Prepared by:MARICARR D. ALEGRE
RESPIRATION• a life process common to both plants and animals
• There is an exchange of oxygen and carbon dioxide
RESPIRATORY SYSTEM
Phases of Respiration
•External Respiration–Exchange of gases between the atmosphere and the blood
• This involves the lungs
Phases of Respiration
Internal RespirationExchange of gas between the blood and the body tissues
Breathing-a mechanical process that helps get air into and out of the lungs
STAGES
1. INSPIRATION –intake of air
2. EXPIRATION – breathing out of air
PARTS OF THE RESPIRATORY• Nasal cavity
• Larynx• Trachea
• Bronchial tubes• Lungs (bronchioles and
alveoli)
NOSE
NOSE•
Serves as the entrance to your nasal cavity
•Inside the nasal cavities are cilia which
filters the air and trap the any
microorganisms
•A ciliated mucous membrane is also found
in the lining of the nasal cavity
NASAL CAVITY
LARYNX
LARYNX• Also called Adams apple or
vocal cords• Passage way of air we breath
• It is protected by a muscle known as epiglottis
TRACHEA
TRACHEA• Also called as the windpipe• Lined with cilia and fluid that
traps germs and other materials from the air
• Cilia also traps dust and dirt upward away from the lungs
LUNGS
LUNGS• located on each side of the
chest• They are separated by your
heart, blood vessels and your esophagus
• Serves as an organ for breathing
BRONCHIAL TUBES• Branches of
the trachea that is embedded in the lungs
BRONCHIOLES
Small branches of bronchi
ALVEOLI• Also known
as the air sacs
• It is where the exchange of gases happen
