nasopharynx

After this, it passes through the _____, the middle region of the throat that sits behind the tongue.

oropharynx

______ moves into the erythrocytes while____ moves into the alveolar sacs

oxygen, carbon dioxide

The trachea branches into the right and left ____ , which then branch into the ______ which carry air to each lobe of the lung.

primary bronchi/ bronchioles

The branching continues in the bronchial tree until the ai reaches the smallest diameter tubes known as _____.

three/two

Air continues to flow into a short, wide diameter tube with hyaline cartilage rings known as the _____.

trachea

The last stop for airflow is the _____, which contain 1 pneumocytes capable of performing gas exchange at the respiratory membrane.

alveolars sacs

At the distal end of the tube is a structure called the ____ which contains mechanoreceptors capable of initiating a powerful cough reflex if activated by food or liquid

carina

these tubes do not have,

cartilage, instead they have smooth muscle in the walls to allow bronchodilation and bronchoconstriction
