cilia
The cilia on their surface trap dust and microbes, then pass the trapped substances along with mucus to the throat, where they can then be swallowed. This then protects the lungs.
I think you are referring to your tonsils, as you do not have lungs in your throat.
Someone who has drowned would not have air trapped in their lungs.
from nose through airway in throat into lungs
The inner walls of the lungs are covered with cilia, small microscopic hairs that are consistently moving in a wave-like flow upwards toward the throat and mouth.
Same way you eat and drink. Gravity is not required, muscles in your throat and suction from your lungs keep food moving toward the stomach
The respiratory system is what system your lungs are apart of, and your throat, if it's the same as the esophagus, is apart of the digestive system.
systemic
My stomach
the trachea
Cilia is a hair like cell in your body, mainly in your lungs protecting you from debris from the air. These little hair like cells protect your lungs by carrying debris from your lungs and back up to be swallowed and destroyed by the powerful stomach acids in your body. The mucus lining in the respirator tract helps collect debris, bacteria and mucous away from the lungs.
Most likely. You will burn your throat and lungs.
