The respiratory system
We can not live without the air, It contains oxygen gas which burns the small particles of the digested food to produce energy, carbon dioxide gas and water vapor and this process is called the respiration process .
Human respiratory system
Man needs the respiration process to get the needed energy from the food to do all the body activities as excretion, sensation, reproduction and motion.
The respiratory system provides oxygen for the metabolism in the tissues, It removes carbon dioxide and the waste product of metabolism.
The respiratory system facilitates the sense of smell, it produces speech, it maintains acid-base balance, It maintains body water levels, and it maintains heat balance.
The respiration process takes place in special organs forming the respiratory system , and most organs of exist in the thoracic (chest) cavity. the respiratory system
The respiration process importance
The respiration process gives the body of living organisms the needed energy to do all the body activities, The respiration process is the process by which human obtain energy from the digested food.
Inhalation and Exhalation process.
The inhalation process is a process by which the air rich in oxygen gas enters the lungs, T he exhalation process is a process by which the air rich in carbon dioxide gas and 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.
