As a biological scientist with a focus on cellular biology, I have a deep understanding of the processes that occur within our bodies, including the fate of cells that reach the end of their natural lifespan or are damaged beyond repair. When cells in our body die, they undergo a process known as cell death, which can occur through various mechanisms, with the most common being apoptosis and necrosis.
Apoptosis, often referred to as programmed cell death, is a highly regulated and controlled process that plays a crucial role in maintaining the health of an organism. It is a natural part of the body's life cycle, allowing for the removal of cells that are no longer needed or are potentially harmful. During apoptosis, the cell's genetic material is packaged into small fragments, and the cell membrane forms 'blebs' or protrusions that are eventually engulfed by neighboring cells or specialized immune cells called phagocytes. This process is efficient and does not cause inflammation or damage to the surrounding tissue.
On the other hand, necrosis is a form of cell death that occurs as a result of severe cellular injury, often due to factors such as ischemia, toxins, or trauma. Unlike apoptosis, necrosis is an uncontrolled process that leads to the rupture of the cell membrane and the release of the cell's contents into the extracellular space. This release can trigger an inflammatory response as the immune system recognizes the damaged cells and their contents as harmful. The immune system then works to clear the debris and prevent the spread of potential infections.
In both cases, the body has mechanisms in place to deal with the aftermath of cell death. Phagocytic cells, such as macrophages, play a critical role in the clearance of dead cells and the resolution of inflammation. They engulf and digest the cellular debris, effectively recycling the components and preventing the accumulation of harmful substances.
However, if the immune system is compromised or overwhelmed, the process of clearing dead cells can become less efficient. This can lead to the accumulation of cellular debris, which may trigger further inflammation and contribute to the development of various diseases, including autoimmune disorders and chronic inflammatory conditions.
In summary, the fate of cells that die in our body is determined by the type of cell death they undergo. The body has evolved sophisticated mechanisms to handle the clearance of dead cells, ensuring that the process is as non-disruptive as possible. When these mechanisms are functioning properly, they help maintain the overall health and integrity of the organism.

Typically, human cells die by apoptosis (programmed cell death) or necrosis (due to ischaemia, loss of blood flow). ... Without fuel and immune circulation, the cell deteriorates and is susceptible to infection. Toxic materials seep out, uncontrolled, into the surrounding cells and tissues, causing even more damage.
