How the septum is made?

The septum, a partition that divides the nasal cavity or the heart, is formed through a series of developmental processes. In the heart, it develops from the fusion of tissue structures during embryogenesis, specifically from the endocardial cushions and muscular ridges. In the nasal cavity, the septum is created by the fusion of the nasal processes and the growth of the cartilaginous and bony structures. These processes ensure proper separation and function of the respective systems.
