What happens to respiratory process in man going up a hill ?

As altitude increases, the oxygen level in the atmosphere decreases. Therefore, as a man goes uphill, he will suffer from oxygen deficiency. This causes the amount of oxygen in the blood to decline. The respiratory rate increases to compensate for the decrease in the oxygen level of blood. Simultaneously, the rate of heart beat increases to increase the supply of oxygen to blood.
