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.
Movement of oxygen into the blood. Diffusion of oxygen into the blood takes place at the alveoli (air sacs). The air in the alveoli contains a lot of oxygen. The alveoli are very close to capillaries, which are small blood vessels. The blood in the capillaries has very little oxygen and has a lot of carbon dioxide. The walls of both the alveoli and the capillaries are very thin and oxygen and carbon dioxide molecules can move through these walls.
