Respiration of Fish, Human, and adult
1. Respiration of Fish, Human, and
Adult Honey-Bee
Comparison of Structure and
Function
By: Katie Raymond
2. Fish Respiration Structure
• Gills- located on the sides of the head
-Made of Gill Filaments
• Gill Filaments- feathery structures that
provide a large surface for gas exchange
- arranged in rows in the gill arches
-each filament has a lamellae
• Lamellae- Discs that contain capillaries

4. Fish Respiration Structure (con’t.)
• Capillaries- blood enters and leaves the gills
through these small blood vessels
• Operculum- a flap that covers and protects
the gills of a bony fish.
– Water enters the mouth carrying dissolved oxygen
– The jaw and operculum move to allow pumping of
incoming water through the gills.

5. Fish Respiration Function
• Water passes over gill filaments
- blood inside capillaries picks up dissolved
oxygen
• Blood in capillaries flows opposite the flow of
water over the filaments.
– This increases the opportunity for absorption.
• The circulatory system then transports the
oxygen to all tissues.
7. Human Respiration Function
• Air enters mouth/nose and travels through
pharynx into trachea, which branch into
bronchioles.
• Air then enters the lungs which absorb oxygen
like a sponge through tiny sacs.
• Alveolar sacs are attached to capillaries and
exchange oxygen.
– This is the location of O2 exchange from the
respiratory system to the circulatory system.
8. Adult Honey-bee Respiration Structure
“Tracheal System”
• Respiratory openings- Spirades
• Divides into branches to reach every organ in the
bee’s body.
• Trachea arms widen to form air sacs that store air.
– They are large, but few in number.
• Small branches and tubes emerging from the sacs
extend as far as the tissues.
• They can accelerate the passage of air into their
bodies by contracting these sacs which speed up
the oxygenation of the tissues.
