Blood is supplied to the myocardium by means of the?
coronary
What is subendocardium?
There don't seem to be a lot of good definitions of "subendocardium" but most references describe the subendocardial layer as that supplied by the coronary arteries deep in the myocardium. Literally, it means below the endocardium so presumably is the portion of the myocardium closest to the endocadium, which is incidentally the region most likely to be affected by myocardial infarction due to the decreased cardiac blood supply in this area.
What is the definition of myocardium?
"Myo-" means muscle and "-cardium" means heart. So myocardium is heart muscle. It's the stuff that actually does the work of contracting the heart to pump blood around.
What is blood carried in?
Haemoglobin, oxygen, and iron are carried by blood cells.
Deficient blood supply to the myocardium is?
Deficient blood supply to the myocardium is: ischemia Ischemia is the medical terms for deficient blood supply to the myocardium. The suffix -emia denotes a blood condition; ischem/o means to hold back. With occlusion from atherosclerosis, the blood flow is restricted, resulting in deficient blood supply.
What contains deoxygenated blood?
Veins carry deoxygenated blood from the tissues and organs to the heart. Arteries are the means for carrying the oxygenated blood.
What role do arteries and veins play in the excretory system?
Veins and arteries are in the circulatory system. Therefore that means they have something to do with pumping blood to cells around the body. So I would say that the role the arteries play in the body is that it carries blood to and from the heart to other parts of the body
What organs or muscles do renal arteries bring blood?
"Renal" means "of or pertaining to the kidneys."
What does arteries mean?
The arteries are the blood vessels that generally carry oxygenated blood from the heart around the body. 'Arteries' comes from the Greek 'arteria', which means windpipe. People in ancient times believed the arteries were empty, containing only air. If someone had been killed due to blood loss, the arterial pressure would have causes the arteries to drain, which is why they may have looked empty on examination.
What causes claudication?
You get claudication in the Buerger's disease. That means there is pain in the calf muscles. This happens due to less blood supply to the muscles. As you walk, more blood is required to meet the increased oxygen demand. This can not be supplied by the narrowed blood vessels.The muscles get ischemia. Here the medium sized arteries are involved. Almost always the patient is chronic smoker.
What structure does blood returning from the heart muscle drain?
The arteries. Unfortunately this is a badly worded question, but it essentially means from the heart, where does the blood go/drain to?
Why the blood vessel that carrying oxygenated blood from lungs is a vein while the the other vessels carrying oxygenated blood are arteries?
It differs in pulmonary arteries and veins because they do the opposite thing to normal arteries and veins. Arteries usually carry oxygenated blood away from the heart to the body but pulmonary means lungs and the pulmonary artery carries de-oxygenated blood away from the heart but to the lungs and not round the body. Veins usually carry de-oxygenated blood back to the heart but the pulmonary vein carries oxygenated blood to the heart which then pumps it into the aorta which takes it to the body. bla bla bla
