4. FUNCTIONS OF THE RESPIRATORY SYSTEM
Gas exchange (Oxygen and Carbon
Dioxide)
Breathing and ventilation
Sense of smell

6. BREATHING MECHANISM

Lungs inhales
Overview of the process:
Inhalation (diaphragm and intercostal
muscles)
Exhalation
Diaphragm contracts and pulls
downward
At the same, the
muscles between and
ribs contracts and
pulls downward

EXCHANGE IN
THE ALVEOLI
Alveoli: Tiny air sacs in lungs where oxygen
enters the bloodstream and carbon dioxide
leaves. They're like exchange stations for
breathing, helping us get oxygen in and
remove carbon dioxide out.

9. OXYGENATION OF BLOOD AND
EXCHANGE OF 𝐶𝑂2
9
Oxygenation of blood happens in the
alveoli: oxygen from inhaled air
crosses into the blood while carbon
dioxide moves from the blood into the
alveoli to be exhaled out of the body.
It's a vital exchange ensuring our
blood gets oxygen and removes
waste CO2.

• Asthma
• Chronic Obstructive
Pulmonary Disease
(COPD)
• Pneumonia

•Healthy habits and
care:
“Avoiding smoking
“Regular exercise
“Clean air and environment

12. KEY POINTS
12
1.Function: The respiratory system is vital for breathing and gas exchange.
2.Organs: It comprises the nose, trachea, bronchi, lungs, and alveoli.
3.Gas Exchange: Oxygen from inhaled air enters the bloodstream in the alveoli, while carbon
dioxide exits the body through exhalation.
4.Breathing Mechanism: Involves inhaling oxygen-rich air and exhaling carbon dioxide.
5.Protection: The system filters air, removing debris and pathogens, safeguarding the body.
6.Health Importance: Maintaining respiratory health is crucial for overall well-being, requiring
healthy habits and avoiding harmful practices like smoking.

13. MAINTAINING RESPIRATORY
HEALTH
13
1.Quit Smoking: If you smoke, quitting can drastically improve lung health and reduce the risk
of respiratory diseases.
2.Regular Exercise: Engage in activities that promote lung function, like cardio exercises, which
can strengthen respiratory muscles.
3.Healthy Diet: Consuming a balanced diet rich in fruits, vegetables, and lean proteins supports
lung health.
4.Clean Air: Minimize exposure to air pollutants and allergens. Use air purifiers or ensure
proper ventilation in living spaces.
5.Stay Hydrated: Drinking enough water helps keep mucus membranes in the respiratory
system moist and functioning well.
6.Regular Check-ups: Schedule routine check-ups with healthcare professionals to monitor
respiratory health and address any concerns early on.
