What is the difference between apoptosis and necrosis?

apoptosis and necrosis relate to two different types of cellular death in living organisms. The main difference between the two processes is how they come. Cells undergoing apoptosis, sometimes referred to as cellular suicide or programmed cellular death, go through the natural process initiated by the cell itself to safely deprive the body of the old cells. When the cells die necrosis, the catalyst of death is not the cell itself, but some external factor that changes the normal physiological condition of the body and causes cells to perish. There are several other observable differences between the two processes, including the number of cells and the impact that every cell death process has on the overall health of the organism. This occurs when the cells are dangerous or lose their function. For example, apoptosis is a natural programmed processy that occurs inside the tadpole tail cells when tadpole becomes an adult frog and no tail is needed, they are programmed to die, which is behindthe consequence of the loss of the tail. If cells are dangerous - for example, mutant cells that have the potential to turn cancer - also initiate apoptosis, making this natural process an integral part of cancer prevention.

necrosis, on the other hand, occurs as a result of cell damage caused by some external factor, such as disease or trauma. For example, necrosis to healthy cells can be caused by the bite of dangerous spiders such as Brown Recluse, or is the result of the presence of the virus. This process results in premature death of otherwise useful and healthy cells.

Another difference between apoptosis and necrosis is the number of cells involved. Apoptosis often includes death only one unhealthy or unnecessary cell. However, necrosis generally involves the death of many cells because the catalyst of the process - trauma or disease - usually damages more than one cell.

one of the largestThe way apoptosis and necrosis differ is in the impact that they have on the overall health of the organism. Dangerous cellular content that die of apoptosis is generally eliminated by other healthy cells, preventing harmful content to influence the rest of the organism. The body has no way to remove cellular content when the cell dies with necrosis. This means that other tissues of the body can be affected by cellular content that generally initiates an inflammatory response that triggers the immune system.
