What are the two entrances for oxygen to enter the respiratory system? Nose and mouth.
Where does the air go to from the nose and mouth? Pharynx.
In between the pharynx and the trachea what structure does this lesson leave out? The larynx.
Where is the trachea located in reference to the esophagus? Anterior.
What structures moisten the air in the Respiratory System? Nose and mouth.
What is the name for the small air sacs at the end of the bronchioles? The alveoli.
Where does gas exchange take place in the lungs? In the alveoli.
What is the main muscle of respiration? Diaphragm.
What happens when we inhale? The diaphragm contracts, lowering the air pressure in the lungs, allowing them to take in air. Exhale? The diaphragm relaxes, increasing the air pressure so the lungs release air.
