WHAT IS THE FUNCTION OF THE RESPIRATORY SYSTEM?

THE RESPIRATORY SYSTEM FUNCTIONS TO MOVE OXYGEN FROM THE OUTSIDE ENVIRONMENT INTO THE BODY. IT ALSO REMOVES CARBON-DI-OXIDE AND WATER FROM THE BODY.

WHY DOES OUR BODY NEEDS OXYGEN?

THE ENERGY-REALISING CHEMICALS THAT TAKES PLACE EVERYDAY INSIDE OUR CELLS REQUIRE ENERGY. AS A RESULT OF THESE ENERGY OUR CELLS ARE ABLE TO PERFORM ALL THE TASKS THAT KEEP US ALIVE.

WHAT IS RESPIRATION?

RESPIRATION IS THE PROCESS IN WHICH OXYGEN AND GLUCOSE UNDERGOES A COMPLEX OF SERIES OF CHEMICAL REACTIONS THAT REALEASE THE ENERGY THAT FUELS THE GROWTH AND OTHER CELL PROCESS.

ORGANS IN THE RESPIRATORY SYSTEM

  1. NOSE
  2. PHARYNX
  3. EPIGLOTTIS
  4. LARYNX
  5. TRACHEA
  6. BRONCHUS
  7. LUNGS

ORGANS AND ITS FUNCTIONS

NOSE- THE NOSE ALLOWS US TO BREATHE AND SMELL.

PHARYNX- THE PHARYNX AVTS AS A WAY FOR THE FOOD TO GO TO THE STOMACH AND AIR TO GO TO THE LUNGS.

EPIGLOTTIS- THE FUNCTION OF HE EPIGLOTTIS IS TO BLOCK THE TRACHEA WHILE THE FOOD OR LIQUID GOING DOWN.

LARYNX- IT GUARDS THE PASSAGE TO THE AIRWAYS THAT LEAD TO THE LUNGS.

TRACHEA- THE TRACHEA IS COMMONLY KNOWN AS THE WINDPIPE. IT IS THE AIRWAY THROUGH WHICH RESPIRATORY ORGANISMS PASSES THROUGH.

BRONCHUS- THE FUNCTION OF THE BRONCHUS IS TO SPLIT THE AIR COMMING INTO THE RIGHT AND THE LEFT LUNG.

Bronchi and Lungs

Whenever you smoke, your lungs turn nasty and black. Whenever you are healthy, your lungs are healthy, pink, and good condition. The lungs are the main organs of the respiratory system. Air moves from the trachea to the bronchi, the passages that direct air into the lungs. The left bronchus leads into the right lung. Inside the lungs, each bronchus divides into smaller and smaller tubes in a pattern that resmebles the branches of a tree. At the end of the smallest tubes, are alveoli, tiny sacs of lung tissue whose structure is specialized for the movement of gases between air and blood. - Audrey S.

THE AIR WE BREATHE

THE OXYGEN THAT WE BREATHE COMES FROM THE ATMOSPHERE, WHICH IS A BLANKET OF GAS THAT SURROUND THE EARTH. THE ATMOSHERE IS MADE UP OF MIXTURE OF GAS.
