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.
Report Abuse. 1  The most gas exchange occurs in the capillaries as the pressure there is low. The hemoglobin (protein in the red blood cells) is more loosely bonded to oxygen where the pressure is lower. 2  Gas Exchange occurs in the capillaries that branch off from the arteries. The capillaries touch cells and oxygen inside blood cells exit the capillary and enter the body cell while carbon dioxide exits the body cell, travels through the capillary wall and enters the blood cell.
