The biggest difference betweent an optometrist and an opthamologist is that an opthamologist is a medical doctor. Opthamologists has gone to medical school and then specialized in opthamology which covers all aspects of eye care including diagnosis, treatment and surgery. An Optometrist has received training in the areas of examining the eyes for diagnosing and treating visual or eye health, prescribing corrective lenses and treating limited eye diseases non-surgically. An optometrist is a doctor who works with your eyes and prescribes glasses and/or contacts, and an opthamologist is also someone who works with your eyes, but only for surgeries and corrective eye treatments.
Gas exchange occurrs in all organisms, but judging by the category this question placed in, I am making the assumption that this question is asking about gas exchange in humans. Humans use lungs for gas exchange. The lungs are two internal "sac-like" organs. The lungs are able to expand and contract becuase of the alveoli. Alveoli are small cavities/air sacs in the lungs. The lungs are connected to the outside air by way of a system of tubular passageways; the trachea, bronchi and bronchioles. Each lung is divided into a number of lobes, each recieving its own bronchus. Each bronchus divides many times into bronchioles, which then end in many alveole ducts and alveoli. These provide a very large surface area for the exchange of respiratory gases by diffusion betweent he alveoli and the blood in the capillaries. Gas exchange occurs in two stages of ventillation, called inhilation and exhilation. Inhilation is when the intercostal muscles contract, which causes the ribcage to expand and move up, and the diaphragm then contracts and moves down. This action causes the thoraic voume to increase, which allows the lungs to expand and this decreases the pressure inside them. Air is then pulled in from the atmosphere is response to this pressure gradient. The cardiovascular system then participates by transporting the respiratory gases to and from the cells of the body. In the second stage of ventilation, exhilation, the intercostal muscles and diaphragm relax. and gravity pulls the ribcage down. The lungs then recoil, which decrease the volume inside and therefore increases the pressure. The air then flows out of the lungs to equalize with the air pressure outside of the lungs, and with it we release carbon dioxide. So to summarise: We breathe in O2 when the lungs expand, and we release CO2 when the lungs contract.
