The human body is composed of five senses : sight , smell , taste , hearing and touch .
They are part of the sensory system , responsible for sending the information obtained to the central nervous system, which in turn analyzes and processes the information received.
These capacities are related to organs or parts of the human body (eyes, nose, mouth, ears, hands) and correspond to the perceptions of men in the world.
They are carried out through the process of translation, analysis and processing of sensory information, which often determined the survival of humans, as well as animals on planet Earth.
The five senses
The eyes are the organs responsible for the sense of sight , since they visualize the object and send the message to the brain that does the decoding, interpreting it.
The nose is the organ responsible for the sense of smell , that is, the property of feeling the smell or odor of things.
In this way, the nose captures odors and sends the message to the brain, which processes the information.
The tongue is the organ responsible for the sense of taste , as it captures and distinguishes the taste of food (salty, sweet, sour, bitter), in addition to the sensations of hot and cold.
Thus, the taste buds decode the taste and send the information to the brain.
The ears are the organs responsible for hearing , insofar as they detect sounds, noises and noises from outside, and send these messages to the brain, which interprets them.
The touch is characterized by the sensation of touch and therefore is related to the contact with the skin, through the sensory neurons responsible for sending messages to the brain.
Although it is often related to the hands , this human sense involves any type of sensation experienced by the skin, be it the feet, belly, legs, among others.
