How does breathing take place? Muscles expand contract in response to pressure and change nerve signals(contcentration of CO2 in tissue speeds up and slows down)
Bronchi Tubes that connect to the lungs
Mucous membranes humidified the air we breath
Larynx Contains voicebox
epiglottis Keeps food and liquids from going into the lungs
