artérií
Arteries are blood vessels that transport blood away from the heart to tissues throughout the body. In systemic circulation, arteries usually carry oxygen-rich blood; the pulmonary arteries carry oxygen-poor blood from the heart to the lungs. Arteries begin as large elastic vessels near the heart and progressively narrow into muscular arteries and arterioles that feed capillary beds.
Arterial walls consist of three layers: the tunica intima (a smooth endothelium), the tunica media (smooth muscle
Blood flow in arteries is regulated by neural and chemical signals that adjust vessel diameter. Endothelial
Major arteries include the aorta and its branches (carotid, subclavian, mesenteric, renal, iliac, femoral), as well
Disease of arteries—such as atherosclerosis, aneurysm, dissection, or occlusive conditions—can impair blood supply and cause organ
Diagnosis of arterial conditions uses imaging methods such as Doppler ultrasound, CT angiography, MR angiography, or
