1. Respiratory System

2. Challenge ? People from sea-level usually experience increased respiration when they go to high elevations. Explain why?

3. 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?

7. 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.
