Question

What happens to the respiratory system process in a man going up a hil?

Answer 1

Answer: LESS OXYGEN

Explanation:        As altitude increases, the oxygen level in the atmosphere decreases. Therefore, as a man goes uphill, he gets less oxygen with each breath. ... Simultaneously, the rate of heart beat increases to increase the supply of oxygen to blood.

Answer 2

$\huge\underline\mathbb\pink{{♡ANSWER♡}}$

$\red\longmapsto\:$ As altitude increases the pO2 in the atmosphere decreases.

$\red\longmapsto\:$ When a man goes up a hill he gets less oxygen with every breath .

$\red\longmapsto\:$ The rate of respiration increases in response to decrease in the oxygen content in the blood.

$\red\longmapsto\:$ Simultaneously the rate of heart beat increases to increase the supply of oxygen to blood.
