It draws water from its surroundings, making it swell, which softens stool and adds bulk to it, which in turn helps it pass. Like coffee, some kinds of fiber (like beans) can contribute to constipation, so always drink plenty of water.
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).

The immune system is composed of a number of cells, tissues and organs that work in association and attacks the disease causing microorganisms and protect the human body. The cells of the immune system are the leukocytes or the white blood cells. They are of two main types that work in combination and destroy organisms and substances that invade the body. Leukocytes are manufactured and stored in multiple organs of the body such as the spleen, bone marrow and the thymus gland.
