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.
