Summary Introduction
Introduction:
The oxygen and carbon dioxide are respiratory gases. The two sites of the respiratory gas exchange are alveoli and the tissues. The blood is the medium which transports the gases from the alveoli to the cells.

A drop in the [H+] of blood plasma would lead to a decrease Hb affinity for O₂. An increase in the partial pressure of CO₂ in the tissues would lead to a decrease Hb affinity for O₂- If you inhaled CO for an extended period of time, at partial pressures 1000 fold higher than normal indoor atmospheric pressure, your body would have a difficult time delivering oxygen to your tissues. When the partial pressure of oxygen is low within the atmosphere, your body responds by increasing the biological activity of Hb's negative effectors.arrow_forwardAn individual's ratio of carbonic acid and bicarbonate ions is 17/0.6 Which of the following is a true statement?
