The part of the nose that separates the two nostrils is called the nasal septum. The nasal septum is made up of cartilage and bone, and its primary function is to divide the nasal cavity into two separate chambers. This structure helps to control the airflow in and out of the nostrils, allowing for proper breathing and air circulation. A deviated septum occurs when the nasal septum is not straight and centered, leading to one nostril being larger than the other. This can cause difficulty breathing, snoring, and sinus issues. In severe cases, surgery may be required to correct a deviated septum and improve breathing. Maintaining a healthy nasal septum is important for overall respiratory health. Keeping the nasal passages clear of debris and irritants can help prevent issues with the nasal septum. Using a saline nasal spray or a neti pot can help keep the nasal passages moist and clear of congestion. If you are experiencing chronic nasal congestion, difficulty breathing, or frequent sinus infections, it is important to consult with a healthcare provider. They can evaluate the condition of your nasal septum and recommend appropriate treatment options. For more information on the nasal septum and its role in respiratory health, check out the following resources: - [Mayo Clinic - Deviated Septum](https://www.mayoclinic.org/diseases-conditions/deviated-septum/symptoms-causes/syc-20351709) - [WebMD - Nasal Septum Anatomy](https://www.webmd.com/allergies/picture-of-the-nasal-septum) - [American Academy of Otolaryngology - Nasal Anatomy](https://www.entnet.org/content/nasal-anatomy) Understanding the function and structure of the nasal septum can help individuals take better care of their respiratory health. By keeping the nasal passages clear and seeking medical attention when needed, individuals can maintain optimal breathing and overall well-being.
