What is a mouth?

The mouth is a part of the human body, which receives food and contains saliva. The Mouth is probably one of the most important parts for your body, since it helps you get the needs you need to live your life. Without a mouth, you can't eat or drink, thus starve and die due to lack of food/dehydration.

What does a mouth look like?

Imagine it this way: 2 stacks of red bright "logs". But more human like. And that's what the mouth looks like when shut.

What are the parts of the Nose?

The visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the septal cartilage (which separates the nostrils) and the upper and lower lateral cartilages. On average the nose of a male is larger than that of a female.

The nose has an area of specialised cells which are responsible for smelling (part of the olfactory system). Another function of the nose is the conditioning of inhaled air, warming it and making it more humid. Hairs inside the nose prevent large particles from entering the lungs. Sneezing is usually caused by foreign particles irritating the nasal mucosa, but can more rarely be caused by sudden exposure to bright light (called the photic sneeze reflex) or touching the external auditory canal. Sneezing can transmit infections, because it creates aerosols in which the droplets can harbour microbes.

How can we keep our mouth healthy?

We can apply mouthwash, mouth rinse, oral rinse or mouth bath, which is a liquid and held in the mouth passively or swilled around the mouth by contraction of the perioral muscles and/or movement of the head, and may be gargled, where the head is tilted back and the liquid bubbled at the back of the mouth.We should also brush and floss teeth daily.We can apply lip balm to protect our lips from dryness also
