aveoli
What are type I alveolar cells?
These alveolar cells are simple squamous and specialized for gas exchange.
This condition occurs when air enters the pleural cavity, collapsing the lung.
pneumothorax
This muscular tube extends from the internal nares to the cricoid cartilage.
the pharynx
What are type II alveolar cells?
These cuboidal alveolar cells produce surfactant to reduce surface tension.
Pneumothorax can occur due to trauma, spontaneous rupture, or this habit.
Smoking
During swallowing, the tongue pushes the food bolus into this region of the pharynx.
oropharynx
These cells in alveoli ingest bacteria, viruses, allergens, and dust
alveolar macrophages
In this disease, alveolar walls are damaged, reducing surface area for gas exchange.
emphysema
During swallowing, this flap closes over the larynx to prevent food from entering the airway
epiglottis
in emphysema, trapped old air prevents this from entering the alveoli.
fresh air or oxygen
After passing through the pharynx, the bolus enters this tube leading to the stomach.
esophagus
These muscles are overused in COPD to assist breathing.(chronic obstructive pulmonary disease)
What are accessory muscles of respiration?
The lower respiratory tract includes the lungs and this tree-like branching system
tracheobronchial tree
