MAJOR COMPONENTS:

 

While integumentary system is made up of skin, but our sensory system is made up of 5 important senses and skin is one among them. The five sensory organs are:
- EYES: Eyes are the organ of sight i.e. vision sense. They are composed of a pair of fluid-filled spherical structures that occupy the orbits of the skull. Incoming light is refracted by the cornea of the eye and transmitted through the pupil to the lens, which focuses the image onto the retina.
- EARS: Ears are the organ of hearing, responsible for maintaining equilibrium as well as sensing sound. Thus ears serve as hearing sensor. Their structure is divided into three parts as- external ear, the middle ear, and the inner ear.  
- MOUTH: Mouth is the body opening through which our voice comes out and food is taken in. It serves as taste sensor.
- NOSE: Nose is the part of the human face that contains the nostrils and organs of smell and forms the beginning of the respiratory tract. Nose also helps in controlling voice. It serves as the smell sensor.
- SKIN: Our skin serves three main purposes; namely, protection of the inner organism, regulation of body temperature and elimination of cell waste and systemic refuse.
