Hence: Any continuous or ramified channel of communication; as, arteries of trade or commerce
They have tricker and more muscular walls than veins, and are connected with them by capillaries
Red blood arteries are the blood vessels that carry the red or oxygen-rich blood away from the heart and towards the organs of the body The arteries are thicker and stronger then veins The blood pressure in the arteries is nearly 8 times higher than the blood pressure in the veins Arteries are vulnerable to atherosclerosis and plaquing, while veins to not develop these degenerative lesions The principle artery of the body (called the aorta) arises from the heart and delivers blood through its many branches to every tissue of the body
a major thoroughfare that bears important traffic a blood vessel that carries blood from the heart to the body
muscular- and elastic-walled blood vessel that carries oxygenated blood from the heart to the body
—A large blood vessel that carries blood from the heart to tissues and organs in the body
You can refer to an important main route within a complex road, railway, or river system as an artery. Clarence Street was one of the north-bound arteries of the central business district. Vessel that carries blood from the heart to other parts of the body (see cardiovascular system). Arterial blood carries oxygen and nourishment to tissues; the one exception is the pulmonary artery, which conveys oxygen-depleted blood from the heart to the lungs for oxygenation and removal of excess carbon dioxide. Arteries are muscular, elastic tubes that transport blood under the pressure of the heart's pumping action, which can be felt as the pulse. Large arteries branch off from the aorta and give rise to smaller arteries, down to the threadlike arterioles, which branch into capillaries. An artery wall's inner layer (tunica intima) consists of an endothelial (cellular) lining, a fine connective tissue network, and a layer of elastic fibres. The middle layer (tunica media) is mostly smooth muscle cells. The outer layer (tunica externa) contains supportive collagen fibres. See also capillary; vein
blood vessel that carries blood from the heart to the organs and tissues throughout the body; walls consist of smooth muscle
