what portions of the respiratory system are referred to as anatomical dead space?

It is separated into the hard and soft palate. Its floor, the palate, forms the roof of the mouth.

The roof of the nasal cavity consists of parts of the ethmoid and sphenoid bones. This dividing wall’s anterior portion is made of cartilage bone contributed by the vomer and part of the ethmoid bones of the skull make up the posterior. The nasal cavity is divided into right and left sides by the nasal septum. Diagram of the nose By The Emirr (Diagram of Nose) CC-BY-3.0 The area immediately inside the nares, the vestibule, contains a large number of sebaceous glands, sweat glands, and hair follicles. The openings to the nose, the nares, are lined with coarse hairs to aid in filtration of particulate matter. The visible nose is actually the entryway into the nasal cavity, where the major functions of the nose occur. Variations in the size of a person’s nose, or its form, are due to differences in the various cartilages. Dense fibrous connective tissue is found under the skin of the sides lateral aspects the nose, away from the cartilage.

Two minor alar cartilages are found at the sides and base of the lateral septal cartilages. The tip of the nose contains the major alar cartilage. The medial region of the nose consists of a central septal cartilage with two lateral processes. Extending from the nasal bone is a collection of hyaline cartilages that make up the bulk of the nose. The external portion of the nose begins at the base of the frontal bone and extends over the maxilla, with the nasal bone providing the bridge of the nose.
