one large and one small, both meeting at a central pumping station, you will have an idea of the circulatory system. The smaller pipes go from the heart to the lungs and back, while the larger ones go from the heart to the various other parts of the body. These pipes are called arteries, veins and capillaries. Arteries are vessels in which blood is carried away from the heart. In veins,the blood is coming back to the heart. In general terms, arteries are carrying pure blood to various parts of the body, and the veins are bringing back blood loaded with waste products. The pumping station is of course the heart. Arteries lie deep in tissues, except at the wrist, over the instep, at the temple and along the sides of the neck. At any of these places the pulse can be felt, which gives the doctor an idea of the condition of the arteries. The blood in arteries is bright red in color and moves through in spurts. Veins lie closer to the surface of the skin, and the blood in them is much darker in color and flows more evenly. Veins have valves and intervals all along their course.

Fact File: Blood contains red and white blood cells that float inside a liquid called plasma. It also contains thousands of different substances needed by the body. Blood carries all this things round the body and also removes waste products.

Veins and arteries don't enter bone. They are outside of bones. The only thing inside bone is bone marrow.

The pulmonary trunk is the largest artery in the pulmonary circuit that further divides into left and right pulmonary arteries before entering into the left and right lungs.

Blood from the lower extremities, blood flows through the common iliac vein. From the common iliac vein, the blood flows into the inferior vena cava on its way back to the right atrium of the heart.

The hepatic portal vein carries blood (and absorbed nutrients) from the small intestine to the liver.

Liquid flows from high pressure to low.
