1. Respiratory System
In Class Notes:

2. Function: (30.5) Function of the respiratory system
Provide oxygen for distribution to cells through the body
removes waste products and carbon dioxide from the body

3. Organs Involved: (30.5) Organs involved and the function of each
Pharynx= where the passageways of air and food cross
Epiglottis= covers the air pathway and provides water/food from entering when needed
Larynx= voice box
Trachea= windpipe
Bronchi= air tubes that connect the long and trachea
Lungs= function in the exchange of oxygen and carbon dioxide within the blood
Bronchiole= thin tube that branches a bronchus within a lung
Diaphragm= plays a key role in breathing

4. Sequence of breathing:
Explain the process of a complete breath:
Inhale; diaphragm and rib muscles contract
increase in lung volume, reducing air pressure within the alveoli
Air moves from higher pressure to lower pressure-from mouth/nose filling the aveoli

5. Diagram:
