infarction
Necrosis is tissue death, and infarct means a blockage of blood flow to tissues, so it sounds like someone is describing tissue death that appears to be due to blockage of blood flow.
Dead tissue beyond a blockage is typically referred to as "necrotic tissue." Necrosis occurs when blood supply is interrupted, leading to cell death in the affected area. This can happen in various conditions, such as a heart attack or peripheral artery disease, where tissue loses oxygen and nutrients. The necrotic area may require medical intervention for removal or treatment to prevent further complications.
An embolus is a blood clot or other substance that travels through the bloodstream and blocks a blood vessel. When a vessel is blocked by an embolus, it can lead to reduced blood flow to tissues and organs supplied by that vessel, potentially causing damage or even tissue death if not promptly addressed. Treatment for a blocked vessel by an embolus may involve medications to dissolve the clot or procedures like thrombectomy to physically remove the blockage.
The muscle tissue bones that make blood are called the Cancellous bone.
A heart attack, called a myocardial infarction in medical terms, is the death of the heart's muscle tissue due to lack of blood flow. The direct cause is a blockage in one of the blood vessels that supply the heart muscle.
That is called a stroke.
The tissue in the center of bones that makes blood cells is called bone marrow. It is a soft, spongy tissue that produces red blood cells, white blood cells, and platelets through a process called hematopoiesis.
The lymph
A blood clot is called a Thrombosis a blockage of a blood vessel by a blood clot. It is most likely to happen where normal blood flow is disrupted by for example plaques of fatty atheromatous tissue in the walls of an artery or inflammation of the blood vessel. The clot eventually narrows or blocks the passage of blood causing the tissues beyond to be starved of oxygen and nutrients.
The kidneys need a good blood supply. The main artery to the kidney is called the renal artery. Reduced blood flow through the renal artery can hurt kidney function. A complete blockage of blood flow to the kidney can often result in permanent kidney failure.
An area of dead myocardial tissue is called a myocardial infarction or myocardial necrosis. This condition typically occurs due to a lack of blood flow, often resulting from a blockage in the coronary arteries. When the heart muscle is deprived of oxygen for an extended period, the affected tissue can become irreversibly damaged and die. This can lead to serious complications, including heart failure or arrhythmias.
