1. In the above diagram C arteriol blood which carries oxyginated blood from left vetricle to body parts, The partial pressure PO2 is 80-100 and partial pressure of PCO2 is 40. 2.E represents veinus blood, which carries deoxyginated blood from tissues to heart. The partial pressure PO2 is 40-50 and partial pressure of CO2 PCO2 is 45. 3. Hyberbaric setting are used in medical treatment in which ambient pressure is greater than sea level. It is used in hyberbaric oxygen theraphy. 4. This helps to increase the higher of concentration of oxygen in tissues. But higher pressure of xygen may cause toxicity. It causes temporary blurred vision. B. Differece in Partial pressure gradient between alveolar air and pulmonary capillary blood, and systemic capillary blood and surrounding tissue. Ability of oxygen to bind haemoglibin is called affinity for oxygen. Fetal haemoglobin has more greater affinity to oxygen. Solution 1.
