Respiratory System The primary function is to provide O2 for and remove CO2 produced by cellular respiration 1. Intro a. What is Cellular Respiration -the production of ATP withing the cell -O2 + food (glucose) H2O + ATP + CO2 -45kg (100lb) of ATP formed per day -300L of CO2 per day 2. Parts a. Upper Respiratory Tract -consists of nasal and paranasal cavities, pharynx, and larynx -nose and throat b. Lower Respiratory Tract (LRT) -trachea, bronchial tree, and lungs (pleural cavity) 3. The Alveoli -serve as the respiratory exchange surfaces -there are approximately 500,000,000 alveioli in the lungs -this increases the lungs surface area to 450ft^2 The Tracheobronchial Tree 1. Consists of 3 layers: 1. Mucosa 2. Submucosa 3. Adventitia -the tree is frequently wrapped by smooth muscle, but it is not considered a permanent later -the tracheobronchial tree divides 23x before leading to alveoili 2.
