Introduction:
Nasopharynx is the upper region of the pharynx that connects with the posterior portion of nasal cavity present above the soft palate. The soft palate is present in between the oral cavity and nasopharynx. The human respiratory system is segregated into parts namely upper and lower respiratory system. The organs present in both the systems are different and perform a specific function that is important for the respiration of the organism.
