Detailed explanation-1: -Oxygen gets into the blood through tiny blood vessels around the alveoli. Red blood cells pick up the oxygen and deliver it to the body’s cells.
Detailed explanation-2: -When you breathe in (inhale), air containing oxygen enters your windpipe, passes through the bronchi and eventually reaches the air sacs. These air sacs, called alveoli, are responsible for gas exchange. They look a bit like grapes at the end of the bronchial branches.
Detailed explanation-3: -Summary. Oxygen enters the lungs, then passes through the alveoli and into the blood. The oxygen is carried around the body in blood vessels. Carbon dioxide moves into the blood capillaries and is brought to the lungs to be released into the air during exhalation.
