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 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.
The vascular tissue in plants made of dead cells that transport water and minerals from roots is called xylem. Xylem tissue is responsible for conducting water and nutrients upward from the roots to the rest of the plant.
Damaged tissue following a severe burn is called necrotic tissue. This tissue is dead and cannot be saved, requiring removal to prevent infection and promote healing.
The replacement of dying and dead tissue is called tissue regeneration or repair. This process involves the formation of new tissue to restore the structure and function of the affected area. In some cases, this can occur through natural healing mechanisms, while in others, medical interventions may be necessary to promote regeneration.

Dead myocardial tissue does not regenerate or get replaced by new healthy tissue. Instead, the body forms scar tissue in place of the dead tissue. This can lead to decreased cardiac function and potential complications.
Dead black skin tissue is typically referred to as necrotic tissue. This can result from various causes such as infection, poor blood circulation, or trauma. It is important to seek medical attention for proper evaluation and treatment.
A large area of necrosis that has progressed to decay is called gangrene.
The area is known as a foci of necrotic tissue, eventually turning into fibrosed (scar) tissue. The process by which this occurs is tissue ischaemia (where not enough oxygen is supplied to the heart tissue to meet its requirements).
