What is the function of the cilia in the trachea and bronchi? a. to sweep air into and out of the lungs b. to increase the surface area for gas exchange c. to dislodge food that may have slipped past the epiglottis d. to sweep mucus with trapped particles up and out of the respiratory tract
Which structure is surrounded by rings of cartilage? alveoli pharynx trachea esophagus Peristalsis is a wave of muscular contractions in the esophagus. is the flap of tissue which covers the opening to the trachea. All of these are correct. is the act of swallowing.
Adi S.
Each of the following statements regarding the anatomy of the respiratory system is true EXCEPT: (A) the epiglottis covers the glottis during swallowing to ensure that food does not enter the trachea. (B) the trachea and bronchi are lined by ciliated epithelial cells. (C) the pharynx contains two vocal cords, which are controlled by skeletal muscle and cartilage. (D) the nares are lined with vibrissae, which help filter out particulate matter from inhaled air.
