Blood Vessel
The blood vessels are the part of the circulatory system that transports blood throughout the body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.

Famous quotes containing the words blood and/or vessel:
“It is a strange, strange fate, and now, as I stand face to face with death I feel just as if they were going to kill a boy. For I feel like a boy—and my hands so free from blood and my heart always so compassionate and pitiful that I cannot comprehend how anyone wants to hang me.”
—Roger Casement (1864–1916)
“It is plain that there is no separate essence called courage, no cup or cell in the brain, no vessel in the heart containing drops or atoms that make or give this virtue; but it is the right or healthy state of every man, when he is free to do that which is constitutional to him to do.”
—Ralph Waldo Emerson (1803–1882)
