hey mate this is your answer:
firstly air enters ( oxygen ) into our mouth through nasal passage this oxygen then passed to lungs in dissolved form after this the capillaries or alveoli attached to the blood vessels sent carbon dioxide (i.e. from deoxygenated blood ) to lungs where this again sent to nasal passage and we breathe out...
hope it helps
thanks

Answer:
The exchange of gases occurs as a result of diffusion down a concentration gradient. Gas molecules move from a region in which they are at high concentration to one in which they are at low concentration. Pulmonary ventilation provides air to the alveoli for this gas exchange process. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. That is, oxygen moves into the blood by diffusion and combines with the haemoglobin in red blood cells to form oxyhaemoglobin.
I hope it helps you!
