5.REMAINS FOOD NOT ABSORBED CONTINIOUS TO LARGE INSTESTINE, THERE WATER IS ABSORBED AND REMAINS TRANSFORMED INTO FAECES, WAIT IN THE RECTUM TO BE EXPELLED THROUG ANUS
RESPIRATION
TAKE OXYGEN CELLS NEED TO TRANSFORM ENERGY, BODY RELEASES CO2 DOESN'T NEED
PULMONARY VENTILATION
INHALATION
- AIR ENTERS BODY TROUGH NOSTRILS WHERE IS WARMED AND CLEANED IMPURITIES BY MUCUS AND FINE HAIRS IN NASAL CAVITY
2.AIR TRVELS TROUGH LARYNX INTO WINDPIPE, INTO BRONCHI AND BRONCHIOLES, FINALLY REACHES LUNGS NOW FILLED WITH AIR
EXHALATION
DIAPHRAGM RELAXES, CAVITY CONTRACTS, LUNGS DEFLATE, AIR GOES TROUGH VRONCHIOLES, BRONCHI, WINDIPIPE AND LARYNX, AND LEAVES BODY TROUGH NOSTRILS
HOW AIR TRAVELS BODY
- AIR ENTERS BODY TROUGH NOSTRILS
2.AIR TRAVELS DOWN LARYNX, WINDPIPE, BRONCHI, BONCHIOLES, FINALLY REACHES LUNGS
-
GAS EXCHANGE
GAS EXCHANGE OCCURS IN ALVEOLI,IN PROCESS OXYGEN FROM OUTSIDE PASSES INTO BLOOD AND CARBON DIOXIDE PASSES TO LUNGS AND LEAVES BODY
CIRCULATORY SYSTEM
TRANSPORTS NUTRIENTS OXYGEN TROUGH BLOOD TO CELLS, AND HELPS THEM GET RID WASTE PRODUCTS
BLOOD
PLASMA: FLUID BLOOD CELLS FLOAT, CARRIES NUTRIENTS WASTE PRODUCTS
-
BLOOD VESSELS
CAPILLARIES: CONNECT ARTERIES AND VEINS, ALLOW EXCHANGES GASES SUN¡BSTANCES IN CELLS
