Answer:
There are air filters to purify the air and water filters to clean the water. Well, the kidneys are like a filtering system, too. They contain nephrons, which filter waste from the blood in two stages. First, nephrons take waste as well as needed materials out of blood. Then, the materials the body needs (like water and glucose) are returned to the blood and wastes are eliminated from the body. This is one way the kidneys maintain homeostasis. The kidneys also regulate the amount of water in the body. The amount of water the kidneys return to the blood depends on the conditions inside and outside of the body. This is another way the excretory system maintains homeostasis. For example, you will make more urine on a cool day when you have drunk a lot of water than you will on a hot day when you've hardly had anything to drink.

“ The nose- Warms and moisten air. The nasal cavities are involved in the resonance of tones.
The oral cavity- Includes the lips, teeth, and tongue. The structures serve as articulators.

The larynx- An organ consisting of a cartilaginous framework containing muscles and joints. The vibratile part of the larynx are the vocal folds which are the producers of sound.
The Lungs- They supply a stream of air which passes through the trachea.
The vocal folds- They vibrate throwing the stream of air into a series of complex vibrations. (Punt, 1979 and Henderson, 1979).”
