BIOC34H3 : study guide
Document Summary
Lecture 11 study notes (slide 25 onwards) and lecture 12. Slide 26 (lecture 11: hypoxia: decreased inspired oxygen, hyperoxia: increased inspired oxygen, normoxia: normal inspired oxygen, hypocapnia: decreased inspired carbon dioxide, hypercapnia: increased inspired carbon dioxide, normocapnia: normal inspired carbon dioxide. Slide 27: gas concentration = partial pressure x k, k = solubility co-efficient, when calculating partial pressure, if relative humidity is not zero, you must subtract it from the partial pressure of the gas in question. perfusion limitation: limiting factor that gets oxygen to tissues is rate of which blood is flowing from pulmonary circulation to the tissues. The blood gets oxygen to the tissues, and gets rid of carbon. possibly because athletes can become diffusion limited, meaning they cannot utilize any more oxygen due to the max blood already been in use. Slide 4: apnea: absence of breathing, hence sleep apnea: absence of breathing while sleeping, dyspnea: laboured breathing or shortness of breath.
