Lung Volumes and Capacities A. Anatomical dead space - the conducting zone of the lung that does not have a respiratory function. The average anatomical dead space is 150 ml. C. Tidal volume - normal volume of inspiration and expiration breathing. Resting TV averages 500 ml. Ventilation A. Ventilation - the product of tidal volume and breathing frequency.
Flow is directed due to differences in pressure between the air in the lungs and atmospheric air.
C. Surfactant - a fluid in the lungs that functions to lower the surface tension of the alveoli, thereby decreasing the resistance to inflation. D. Compliance - the property of being able to increase size or volume with only small changes in pressure. E. Respiration - the process of gas exchange. Hemoglobion - specialized protein located on the surface of red blood cells that function to transport oxygen. Haldane Effect - the PO2 effect on the blood's ability to store carbon dioxide.
