external respiration वाक्य

The external respiration system uses the lungs and a much larger series of air sacs distributed throughout the body so that the oxygen supply communicates directly with body parts.
"' Oxygen equivalent "'compares the relative amount of oxygen available for respiration at a variable pressure to that available at SATP . As external respiration depends on the exchange of gases due to partial pressures across a semipermeable membrane and normally occurs at SATP, an oxygen equivalent may aid in recognizing and managing variable oxygen availability during procedures such as hyperbaric oxygen therapy or medical air transport.
