The document discusses the five human senses - touch, smell, taste, hearing, and sight. It describes the sensory organs associated with each sense and their basic functions. For touch, the skin contains receptors that detect sensations like pressure, heat, and cold. The nose contains smell receptors that detect chemicals in the air. Taste buds on the tongue allow for the sensing of the four basic tastes. Hearing occurs through the outer, middle, and inner ear which detect sound. Finally, sight takes place through the eyes, which are sensitive to light and contain the retina for vision.
