The process by which the body eliminates all metabolic wastes is known by which of the following?

Excretion is a vital process for maintaining homeostasis in the body. It involves the removal of metabolic waste products such as urea, carbon dioxide, and excess water from the body. The organs involved in excretion include the kidneys, liver, lungs, and skin.

Circulation is the process by which blood is pumped through the body to deliver oxygen and nutrients to the cells and tissues.

Breathing, also known as respiration, is the process by which oxygen is taken in and carbon dioxide is released from the body.

Digestion is the process by which food is broken down into smaller molecules that can be absorbed and used by the body. The waste products of digestion are eliminated through the digestive system, not through excretion.
