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 main organs in the immune system are the bone marrow, thymus, spleen and lymph nodes. Let us have a look at these immune system organs and functions.Bone Marrow: All the cells of the human immune system are formed in the bone marrow, found within the bones, by a process called hematopoiesis. cells that evoke a detrimental autoimmune response get eliminated. Spleen: This organ of the immune system is composed of T-cells, B-cells, natural killer cells, macrophages, dendritic cells and red blood cells.
