Detailed explanation-1: -The important functions performed by the excretory system include-elimination of wastes, eliminate waste byproducts excreted by the cells, prevent the accumulation of harmful chemicals in the body, and maintain a balanced chemical concentration in the body.
Detailed explanation-2: -The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism, and, because of this, it is sometimes referred to as the excretory system.
Detailed explanation-3: -Researchers have long believed that the way the level of salt inside our bodies is controlled is fairly straightforward: when levels are too high, our brains are stimulated to make us thirsty. We drink more and excrete more urine, through which the body expels excess salt.
Detailed explanation-4: -The nephrons of the kidneys process blood and create urine through a process of filtration, reabsorption, and secretion. Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid.
