What is an area of tissue that becomes necrotic due to a lack of O2 called?
An area of tissue that becomes necrotic due to a lack of oxygen is called an infarct. This typically occurs when the blood supply to a specific area is blocked, leading to tissue death.
In the context of the blood vessels that supply blood to the kidneys what are the arteries that originate from the arcuate arteries and supply blood to the renal cortex called Hint?
The arteries that originate from the arcuate arteries and supply blood to the renal cortex are called interlobular arteries. These arteries branch off from the arcuate arteries, which run along the boundary between the renal cortex and medulla, and then extend into the cortex, providing oxygenated blood to the nephron structures within.
Cardiac muscle tissue is supplied with nutrients and oxygen by which part of the human transport system?
Cardiac muscle tissue is supplied with nutrients and oxygen by the coronary arteries, which branch off the aorta and supply blood to the heart muscle. These arteries ensure adequate delivery of oxygen and nutrients to the heart for proper function.
Agents that dissolve already formed clots are called?
Thrombolytic agents. These medications work by breaking down blood clots to restore blood flow to blocked arteries or veins. They are often used in emergency situations such as heart attacks or strokes.
Is vascular tissue composed of red blood cell and white blood cells?
No, vascular tissue is not composed of red blood cells and white blood cells. Vascular tissue is made up of vessels that transport blood throughout the body, while red and white blood cells are components of blood itself. The vascular tissue includes arteries, veins, and capillaries.
What is lack of blood to a tissue fed by blocked arteries?
infarct
What can happen when blood supply to the heart is blocked-?
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
Which blood vessels supply oxygenated systemic blood to the lung tissue?
Pulmonary arteries
What arteries nourish the heart?
The coronary arteries are the blood vessels that nourish the heart. Even though blood goes through the heart, that blood is not the way that the muscle itself picks up nutrients and disposes of wastes.
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.
Which vessels carry blood from the heart to the tissue?
Arteries. AORTA carry blood from the heart {left ventricle} to the tissue.
What is the operation to get past blocked arteries of the heart and deliver blood?
coronary bypass
What is the role of the Coronary Arteries?
Supply blood to the heart tissue.
What is blood pumped through to get to the lungs and body tissue?
Arteries.
How good are statins?
When there are high levels of cholesterol in the blood stream, it can collect within the blood vessels causing them to become narrowed or blocked. This is bad enough when in a peripheral artery, but can be lethal if it occurs in the coronary arteries. These are the vessels that provide the blood supply to heart muscle. If they become narrowed, blood struggles to get to the tissue meaning the oxygen level in the tissue becomes depleted and it is at risk of dying. If the coronary arteries become completely blocked the chance of suffering from a heart attack is very high. By helping the blood cholesterol to drop the arteries are not only more protected from becoming more blocked, but may in fact force the cells to take their cholesterol from existing supplies and reduce any existing blockages; this can help reduce the damage that has already occurred.
The smooth muscle tissue layer of the arteries and veins?
the middle layer, called the tunica media
What is the effect of smoking on the blood vessels?
The blood vessel gets blocked. In the heart, if one of the coronary arteries get blocked by smoking, it can cause a myocardial infarction (Heart Attack).
