Final answer:
Animals use specialized organs such as lungs, kidneys, liver, skin, and large intestine to excrete waste from their bodies.
Step-by-step explanation:
Animals use specialized organs to excrete waste from their bodies. These organs include the lungs, kidneys, liver, skin, and large intestine. The lungs excrete carbon dioxide by transferring it from the blood and exhaling it. The kidneys remove waste from the blood in the form of urine, while the liver breaks down excess amino acids and toxins. The skin eliminates excess water and salts through sweat, and the large intestine eliminates solid waste.
