On observing , the parts of HUMAN RESPIRATORY SYSTEM are :-

• Part A - Larynx ( Voice box )

• Part B - Right Lung

• Part C - Bronchioles

• Part D - Alveoli ( Alveolus )

These are the main organs of the Respiratory System in Humans .

Larynx in throat produces sounds .

Lungs purify deoxygenated air .

Bronchioles are the passage for oxygen to travel in the body cells .

Alveolis are the place where EXCHANGE OF GASES ( CO2 and O2 ) takes place .
