Coronary artery disease caused by atherosclerosis
Arteriostenosis is the medical term meaning abnormal narrowing of an artery. Normal, physiologic narrowing of an artery is called vasoconstriction.
Arterionecrosis is the medical term meaning tissue death of an artery or arteries. In a related term, angionecrosis is death of blood or lymph vessel tissue.
coronary atherosclerosis
coarctation
When the person is young, the tissue inside an artery is smooth, but as we age, it progressively becomes rugged and this is the beginning of the atherosclerosis.The artery becomes rigid as we age.
arteries provide oxygenated blood to the tissues they supply. ergo, a coronary artery that is blocked cannot deliver oxygen to the tissue it is supplying, and all that tissue dies... literally dies as in tissue necrosis, cellular death and just becomes a hunk of meat that flaps along with the tissue around it that still does get oxygen and can move. If a large enough piece of tissue dies or if multiple arteries get blocked then heart stops beating and death occurs.
The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.
anatomic end arteries are vessels whose terminal branches donot anastomose with branches of arteries supplying adjacent areas . Functional end arteries are vessels whose terminal branches do anastomose with those of adjacent arteries , but the caliber of anastomoses is insufficient to keep the tissue alive should one of the arteries become occluded .
Tunica Media or just Media is the central layer of arteries or veins. In the artery, it is composed of elastic tissue and smooth cell muscles.
Periarteritis
yes
Arteries, by some textbooks, are connective tissue.

artery walls have more elastic tissue and smooth muscle than veins,

Osteosarcoma is the medical term meaning connective tissue cancer of bone.
Tunica Media or just Media is the central layer of arteries or veins. In the artery, it is composed of elastic tissue and smooth cell muscles.
Arteries don't drain the pelvic organs, any other organs, or any tissue in the body. Veins drain.
Necrobiosis lipoidica diabeticorum is the medical term meaning death of tissue caused by diabetes.
