Final answer:
Volatile anesthetic agents are primarily eliminated from the body through exhalation, as they are administered via inhalation and vaporized in the bloodstream before being breathed out through the lungs.
Step-by-step explanation:
Volatile anesthetic agents are eliminated from the body predominantly via exhalation. These agents are often administered as volatile liquids or gases using an anesthesia machine, which vaporizes the liquid anesthetics. Once administered, the volatile anesthetic moves through the bloodstream and is eventually evaporated from the lungs, as the body exhales. Additional routes of elimination like the kidneys and sweat are less significant for volatile anesthetics compared to the lungs. The excretory system is responsible for removing wastes and excess water from the body in various forms, including gases, liquids, and solids, with each component of the system specialized in different forms of waste.
