1. SHORT AND LONG TERM EFFECTS OF EXERCISE ON THE RESPIRATORY SYSTEM

2. THE RESPIRATORY SYSTEM HAS TWO MAIN FUNCTIONS: THE RESPIRATORY SYSTEM HAS TWO MAIN FUNCTIONS: THE RESPIRATORY SYSTEM HAS TWO MAIN FUNCTIONS: TO GET O2 INTO THE BODY TO GET O2 INTO THE BODY TO GE CO2 OUT OF THE BODY TO GE CO2 OUT OF THE BODY REVISION FROM LAST LESSONEXPLAIN INSPIRATION AND EXPIRATION. HAND OUT DIAGRAM TO SHOW RIB MOVEMENT AND THE EXPAIN IN OWN WORDS – THIS MAY NEED TO BE FINISHED OF FROM LAST LESSON. REVISION FROM LAST LESSONEXPLAIN INSPIRATION AND EXPIRATION. HAND OUT DIAGRAM TO SHOW RIB MOVEMENT AND THE EXPAIN IN OWN WORDS – THIS MAY NEED TO BE FINISHED OF FROM LAST LESSON.

3. TASK WRITE DETAILED NOTES ON ALVEOLI AND THE CONTENT OF THE AIR – THIS CAN BE DONE IN THE FORM OF A TABLE.

4. NOTES SHOULD INCLUDE THE FOLLOWING: NOTES SHOULD INCLUDE THE FOLLOWING: NOTES SHOULD INCLUDE THE FOLLOWING: THE LINING OF THE ALVEOLI IS COVERED WITH A FILM OF MOISTURE.THE O2 CONCENTRATION IN THE BLOOD IS LOWER THAN IN THE ALVEOLI, HENCE THE O2 IN THE AIR SPACE DISSOLVES IN THE FILM OF MOISTURE AND DIFFUSES THROUGH THE EPITHELIUM, AND THE CAPILLARY WALL, THE PLASMA INTO A RED CELL, WHERE IT COMBINES WITH HAEMOGLOBIN. THE CAPILLARIES REUNITE AND EVENTUALLY FORM THE PULMONARY VEINS WHICH RETURN THE OXYGENATED BLOOD TO THE LEFT ATRIUM OF THE HEART. THE LOW CONCENTRATION OF CO2 IN THE ALVEOLI STIMULATES THE ENZYME, CARBONIC ANHYDRASE, IN THE BLOOD TO BREAK DOWN THE BICARBONATE SALTS AND LIBERATE CO2. THIS GAS DIFFUSES INTO THE ALVEOLI AND IS EVENTUALLY EXPELLED.

5. TASK WHAT ARE THE SHORT TERM AND LONG-TERM EFFECTS ON THE RESPIRATORY SYSTEM? WHAT ARE THE SHORT TERM AND LONG-TERM EFFECTS ON THE RESPIRATORY SYSTEM? SHORT-TERM INCL. SHORT-TERM INCL. BREATHING QUICKENS AND DEEPENS BREATHING QUICKENS AND DEEPENS BUILD UP OXYGEN DEPT BUILD UP OXYGEN DEPT

6. EXPERIENCE THE OXYGEN DEPT RUN ON THE SPOT FOR 1 MIN AS FAST AS YOU CAN AND EXPAIN TO YOUR PARTNER WHAT IS HAPPENING RUN ON THE SPOT FOR 1 MIN AS FAST AS YOU CAN AND EXPAIN TO YOUR PARTNER WHAT IS HAPPENING

7. LONG-TERM IMPROVED EFFICIENCY OF THE LUNGS IMPROVED EFFICIENCY OF THE LUNGS CARBON DIOXIDE REMOVED MORE EFFICIENTLY CARBON DIOXIDE REMOVED MORE EFFICIENTLY VITAL CAPACITY IS INCREASED VITAL CAPACITY IS INCREASED MORE ALVEOLI FOR GASEOUS EXCHANGE MORE ALVEOLI FOR GASEOUS EXCHANGE VO2 (AEROBIC CAPACITY) IS INCREASED VO2 (AEROBIC CAPACITY) IS INCREASED MORE CAPILLARIES AROUND ALVEOLI MORE CAPILLARIES AROUND ALVEOLI

8. HOMEWORK WHAT ARE THE EFFECTS OF SMOKING ON THE ALVEOLI AND GASEOUS EXCHANGE? WHAT ARE THE EFFECTS OF SMOKING ON THE ALVEOLI AND GASEOUS EXCHANGE?
