Oxygen transportation step 1 correct answer: Air is inhaled through the process of ventilation (mechanical movement of gas or air into or out of the lungs) Oxygen transportation step 2 correct answer: oxygen diffused from the alveoli into pulmonary capillaries, moving oxygen from the pulmonary veins to the left side of the heart to the aorta into systemic arterial circulation Oxygen transportation step 3 correct answer: Perfusion (exchange of O2 and CO2 in the blood stream, which occurs via the alveoli and pulm capillaries) of the systemic capillaries with oxygenated blood Oxygen transportation step 4 correct answer: oxygen is diffused from the systemic capillaries to each and every cell Gas CO2 transport step 1 correct answer: Diffusion of blood (deoxygenated) from cells into systemic capillaries Gas CO2 transport step 2 correct answer: Perfusion of the systemic capillaries with deoxygenated blood through the venous circulation, to the vena cava into the right side of the heart, to the pulmonary arteries (ART carry deoxygenated blood) Gas CO2 transport step 3 correct answer: Diffusion of th
