The respiratory system has two parts, upper and lower, which are responsible for ventilation (air passage from inside to outside and vice versa). The upper airways include the nostrils, sinuses, tonsils and adenoids, larynx and trachea, and the lower respiratory tract includes the lungs (bronchial branches and alveoli). On each side of the nose, there are three separate airways called tentacles. These tentacles heat and humidity and filter the incoming air. Mucus secretions are constantly flowing in the nasal cavities and cause its moisture. These secretions are secreted from the cells of the nasal goblet and are constantly flowing to the throat by ciliated bodies. The olfactory neurotransmitters are located in the nasal membrane. The sinuses around the nose are four pairs of bony cavities made up of epithelial tissue and mucus-secreting glands that drain their mucus secretions into the nasal cavity.
