The five main senses that humans possess are sight, hearing, taste, smell and touch. The five senses are a part of the body's sensory system, which is part of the nervous system. Each main sense is connected to a specific organ in the body: eyes for sight, ears for hearing, tongue for tasting, nose for smelling and skin for touching.
All of the senses in the sensory system work together constantly to collect and process information from the body and the external environment, according to Education Portal. The nervous system sends that information to the brain, which responds appropriately. The sense of sight works by using the eyes to collect images of light, color and distance, which the nervous system sends to the brain to decipher what the eyes are seeing. Receptors on the skin sense the vibrations of anything the body comes in contact with, which the brain interprets into a physical feeling.
To hear, the eardrums inside the ears pick up sound waves and vibration, which are sent to the brain to decipher the sound. Taste is a chemical sense that uses receptors on the tongue to send sweet, salty, sour or bitter signals to the brain. Smell is also a chemical sense. The receptors in the nose send odors to the brain to interpret the smell. According to Brain Facts, taste and smell are closely intertwined when it comes to interpreting taste, as the brain uses the chemical receptors on the tongue and in the nose together to detect food flavors.
