The function of the respiratory system and 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 the respiration times increases when the body is more active to obtain the energy needed for all the body activities .
