What is arteries pictures?

Arteries are blood vessels that carry blood away from the heart to different parts of the body. Arteries have thick walls made up of three layers: the innermost layer is the tunica intima, the middle layer is the tunica media, and the outermost layer is the tunica adventitia. The tunica media has smooth muscle cells that contract and relax to regulate blood flow.

Arteries are typically depicted in medical illustrations and diagrams as red tubes with branching pathways. In anatomical dissection and surgical procedures, arteries are carefully identified and manipulated to avoid damaging them.

Images of arteries may also be produced using medical imaging techniques such as angiography, computed tomography (CT), and magnetic resonance imaging (MRI). These images can show the structure and function of arteries in detail, helping doctors to diagnose and treat conditions such as atherosclerosis (narrowing or blockage of arteries due to plaque buildup) and aneurysms (weakened areas in the artery wall that bulge out).
