To symbolize that arteries carry blood that's rich in oxygen while veins carry blood that's low on oxygen.
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.)
blood travels away from the heart through arteries and blood travels to the heart through the veins
Pulmonary Arteries lead from the heart to the lungs. Systemic arteries go everywhere else. Consequently, the pulmonary arteries are usually slightly smaller and thinner. There is also less of them.
arteries.
Renal arteries and veins service an animal's kidneys.
The capillaries are the smallest blood vessels and are usually found between arteries and veins.
the three blood vessels are the Veins capillaries Arteries the arteries.
Veins tend to be more superficial, meaning they lie closer to the surface of the skin. Arteries usually, but not always, run deeper in the tissue than veins.
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.)
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
Cellulose is what surronds veins and arteries.
Typically, it is drawn from the antecubital vein, in the arm. It can be drawn from other veins, as well, including dorsal veins in the hands and feet, and from ports inserted into larger veins, for instance.
Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
blood travels away from the heart through arteries and blood travels to the heart through the veins
The main kind of blood vessels are Veins, Arteries, and Capillaries. Arteries carry oxygenated blood to other organs. Veins carry blood with carbon dioxide back to the heart. Capillaries connect Veins and Arteries and let oxygen out to the organs and carbon dioxide in to the veins.
Arteries and veins can be different sizes, because large arteries branch into smaller arteries, which branch into capillaries. These capillaries branch into small veins, which branch into large veins. So yes, they can be (and usually are) the same size if (I am surmising this) they are the same distance from the capillaries.
The tunica media is thicker in arteries than in veins.
