How does oxygen move from the lungs into the bloodstream? O It is pumped from the alveoli into the bloodstream O It flows through special oxygen-gated channels O It diffuses across the alveolar membrane down its concentration gradient O Oxygen transport proteins shuttle the oxygen molecules across the membrane O It doesn't - it mostly moves from the bloodstream into the lungs
