What is the role of mucus in the nasal cavity:
A
lighten the skull
B
increase the air turbulence in the nasal cavity
C
separate the oral from the nasal cavity
D
trap incoming bacteria and other foreign debris
Explanation: 

Detailed explanation-1: -Cells in the mucous membrane produce mucus and have tiny hairlike projections (cilia). Usually, the mucus traps incoming dirt particles, which are then moved by the cilia toward the front of the nose or down the throat to be removed from the airway. This action helps clean the air before it goes to the lungs.

Detailed explanation-2: -The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Detailed explanation-3: -It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won’t get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.

Detailed explanation-4: -The whole system of airways is lined with a thin layer of sticky mucus that traps dust particles, bacteria and other pollutants. Tiny hairs called cilia sweep mucus from your nasal cavity into the back of your throat where it can be swallowed and neutralized in your stomach.

Detailed explanation-5: -In the nose mucus helps to moisten, warm, and filter the air as it enters. (Mucous-Name of tissue; Mucus-Secretion that flows from the tissue.)
