Overall, the excretory system acts in order to maintain a healthy fluid environment within animals. It works in order to remove nitrogenous wastes such as ammonia (which is a highly toxic compound). Due to the fact that osmoregulation is structurally and functionally linked in many animals, the process of osmoregulation will also be included. Osmoregulation is the general process by which animals control solute concentrations and balance water ga

The excretory system plays a vital role in ridding the body of extraneous wastes and toxins. The excretory system is made up of various internal organs that work together to detoxify the body. The Skin The skin is responsible for producing sweat, which helps regulate the salt concentration in the body. When you sweat, the salt helps evaporate the water and, in turn, cools off the body. The Liver The liver is part of the digestion system,

The excretory system is in charge of getting rid of bodily wastes and excess water. Jobs of the excretory system: Maintain volume of extracellular (outside the cells) fluid Maintain ionic balance in extracellular fluid Maintain pH and osmotic concentration of the extracellular fluid.

The excretory system is responsible for removing unwanted waste products from the body's chemistry. Generally speaking, excretion is the process of separating wastes from the body's fluids and eliminating them. Examples include the removal of carbon dioxide in the air we exhale, and unwanted nitrogen in sweat, nails and hair. (Don't confuse excretion with defecation. Defecation is getting rid of undigested foods from the body... via the colon.)
