3. The nasal septum, which separates the left and right chambers of the nose.
4. The urinary bladder septum, which separates the compartments within the bladder.

Function:

Medical Significance:

Septum-related medical conditions, such as a deviated nasal septum or ventricular septal defect, can cause significant health issues and may require medical intervention.
