Respiratory System
Challenge ?• People from sea-level
usually experience increased respiration when they go to high elevations.
Explain why?
Connection (Remember all answers need units)
• The average person breathes about 12 times/min. How many breaths does the person take in a day? (Show your work)
• The average person breathes 8640 liters of air per day. (Show your work)– How many liters is that every hour?
– How many liters every minute?
Vocabulary
• Respiration• Breathing• See Objective Notes #1

OBJECTIVES (pg. 556) NOTES
Identify and describe the parts and functions of the respiratory system
• Nose – Primary passageway in/out of respiratory system; warms, moistens and cleans air
• Pharynx – Throat – 2 branches, one to lungs other to digestive system
• Larynx- voice box, produces sound• Trachea- windpipe , passageway from throat to lungs• Bronchi – trachea splits in two, passageway to each lung• Lungs- sack like organ – air exchange• Alveoli – tiny sack like organ this is where the actual gas
exchange takes place• Diaphragm – thick wall of muscle below lung, contracting and
relaxing this muscle forces air in and out of lungs
Describe the flow of air through the respiratory system
See # 5-10 of Guided Notes
Describe the relationship between the respiratory system and cardiovascular system
• The circulatory system is the transport system that carries materials that are imported and exported by the respiratory system(lungs, nose, mouth)to and from the cells.
