Gas exchange between atmosphere, blood, and body cells
Air flow INTO lungs
Air flow OUT of lungs
What is Pulmonary Respiration?
Gas exchange between RESPIRATORY MEMBRANE
What is Tissue Respiration?
Gas exchange between BLOOD and TISSUE CELLS
What is Cellular Respiration?
Metabolic reaction of O2 and CO2 exchange in the production of ATP
Which 2 structures are involved in the Upper Respiratory System?
Which 4 structures are involved in the Lower Respiratory System?
Larynx (Voice box)
Which 7 structures are involved in the Conducting Zone?
Larynx (Voice box)
What is the function of the Conducting Zone?
Filters/moisten air for lungs
Receive olfactory stimuli

What is the function of the Respiratory Zone?
What is the function of Ciliated Cells in the Nose?
Moves mucous down to the Pharynx for digestion
Describe the structure and location of the Pharynx (Throat).
Funnelled tube behind Nasal Cavity and above Larynx
What are the functions of the Pharynx (Throat)?
Passageway for air and food
Chamber for sounds
Inferior to the Pharynx, it opens into the _________ posteriorly, and the ________ anteriorly.
Esophagus / Larynx
Where is the Larynx located?
