EVERYDAY SCIENCE

Detailed explanation-1: -Some of the specific waste products that must be excreted from the body include carbon dioxide from cellular respiration, ammonia and urea from protein catabolism, and uric acid from nucleic acid catabolism.

Detailed explanation-2: -excretion, the process by which animals rid themselves of waste products and of the nitrogenous by-products of metabolism. Through excretion organisms control osmotic pressure-the balance between inorganic ions and water-and maintain acid-base balance.

Detailed explanation-3: -Although the kidneys are the main organs of excretion, several other organs also excrete waste s. They include the large intestine, liver, skin, and lungs.

Detailed explanation-4: -Liver converts it to urea, which is excreted in urine. Waste products released in the process of other types of catabolism are removed from our body through the skin, kidneys, lungs and intestines. Metabolic waste is produced when a cell uses oxygen and nutrients (usually glucose and fats) to create energy.
