What are the 3 main parts of the excretory system?

Answer 1

Here are the three main parts of the excretory system and what they do:

The skin - it's 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 - it's part of the digestion system, but also plays a role in the excretory system. The liver has a small organelle called a peroxisome, which is responsible for taking high levels of toxicity and converting them to less toxic substances. Bile is a waste product in this process and is used in the digestive process.The kidneys - it's to remove nitrogenous wastes from the body. Nitrogenous means that it is rich in the element nitrogen. Nitrogen in high concentrations in the body can cause several problems such as joint pain, strokes or heart attacks. The kidney is made up three parts: the renal cortex, the renal medulla and the renal pelvis. All mammals have two kidneys. The kidney's primary function is to regulate various body fluids and salt concentration.
