Human Respiratory System

Henny Puspita Dewi, S.Pd

Why do we need oxygen to survive?

Important component of the respiration reaction that occurs in all cells.

Our Respiratory systemNose WindpipeAir tubesLungs Air sacs

Further InformationNose, when we breathe in, air rushes into our

body through our nose and air will cleaned, warmed, and moistened.

Windpipe, the air then moves down our windpipe.

Air tubes, the windpipe branches to the left and right into smaller air tubes.

Lungs, each of this air tubes leads to one of our lungs and branch with air sacs.

Air sacs, for gas exchange.

Wonderful LungsLungs is the most important organ in our

respiratory system.Almost the process of the

gas exchange occur in ourlungs.

Breathe in and Breathe outBreathe in

Our ribcage moves

outwards and upwards.

This causes the space in

our chest to become

bigger and air rich in

oxygen is drawn into

our lungs.

Breathe out

Our ribcage moves

inwards and

downwards. This causes

the space in our chest

to become smaller and

air rich in

carbondioxide is forced

out of our lungs.

What happen when our respiratory system fails to work properly?Micro-organism and pollutantsMay cause some diseases like:

AsthmaBronchitisEmphysemaLung cancerTuberculosis

Asthma: caused by an allergy – breathlessness or gasping for air may occur during an asthma attack.

Bronchitis – an inflammation of the windpipe and the two main air tubes that lead to the lungs.

Emphysema – Enlargement of air sacs in the lungs and caused by smoking.

Lung Cancer – when cells in the lungs grow and multiply without control and abnormally forming a tumour

Tuberculosis ???

Infectious and inflammatory lungs disease cause by bacteria.It spread when an infacted person sneezes or cough into the air and infected air is inhaled by others.

How to love our pink and healthy lungs?Take more exerciseNot to smokeTake more air deeply

Don’t forget to love and keep your lungs

Thanks for your kindly attention
