Respiratory System

• The trachea is the windpipe, which connects to the larynx.
• The major function is gas exchange, supply body with O2 and needs to dispose of CO2
• Conduction Zone: warms, humidifies, and filters air as it travels to the respiratory zone
• Air enters nose through nostrils and is warmed when it passes through nasal cavity
• What is the purpose of the epiglottis?

  Prevents food from going down larynx when you swallow.
• What is the structural difference between the right/left lungs?

  Right: 3 lobes Left: 2
• Where does MAJORITY of gas exchange occur?

  In the alveoli
• What is known as the voice box?


  Larynx
• What is #1

  Trachea

  
• What is #2?

  Right lung

  
• What is #3 and what does it do?

  When the diaphragm contracts, the volume in the lungs increases, so pressure decreases and air moves in.

  
• What is #4?

  Brionchioles

  
• What is #5?

• The amount of air that remains in your lungs is known as the Residual volume
• The amount of air you regularly breathe is your Tidal volume
• The Inspiratory reserve volume measures the max amount of air you could forcibly inhale
• The expiratory reserve volume is the maximum amount of air you can forcibly exhale
• The total amount of exchangeable air you have is the vital capacity.
• Your lungs move when the diaphragm contracts
• As the diaphragm relaxes, the volume in your lungs decreases, so pressure increases, and air moves out.
• The overall purpose of breathing is to provide oxygen to our cells for cellular respiration
• The roles of ureters are to transport urine from the kidneys to the bladder
• The role of the bladder is to store urine and empty it into the urethra
• The role of the urethra is to transport urine from the bladder to the exterior of the body
