Yes, when we breathe in, oxygen from the air enters our lungs. This oxygen is then absorbed into the bloodstream through tiny air sacs in the lungs called alveoli.
Oxygen enters the blood in the alveoli of the lungs
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
Oxygen enters the blood stream through the air sacs in you lungs.
