The soft and hard palate.
That is the palate, also known as the roof of your mouth.
There is a flap of cartilage at the root of the tongue called the epiglottis which covers over the back of the nasal cavity when you swallow to prevent food from going down into the trachea. When you start to swallow, you can feel the closing off at the back and temporary inability to breathe air in. Great safety design but not totally fail safe. Is this what you wanted to know?
nasal cavity is separated from the oral cavity by the palatine processes of maxilla and the palatine bone(hard palate).
The hard and soft palate separate the oral cavity from the nasal cavity. There are muscles and substructures with each of the associated structures, but in very simple terms, it's the palate.
Hard palate on anterior side and soft palate on posterior side, separates the nasal cavity from the oral cavity.

Some parts within the nose: Nasal cavity - this is the space behind the nose where air that we breathe passes. Nostrils - two holes of the nose where the air gets inside. Olfactory nerve - transmits the sense of smell from the nasal cavity to the nose. Hard Palate - bones separates the oral cavity from the nasal cavity. Soft Palate - closes the nasal cavity from the oral cavity when swallowing
Like the oral cavity (the mouth) you can breath in and out with this.
