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 is released from the mitochondria as a product of cellular respiration. B. Carbon dioxide diffuses from the alveoli into surrounding capillaries. C. As oxygen diffuses from the lungs into capillaries, blood becomes deoxygenated. D. Oxygen diffuses from large blood vessels into the body's cells. E. In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells. E.  When oxygen diffuses from the alveoli to the surrounding capillaries, it enters a red blood cell and binds to hemoglobin.
