Answer
The human cell undergoes a process called necrosis after the nucleus condenses and blebs form. During necrosis, the cytoplasm swells due to the influx of water, eventually causing the cell membrane to rupture. This leads to the release of cellular contents into the extracellular space, which can trigger inflammation.

Answer
Apoptosis, or programmed cell death, results in the formation of apoptotic bodies. These bodies are then recognized and engulfed by phagocytes, which helps to clear dying cells without causing an inflammatory response.

Answer
In certain cases, dying cells may become larger and be taken up by neighboring healthy cells through a process similar to phagocytosis, where the absorbent cells incorporate the remnants.

Answer
Lysosomes play a crucial role in degrading cellular components. If the cell undergoes apoptosis, components within the cell are broken down by lysosomal enzymes, ensuring that cellular debris is recycled and not released into the environment.
