Blood vessel that carries oxygenated blood from the heart to tissues and organs.
Large vessels with middle smooth muscle layer which carry oxygenated blood away from the heart to the body tissues.
A blood vessel that carries blood away from the heart, vein.
A blood vessel taking blood from the heart to the tissues of the body.
Vessel that carries blood away from the heart to the other tissues throughout the body. Except for the pulmonary artery (which carries blood to the lungs), arteries carry oxygen-rich blood. Most arteries are named for the body part they traverse or reach (e.g., the femoral artery courses dong the femur).
A blood vessel carrying blood away from the heart. All arteries except the pulmonary artery carry oxygenated blood. The walls of arteries contain smooth muscle fibers, which contract or relax under the control of the sympathetic nervous system.
One of the vessels carrying blood from the heart to the tissues. There are two divisions, pulmonary and systemic. The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs. The systemic arteries carry oxygenated blood from the left ventricle to the rest of the body.
A blood vessel that carries blood away from the heart to other parts of the body.
Major blood vessel that carries blood away from the heart.
An arterial blood vessel serves the purpose of transporting blood away from the heart. Systemic arteries specifically carry oxygenated blood that has been pumped from the lower chamber (left ventricle) of the heart to all regions of the body, excluding the lungs. Among the systemic arteries, the largest one is known as the aorta, which originates from the left ventricle. Other significant systemic arteries branch out from the aorta. On the other hand, pulmonary arteries transport blood from the right ventricle to the lungs.
Arteries can be described as tubular structures possessing sturdy, elastic, and muscular walls capable of enduring the elevated blood pressure resulting from each heartbeat. The unique composition of arteries aids in smoothing out the fluctuations in blood pressure caused by the rhythmic contractions of the heart. This ensures that by the time the blood reaches the smaller blood vessels (known as arterioles, which directly branch off from the arteries and connect to even finer capillaries), it maintains a relatively consistent pressure. In contrast, pulmonary arteries exhibit thinner walls compared to systemic arteries and carry blood at a lower pressure level.
A blood vessel that carries blood away from the heart. It is composed of an outer coat, the tunica adventitia; a middle muscular coat, the tunica media; and an inner coat, the tunica intima. An artery is thicker than a vein, largely because of the artery’s muscular middle coat, which responds to the heartbeat by converting a series of blood pulsations from the heart into a continuous flow. Contraction of the muscular coat narrows the bore of the artery, raises the blood pressure, and increases the work of the heart, while relaxation of the artery coat dilates the artery and causes a drop in blood pressure. When an artery is cut, this coat contracts, narrows the opening, and assists in limiting bleeding. Although all arteries carry blood away from the heart, they do not all carry arterial blood, that is, blood which is bright red and full of oxygen. The pulmonary artery carries the dark-colored venous blood from the right side of the heart to the lungs. There the blood is reoxygenated, collected by the pulmonary veins, and returned to the left side of the heart. The term artery is derived from the Greek term for airway. This was due to the fact that the ancients found the arteries to be empty after death and concluded that they contained air in life.
