Question

Using your understanding of diffusion, how do you think oxygen from our lungs is transported to our red blood cells?​

Answer 1

Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, where it binds to hemoglobin. One molecule of hemoglobin can bind four molecules of oxygen (O2).
