Respiration::
- Is the vital process which provides the body with energy and getting rid of harmful substances as carbon dioxide and water vapour
- Equation of respiration process :
- Importance of respiration:
- All living organisms need energy to perform their vital activities so they must respire to obtain this energy by burning food .
- The Respiratory system
- It is the system which provides the body of the living organism with oxygen and getting rid of carbon dioxide and water vapour .
The structure of human respiratory system
- The human respiratory system consists of:
- The nose
- Pharynx
- Larynx
- Trachea
- Bronchi
- Two lungs
Mechanism of breathing:
Inhalation process:
Is the process by which air rich in oxygen enters the lungs
Exhalation process:
Is the process by which air carries carbon dioxide and water vapour comes out of the lungs.
Exchange of gases in the two lungs:
- The lung consists of alveoli "air sacs "surrounded by blood capillaries.
- During Inhalation:
- Air containing oxygen enters to the alveoli in the lungs .
- The exchange of oxygen and carbon dioxide takes place between the alveoli and capillaries where:
_ Oxygen from the air diffuses through the alveoli into the blood
- This blood is carried to all the cells of the body to be used in food burning to release energy, water vapour and carbon dioxide.
- During Exhalation:
- Carbon dioxide from the cells diffuses out of the blood into the alveoli .
- The exhaled air containing carbon dioxide and water vapour passes from the lungs up through the trachea and out of the body
The hygiene of respiratory system
*Some diseases that attack the respiratory system :
- Lung irritation
- Tuberculosis
- Influenza
Methods of infection:
1- Through microbes contaminated air
2- The direct connection to the patient
3- Using the patient's personal tools.
Instructions should be followed on attacking the respiratory system:
1- use the medicines which described by the doctor
2- The patient should rest in the bed
3- The food must contains vitamins and minerals .
Methods of protection from respiratory system diseases :
1- stay away from sick people .
2- keeping away from crowded bad aerated places
3- Avoid smoking and smokers
4- Avoid exposing to direct current of air.
** How can we keep the respiratory system healthy?
1- We should breath in through the nose not through the mouth
2- Practicing physical activities
3- Avoid smoking and smokers .
The harms of smoking:
1- Cause cancer of the two lungs
2- Mental disorder
3- Loss of appetite
4- Nervous system disorder and loss of balance.
