It draws water from its surroundings, making it swell, which softens stool and adds bulk to it, which in turn helps it pass.

The immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs). Cells may be unhealthy because of infection or because of cellular damage caused by non-infectious agents like sunburn or cancer.he immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs).
