What is the primary function of the epiglottis?
Answer: To prevent food and liquids from entering the larynx during swallowing
The epiglottis folds over the glottis during swallowing to prevent food and liquids from entering the larynx and trachea.
The trachea bifurcates into the right and left primary bronchi at which anatomical landmark?
Answer: Carina
The carina is the internal ridge at the point of tracheal bifurcation into the right and left primary bronchi, located at the level of the sternal angle.
How many lobes does the right lung have?
Answer: Three
The right lung has three lobes (upper, middle, and lower) separated by the horizontal and oblique fissures.
Which cartilage forms the 'Adam's apple' in the larynx?
Answer: Thyroid cartilage
The thyroid cartilage is the largest cartilage of the larynx and forms the anterior prominence known as the 'Adam's apple.'
What type of epithelium lines the trachea and primary bronchi?
Answer: Pseudostratified ciliated columnar epithelium
Pseudostratified ciliated columnar epithelium lines the conducting zone airways; its cilia beat to propel mucus and trapped particles toward the pharynx.
The hilum of the lung, where bronchi and vessels enter, is located on which surface?
Answer: Mediastinal surface
The hilum, where bronchi, pulmonary vessels, and nerves enter the lung, is located on the mediastinal (medial) surface of each lung.
Which muscle is the primary muscle of inspiration?
Answer: Diaphragm
The diaphragm is the primary muscle of respiration; its contraction and flattening increases thoracic volume, generating the negative pressure needed for inhalation.
