GROSS ANATOMY

Detailed explanation-1: -Nostrils (nares): These are the openings to the nasal cavities that are on the face. Septum: The septum is made of bone and firm cartilage. It runs down the center of your nose and separates the two nasal cavities.

Detailed explanation-2: -The nasal septum is the cartilage and bone in your nose. The septum divides the nasal cavity (inside your nose) into a right and left side. When the septum is off-center or leans to one side of the nasal cavity, it has “deviated.” Healthcare providers call this a deviated nasal septum.

Detailed explanation-3: -Air enters the nasal cavity from the outside through two openings: the nostrils or external nares. The openings from the nasal cavity into the pharynx are the internal nares. Nose hairs at the entrance to the nose trap large inhaled particles.

Detailed explanation-4: -A perforated septum is usually caused by the loss of blood flow to both sides of the septum. This causes the cartilage to deteriorate, which prevents proper airflow and worsens as air slips through from one nostril to the other through the hole.

Detailed explanation-5: -A deviated septum occurs when the thin wall (nasal septum) between your nasal passages is displaced to one side. In many people, the nasal septum is off-center-or deviated-making one nasal passage smaller.
