FUNCTIONS: 1. TRACHEA THE MAIN TRUNK OF THE SYSTEM BY WHICH AIR
PASSES TO AND FROM THE LUNGS 6. PARTS AND FUNCTIONS: 2. BRONCHI THE
MAIN BRONCHUS THAT IS CONNECTED TO THE TRACHEA THAT SEPARATES THE
LEFT AND RIGHT LUNG. 7. PARTS AND FUNCTIONS: 3. BRONCHIOLES THE
SECONDARY THIN-WALLED BRANCH OF A BRONCHUS THAT SERVES AS THE
LITTLE PASSAGEWAYS OF AIR TO ENTER THE ALVEOLI. 8. PARTS AND
FUNCTIONS: 4. ALVEOLI SMALL AIR-CONTAINING COMPARTMENTS OF THE
LUNGS IN WHICH THE BRONCHIOLES TERMINATE AND FROM WHICH RESPIRATORY
GASES ARE EXCHANGED. 9. PARTS AND FUNCTIONS: 5. NOSE THE PART OF
THE HEAD WHERE HUMANS SMELL AND BREATHE. 10. PARTS AND FUNCTIONS:
6. NASAL CAVITY ONE OF THE TWO OPENINGS OF THE NOSE. 11. GUIDE
QUESTIONS AND ANSWERS 12. Q1. WHAT DOES EACH PART OF THE BUNCH OF
GRAPES MODEL REPRESENT IN RELATION TO THE BREATHING SYSTEM? ANSWER:
THE GRAPES REPRESENT THE ALVEOLI, THE SMALLEST STEMS REPRESENT THE
BRONCHIOLES, THE LARGE STEMS REPRESENT THE BRONCHI AND THE LARGEST
STEM REPRESENTS THE TRACHEA. 13. Q2. HOW WILL YOU DESCRIBE THE
PATHWAY OF OXYGEN IN THE BREATHING SYSTEM? ANSWER: THE AIR ENTERS
THE MAIN BRANCH (TRACHEA) THEN TO THE SMALLER STEMS (BRONCHI) AND
FINALLY TO THE SMALLEST STEMS (BRONCHIOLES) THAT WILL LATER GO ON
TO THE ALVEOLI. 14. Q3. WHAT WILL HAPPEN IF ONE PART OF THE STEMS
FAIL TO CARRY OUT ITS FUNCTION PROPERLY? ANSWER: THE GASES WILL
NEVER BE BROUGHT INTO THE BODY SYSTEMS AND OBVIOUSLY, AN ORGANISM
WILL LATER DIE. 15. INFERENCE ABOUT THE TOPIC: THE AIR WE BREATHE
GOES THROUGH THE NOSE AND THEN THROUGH THE TRACHEA OR WINDPIPE
WHICH SEPARATES INTO TWO BRANCHES CALLED BRONCHIAL TUBES OR
BRONCHI, ONE ENTERING EACH LUNG.THE BRONCHI SUBDIVIDE MANY TIMES
INSIDE THE LUNGS ANALOGOUS TO THE BRANCHING PATTERN OF GRAPES
FINALLY BECOMING HAIR LIKE TUBES CALLED BRONCHIOLES . IN THE LAST
PART OF THE TERMINAL, BRONCHIOLES ARE TINY BUBBLE- LIKE BUNCH OF
STRUCTURES CALLED ALVEOLI OR AIRSACKS.
