    Alveoli is the site for the gas exchange in the respiratory system of humans. Gas exchange occurs due to the gradient in the partial pressure of gases. During the process, the partial pressures of oxygen in alveoli is found to be

    Read the following statement . a) High H^+ concentration and higher temperature are favourable for dissociation of oxygen from oxyhaemoglobin. b) Partial pressure of oxygen in alveoli is higher than in tissue . c) The maximum volume of air a person can breather in after a forced expiration is vital capacity. d) In alveoli PCO_2 low and PO_2 high are for dissociation of CO_2 from carbamino haemoglobin . How many of the above statement are true ?

    At high altitudes the partial pressure of oxygen is less than that at the ground level. This leads to
