UPDATE 2026
nose - Answers the organ of smell and entrance to the respiratory tract

conchae - Answers fleshy lobes in the nasal cavity which increase its surface area
palate - Answers the upper surface of the mouth that separates the oral and nasal cavities
paranasal sinuses - Answers located in the sphenoid, ethmoid, maxillary, and frontal bones, they
surround the nasal cavity and make the skull lighter; they also serve as resonance chambers for
speech
pharynx - Answers muscular tube extending from the posterior nasal cavity to the esophagus
tonsils - Answers lymphatic tissues on each side of the pharynx that filter air to protect the body from
bacterial invasion
larynx - Answers a cartilaginous structure located beteen the pharynx and trachea; the voice box
epiglottis - Answers a flap of cartilage that covers the windpipe while swallowing

alveoli - Answers tiny sacs of lung tissue specialized for the movement of gases between air and
blood
respiratory membrane - Answers where gas exchange occurs between the air on the alveolar side
and the blood on the capillary side; the alveolar and capillary walls form the respiratory membrane
pulmonary ventilation - Answers Movement of air into and out of the lungs
