Question
what are the steps that a molecule of oxygen must take from your living room to your ckin cells?

Answer
Hi logan
When you breath in the molecule passes through the bronchi to the alveoli of the lungs.  It then diffuses into a capillary and is carried to the left atrium of the heart, to the left ventricle, to the aorta and other vessels.  If it is going to the skin of the arm it will follow the brachial artery and eventually in the capillaries of the skin.
