artery,

blood vessel that conveys blood away from the heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

. Except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, arteries carry oxygenated blood from the heart to the tissues. The largest arterial trunk is the aortaaorta
, primary artery of the circulatory system in mammals, delivering oxygenated blood to all other arteries except those of the lungs. The human aorta, c.1 in. (2.54 cm) in diameter, originates at the left ventricle of the heart.

, microscopic blood vessel, smallest unit of the circulatory system. Capillaries form a network of tiny tubes throughout the body, connecting arterioles (smallest arteries) and venules (smallest veins).

blood vessel that returns blood to the heart. Except for the pulmonary vein, which carries oxygenated blood from the lungs to the heart, veins carry deoxygenated blood. The oxygen-depleted blood passes from the capillaries to the venules (small veins).

). Other important arteries are the subclavian and brachial arteries of the shoulder and arm, the carotid arteries that lead to the head, the coronary arteries that nourish the heart itself, and the iliac and femoral arteries of the abdomen and lower extremities. The walls of the large arteries have three layers: a tough elastic outer coat, a layer of muscular tissue, and a smooth, thin inner coat. Arterial walls expand and contract with each heartbeat, pumping blood throughout the body. The pulsating movement of blood, or pulsepulse,
alternate expansion and contraction of artery walls as heart action varies blood volume within the arteries. Artery walls are elastic. Hence they become distended by increased blood volume during systole, or contraction of the heart.

Immediate and long-term results of bronchial artery embolization for life-threatening hemoptysis.
While bronchial artery embolization remains the cornerstone of the management of severe or persistent hemoptysis, many new endoscopic procedures have demonstrated signs of efficacy in recent years.
1) Third or subsequent bronchial artery embolisation attempted for the same patient.
In 40 cases (86.95%), it was the origin for one left bronchial artery and one right bronchial artery.
[3] Hughes and Stovin hypothesized that the structural changes in the bronchial artery causes inadequate nutrition to the pulmonary artery via the vasa vasorum, which in turn lead to inflammation and damage to the elastic tissue and cause arterial aneurysm.
"Transcatheter embolisation of the bronchial artery, which was first attempted in 1973, has now become an accepted method of therapy for such cases."
Bronchial artery dilatation on MDCT scans of patients with acute pulmonary embolism: Comparison with chronic or recurrent pulmonary embolism.
Bronchial artery embolisation offers a minimally invasive procedure, is a treatment of choice in such patients.
Massive hemoptysis is a life threatening respiratory emergency with high mortality and the bronchial artery (BA) is the most frequent source [1].
For extra-cardiac malformations, 12 patients were discovered to have pulmonary artery hypertension, 11 patients to have persistent ductus arteriosus [Figure 2], 6 patients to have bronchial artery dilation, 3 patients to have an aberrant right subclavian artery, 1 patient to have an isolated left subclavian artery [Figure 3], 1 patient to have aorta-pulmonary artery collateral circulation and 3 patients were identified having ascending aorta (AA)-descending aorta (DA) collateral circulation.
