Humans primarily use the nose for breathing due to its roles in olfaction, humidifying air, and filtering particles. The nasal membranes process odors and relay them to the brain, enhancing the sense of smell. While the nose is not essential for breathing, it significantly contributes to respiratory efficiency. Certain amphibians, such as frogs, can absorb oxygen through their skin, demonstrating alternative respiration methods in the animal kingdom.
