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.
The capillaries near the alveoli contain blood low in oxygen and high in CO2. As the blood passes the alveoli gaseous exchange occurs. Oxygen from the alveoli diffuses into the blood in the capillaries and CO2 diffuses out of the blood into the alveoli then it is breathed out.
