In addition to determining pressure/. temperature relationships, you can. compute the amount of steam which will. be condensed by any heating unit of. known Btu output. Conversely, the table. can be used to determine Btu output if. steam condensing rate is known.
Pulmonary ventilation (breathing). Inspiration and expiration-inhale oxygen rich air, exhale carbon dioxide rich air. External respiration. Gas exchange between alveolar capillaries and the alveoli (oxygen movement from the alveoli into the blood, carbon dioxide movement from the blood into the alveoli). Transport of respiratory gases. Oxygen from lungs to tissues, carbon dioxide from tissues to lungs.
Oxygen diffuses from the blood/tissue fluid into cells where it is used in respiration to release energy. Carbon dioxide diffuses back into the blood from cells as it is a waste product made during respiration.Source(s): AS biology student.

Similarly pO2 which is high in concentration in the alveoli coming from outside the blood capillaries diffuses into lungs.
