Imagine that you have just been running or exercising strenuously Imagine that you have just been running or exercising strenuously. Please give examples of what happens to your body. How do you feel? Heart? Lungs? Chest?

KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells.
The respiratory system is where gas exchange occurs. What are the gases involved with the respiratory system? nose sinus mouth epiglottis trachea lungs
picks up oxygen from inhaled air expels carbon dioxide and water
The respiratory system moves gases into and out of the blood. It is the only place where gases in the blood are exchanged with gases from the atmosphere
Breathing involves the diaphragm and muscles of the rib cage. Air flows from areas of high pressure to low pressure. Air inhaled. Muscles contract and rib cage expands. Diaphragm flattens and moves downward. Air exhaled. Muscles and rib cage relax. Diaphragm relaxes and rises.
What happens when areas of the body do not get oxygen? What happens when a tourniquet is put on?
Draw and label the parts of the lungs on the bottom of pg 43 Bronchi or Bronchus trachea bronchiole alveoli
Respiratory System Overview (3m4s)
On pg. 42 set up a respiratory system tree map describing the functions of each… Nose & mouth Epiglottis Trachea Lungs Bronchi Bronchioles Alveoli bronchi alveoli bronchioles
Parts and Functions of the Respiratory system (4m22s) Add notes from the video to your tree map Nose Epiglottis Trachea Bronchi Bronchioles Alveoli
On pg. 42 make a respiratory system tree map describing the functions of each… Nose & mouth Epiglottis Trachea Lungs Bronchi Bronchioles Alveoli Focus on FUNCTION! 910-912 bronchi alveoli bronchioles
Review your tree map with your table. Be ready to share (random) bronchi alveoli bronchioles
Functions of the parts of the respiratory system Nose and mouth are entry points Epiglottis regulates airflow into the trachea- and keeps food from blocking the airways Trachea is the major airway to the lungs Lungs are organs that absorb oxygen and exhale carbon dioxide Bronchi are bronchioles are airways to the alveoli **Alveoli are main sites of gas exchange; absorb oxygen
