input question: What is the missing first step of the following process:  -  Air is transported to the lungs - Air reaches the alveoli, the smallest air sacs in the lungs - In the alveoli, air passes into the blood within small capillaries - The gaseous oxygen in the air dissolves into the capillary blood - The dissolved oxygen is picked-up by red blood cells - The red blood cells bind the oxygen via a protein called heme - Red blood cells circulate throughout the body and reach the various tissues - Within small capillaries, the heme release the oxygen - The oxygen can then reach the cells within the tissue -???
