WebHemoglobin is comprised of two alpha and two beta proteins and uses iron to facilitate oxygen transportation. Some variations of hemoglobin, such as fetal hemoglobin, contain gamma proteins that changes the shape of the protein. WebRespiratory pressure is always described relative to atmospheric pressure. Atmospheric pressure (ATM) - pressure exerted by all of the gases in the air we breathe (760 mm Hg at sea level) Negative respiratory pressure is less than ATM. Positive respiratory pressure is greater than ATM. Intrapulmonary pressure. WebDiffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.
