IMMUNOLOGY

Detailed explanation-1: -It is generally the thickest layer in arteries, and it is much thicker in arteries than it is in veins. The tunica media consists of layers of smooth muscle supported by connective tissue that is primarily made up of elastic fibers, most of which are arranged in circular sheets.

Detailed explanation-2: -Muscular arteries contain more smooth muscle cells in the tunica media layer than the elastic arteries. Elastic arteries are those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries.

Detailed explanation-3: -description. The tunica media, or middle coat, is thicker in arteries, particularly in the large arteries, and consists of smooth muscle cells intermingled with elastic fibres.

Detailed explanation-4: -Thick walls of arteries help them to resist the pressure of the flow of blood in them. Elastic walls of arteries: The elastic layer allows stretching and absorbs pressure. The walls stretch and recoil in response to pumping, thus peaks in pressure are absorbed.
