Detailed explanation-1: -Kidneys. The paired kidneys are often considered the main organs of excretion. The primary function of the kidneys is the elimination of excess water and wastes from the bloodstream by the production of the liquid waste known as urine .
Detailed explanation-2: -The urinary tract is one of the systems that our bodies use to get rid of waste products. The kidneys are the part of the urinary tract that makes urine (pee). Urine has salts, toxins, and water that need to be filtered out of the blood.
Detailed explanation-3: -The skin is another excretory organ that rids the body of wastes through the sweat glands. The liver and intestines excrete bile pigments that result from the destruction of hemoglobin.
Detailed explanation-4: -The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney. The filtrated blood is carried away from the kidneys by the renal vein (or kidney vein).
Detailed explanation-5: -The skin has sweat glands that secrete a fluid waste called perspiration, or sweat, which is a pathway for water and ion removal from the body, among other things. The lungs diffuse gaseous wastes, such as carbon dioxide, from the bloodstream as a normal part of respiration.
