SHORT AND LONG TERM EFFECTS OF EXERCISE ON THE RESPIRATORY SYSTEM

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.

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

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.
