Bone and soft tissue that separeates teh cavites is? Nasal Septem
Goublet cells produce______. Nasal Mucosa
3 curly bones on each lateral wall, Superior, middle and inferior. Nasal Conche
Olfactory receptors are aka Chemo receptors
Air filled cavities in the frontal, maxillae, ethmoid and sphenoid bones. Paranasal Sinuses
Muscular tube posterior to the nasal and oral cavites. Pharynx
how many parts does the pharynx include? 3 parts, Nasopharynx, oropharynx, laryngopharnx
Seperates oropharynx and nasopharynx Soft Palate
Punching bag on the soft palate uvula
Passes air and food. Oral Pharynx
Lingual Tongue
Inferior, together with oropharynx this innitiates swallowing
Voice box larynx
cartilage that lowers to close passage to larynx while swallowing Epiglottis
vibrate to make sound waves Vocal Chords
"wind pipe" Trachea
no cartalidge Terminates at alvoli, circular smooth muscle Bronchole
Lateral to heart, rests on diaphragm Lungs
Level with Clavicle Apex
the 3 pleural membranes are Sirus membranes, parietal, and visceral
millions of tiny air sacs within the lung Avoli
How many cell types do avoli have? 2,
which type of avoli cell produces pulmonary sufactant? Alveolar type II cells
What does surfactant do? Prevents walls and alveoli from sticking togetehr by decreasing surface tension.
What is within the alveoli? Macrophages
