nostrils
nasal cavity
turbinates
pharynx
larynx
three parts of the lower respiratory system
trachea
bronchi
lungs
external respiration involves the _____
lungs
internal respiration involves the _____
tissues
what kind of stimulation decreases mucus production
sympathetic stimulation
what kind of stimulation increases mucus production
parasympathetic stimulation
what kind of stimulation dilates smooth muscle in the walls of the bronchioles
sympathetic stimulation
what kind of stimulation constricts smooth muscle in the walls of the bronchioles
parasympathetic stimulation
four functions of the respiratory system
Gas exchange (oxygen and CO2)
Acid-base balance
Thermoregulation
Voice production
four respiratory mechanisms of action
ventilation
distribution
diffusion
perfusion
moving air in and out of the lungs
ventilation
Moving air throughout the lungs
distribution
movement of gas across alveolar membranes
diffusion
supply of blood to the alveoli
perfusion
three body defense mechanisms by respiration
nasal cavity
reflexes
mucocilliary
