SENSE ORGAN - NOSE (STRUCTURE AND FUCTION) Here we will discuss about structure and function of sense organ (nose) NOSE Human nose is the first part of the respiratory organ of passing air. It is the organ of sense in the body, sense of smell is called as - olfaction . It is also called as organ of olfaction.
