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?

• The respiratory system is where gas exchange occurs.

– What are the gases involved with the respiratory system?


– 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 andrib cage expands.

Diaphragm flattensand moves downward.

Air exhaled.

Muscles andrib cage relax.

Diaphragm relaxesand rises.


• What happens when areas of the body do not get oxygen?

• What happens when a tourniquet is put on?

alveoli

Bronchi or Bronchus

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

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 bronchi

• Focus on FUNCTION!

30.2 Respiration and Gas Exchange

• Review your tree map with your table.• Be ready to share (random)

bronchi

alveolibronchioles


• 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
