29.4 Central and Peripheral Nervous Systems Set up Cornell Notes on pg. 43
Topic: 30.1 Respiratory Functions
•Essential Question: None.
2.1 Atoms, Ions, and Molecules
30.1 Respiratory Functions
KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells.
Drug Essay DUE TOMORROW
30.1 Respiratory and Circulatory Functions
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?
30.1 Respiratory and Circulatory Functions
– picks up oxygen from inhaled air – expels carbon dioxide and water
30.1 Respiratory and Circulatory Functions
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
30.1 Respiratory and Circulatory Functions
• Breathing involves the diaphragm and muscles of the rib cage.
• Air flows from areas of high pressure to low pressure.
Air inhaled.
Muscles contract andrib cage expands.
Diaphragm flattensand moves downward.
Air exhaled.
Muscles andrib cage relax.
Diaphragm relaxesand rises.
30.1 Respiratory and Circulatory Functions
• What happens when areas of the body do not get oxygen?
• What happens when a tourniquet is put on?
30.1 Respiratory and Circulatory Functions
bronchiole
alveoli
Bronchi or Bronchus
Draw and label the parts of the lungs on the bottom of pg 43
trachea
30.1 Respiratory and Circulatory Functions
On pg. 42 set up a respiratory system tree map describing the functions of each…• Nose & mouth• Epiglottis• Trachea • Lungs• Bronchi• Bronchioles• Alveoli bronchi

Parts and Functions of the Respiratory system (4m22s)
• Add notes from the video to your tree map
– Nose– Epiglottis– Trachea– Bronchi– Bronchioles– Alveoli
30.1 Respiratory and Circulatory Functions
On pg. 42 make a respiratory system tree map describing the functions of each…• Nose & mouth• Epiglottis• Trachea • Lungs• Bronchi• Bronchioles• Alveoli bronchi
alveolibronchioles
• Focus on FUNCTION!
• 910-912
30.2 Respiration and Gas Exchange
• Review your tree map with your table.• Be ready to share (random)
bronchi
alveolibronchioles
30.1 Respiratory and Circulatory Functions
• 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
