The function of the respiratory system & the importance of respiration process
The human respiratory system
We can not live without the air, It contains oxygen gas which burns the small particles of the digested food to produce the energy, carbon dioxide gas and the water vapor and this process is called the respiration process.
Man needs the respiration process to get the needed energy from the food to do all the body activities as the excretion, the sensation, the reproduction and the motion.
The respiration process importance
The respiration process gives the body of the living organisms the needed energy to do all the body activities, The respiration process is the process by which the human obtain energy from the digested food.
The inhalation process is a process by which the air rich in oxygen gas enters the lungs, The exhalation process is a process by which the air rich in carbon dioxide gas and the water vapor is expelled outside the body.
The number of respiration times increases when the body is more active to obtain the energy needed for all the body activities.
