First, O2 is lipid soluble and crosses cell membranes without the aide of membrane transporters. Second, the free movement across cell membranes relies on a partial pressure gradient for diffusion according to Fick’s law. When O2 reaches the alveolar capillary blood, it diffuses into erythrocytes and bonds to hemoglobin where the interaction is governed by the oxyhemoglobin dissociation curve.
