secretions

Secretions are substances produced and released by glands in the body to perform specific functions. These include hormones, enzymes, mucus, and other fluids essential for processes like digestion, immune response, and maintaining body chemistry. For example, saliva secreted in the mouth begins digestion, while sweat released by sweat glands helps regulate body temperature. Secretions often have a protective or lubricating role, supporting overall health and bodily functions. They are typically produced in response to certain signals or needs, ensuring that the body's systems operate smoothly and effectively.
