Respiratory System Flashcards
Primary functions
o provide oxygen to body tissues for cellular respiration
Remove the waste product carbon dioxide
Help to maintain acid-base balance
Secondary functions
Sensing odors
Speech production
Straining (during childbirth or coughing)
Conducting Zone
Moves air in/out of the lungs
Respiratory Zone
part of the airway where gas exchange takes place
Nose
The major entrance and exit for the respiratory system
Pharynx
The human pharynx (plural: pharynges) is the part of the throat situated immediately posterior to the mouth and nasal cavity, and superior to the esophagus and larynx.
Larynx
the cartilaginous structure that connects the pharynx to the trachea and helps regulate the volume of air that enters and leaves the lungs. The larynx is also involved in sound production and protecting the trachea against food aspiration.
Trachea
is a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.
Alveolar duct
s a tube composed of smooth muscle and connective tissue, which opens into a cluster of alveoli.
Alveolus
is one of the many small, grape-like sacs that are attached to the alveolar ducts.
Alveolar sac
is a cluster of many individual alveoli that are responsible for gas exchange.
Boyle’s Law(Formula)
P1V1 = P2V2
Boyle’s Law (text explanation)
Pressure and volume are inversely related.
Inspiration
when we breath in
Expiration
when we breath out
