What type of blood does the coronary artery deliver to the heart?
The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.
How does the blockage of a coronary artery lead to a heart attack?
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.
What is the tissue that lines the outer layer of the inner surface of an artery?
Connective Tissue
What is an artery classified as tissue or organ?

Is Arterionecrosis the tissue death of an artery or arteries?
yes
What is the medical term meaning tissue death of an artery or arteries?
Coronary artery disease caused by atherosclerosis
What is Inferior Infarct?
An inferior infarction refers to a heart attack (myocardial infarction - MI) involving the inferior and possibly the posterior wall of the heart. This area of the heart is supplied blood by the right coronary artery and sometimes a part of it is supplied by a small branch of the left coronary artery. If the right coronary artery becomes diseases with lipid laden plaques, and a plaque ruptures, it can cause an infarction in the inferior or posterior walls of the heart. This will frequently cause chest pain, nausea, vomiting, sweating, shortness of breath, and possibly syncope. Sometimes, the only symptoms are nausea and vomiting, especially in women, the elderly, and those with Diabetes mellitus. When your physician performs an EKG, there can be changes seen in the inferior leads (II, III, aVF, and possibly V1 or V2). This is how s/he diagnoses an acute MI. You may need clotbusting medication, but if it is available, a cardiac catheterization can sometimes open the artery and prevent further damage to the cardiac muscle.
What are the three layers of an artery and state their function?
The three layers of an artery are Endothelium, smooth muscle, and connective tissue.
What is the medical term meaning Inflammation of tissue surrounding an artery?
Periarteritis
What kind of epithelium tissue lines the artery?
Simple squamus or endothelium
What primary blood supply to the diaphysis of a long bone is through the?
The primary blood supply to the diaphysis of a long bone is through the nutrient artery, which enters the bone through the nutrient foramen. This artery provides blood to the medullary cavity and inner portions of the bone.
What tissue has good blood supply and an extensive extracellular matrix?
connective tissue
