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).

A group of white blood cells called lymphocytes plays a key role in the human immune response. Lymphocytes include cells called B-cells and T-cells that are responsible for flagging and fighting infections in healthy individuals.Antigens are substances that elicit the response of T-cells and B-cells in the body.When a T-cell recognizes a specific antigen, it binds to the substance and produces chemicals called cytokines. group of white blood cells called lymphocytes plays a key role in the human immune response.
