The term 'eliminate from the body' can be defined as the process of removing substances from the body. This can be done in a variety of ways, including excretion, egestion, and emission. Excretion is the process of eliminating waste products from the body, such as urine and sweat. Egestion is the process of eliminating undigested food from the body, usually through the digestive system. Emission is the process of releasing substances from the body, such as carbon dioxide and other gases. All three of these processes are important for maintaining a healthy body.
