Respiratory system

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 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 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 the speech, it maintains acid-base balance, It maintains the body water levels, and it maintains the heat balance.

The respiration process takes place in special organs forming the respiratory system, and the most organs of the respiratory system exist in the thoracic (chest) cavity.

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.

Respiratory system

Inhalation and Exhalation process.

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.
