Parts and Functionsof the Breathing System
Parts and Functions
Trachea
Trachea
• empty tube that serves as passageway of air into the lungs.• Also called as windpipe.• connects the pharynx and larynx to
the lungs.• Belongs to the lower respiratory tract. • Inflammation of the trachea is known
as tracheitis .
Parts and Functions
Trachea
Bronchi
Bronchi
• Singular (Bronchus)• two branching tubes that connect the
trachea to the lungs. • passage of airway in the respiratory
tract that conducts air into the lungs.• No gas exchange takes place in this
part.
Parts and Functions
Trachea
Bronchi
Bronchioles
Bronchioles
• hairlike tubes that connect to the alveoli.• It’s branches no longer contain cartilage or glands in their submucosa.
Parts and Functions
Trachea
Bronchi
Bronchiolesles
Alveoli
Alveoli
• airsacs that allow gas exchange in the lungs. • anatomical structure that has the
form of a hollow cavity.
Parts and Functions
Trachea
Bronchi
Bronchiolesles
Alveoli
Nasal Cavity
Nasal Cavity
• is a large air filled space above and behind the nose in the middle of the face.• conditions the air to be received by the other areas of the respiratory tract.• Each cavity is the continuation of one of the two nostrils.
Parts and Functions
Trachea
Bronchi
Bronchiolesles
Alveoli
Nasal Cavity
Nasal Vestibule
Nasal vestibule
• Nostrils• most anterior part of the nasal cavity.• Enclosed by the cartilages of nose and lined by the same epithelium of the skin.

Guide Questions: • Q1. What does each part of the “Bunch of Grapes”
model represent, in relation to the breathing system? • It represents the passages in the breathing system in
which oxygen flows through it then ended up to a round shape air sac(alveoli) where it filters air and brings out the air again that have been filtered , if you compare the air sac to the bunch of grapes they may look like the same how it function in an easy way on we breathe, the largest stem which holds the other branches is the trachea. Next is the Bronchi, it’s branching stem is the bronchioles then the last part is the alveoli.
Guide Questions: • Q2. How will you describe the pathway of
oxygen in the breathing system? • It is branching and the pathway gets smaller as
the oxygen goes through it. It looks like a bunch of grapes.
• Q3. What will happen if one part of the system fails to carry out its function properly?
• It may cause diseases that may also lead to death if not cured. ( PULMONARY DISEASES )
Inferences• Our breathing system are composed of parts on which air
goes through.• The air we breathe or the oxygen goes through the
nostrils/nose, nasal cavity, going through the windpipe or trachea, then separates into two large branches, called bronchial tubes or bronchi , entering each of the two lungs. It is subdivided many times inside the lungs forming hair like branches/ tubes called bronchioles. The last part is the bubble-like bunch of structures called alveoli or airsacs .
• A bunch of grapes is the best model of the air passage of our breathing system because it shows us detailed information on what it actually looks like inside our body.
• If some parts of the system failed to do its duty, breathing simulation will be malfunctioned.
