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.
2. Gas exchange between the alveoli and pulmonary capillaries. A continuous exchange of oxygen and carbon dioxide occurs between the alveoli and pulmonary capillaries, changing the partial pressures of both gases. Oxygen diffuses out of the alveoli into the pulmonary capillaries and carbon dioxide diffuses from the pulmonary capillaries into the alveoli.
