infarct
Ischemia. It occurs when the blood supply to a tissue is restricted or blocked, leading to a decrease in oxygen and nutrient delivery, which can result in tissue damage or cell death.
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.
Oxygen can be starved to cells due to poor blood circulation, which can be caused by conditions like heart disease, blocked blood vessels, or low blood pressure. This lack of oxygen can lead to tissue damage and cell death if not addressed promptly.
The pulmonary arteries. They are called arteries because they leave the heart but they are UNLIKE the other arteries because they have a lack of oxygen.
blood vessels, lymphatic vessels, and connective tissue
epithelial tissue
Epithelial tissue lacks blood vessels. Instead, it receives nutrients and oxygen through diffusion from nearby blood vessels in the underlying connective tissue.
It is called "angina" or more specifically "angina pectoris" (Latin a strangling of the chest). It is caused by the lack of oxygen to the heart muscles, the blood flow in the cardiac arteries being blocked, typically by atherosclerosis.
This condition is known as a stroke, specifically an ischemic stroke, which occurs when blood flow to a part of the brain is obstructed, often by a blood clot. The lack of oxygen and nutrients leads to the death of brain tissue, resulting in neurological deficits that can affect movement, speech, and cognitive functions. Prompt medical intervention is crucial to minimize damage and improve recovery outcomes.
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.
When blood flow is restricted or blocked to an organ, it can lead to tissue damage or organ failure due to lack of oxygen and nutrients. This can result in cell death and potentially life-threatening complications if not addressed promptly. Treatment often involves restoring blood flow through medications, procedures, or surgery.
