Gas Exchange Adaptations-Cricket Fish Human

Spiracle

• Hole where air enters the cricket gas exchange system

• Filters air containing dust

• The main tube carrying air to the tracheoles

• How the cricket breaths

Trachea

• The smallest tubes in the cricket gas exchange system

• The largest tubes in the cricket gas exchange system

• Contains mucus to trap dust

• The main airway from the spiracle to the tracheoles

Tracheole

• Fine tubes leading from the spiracle to the air sacs

• Fine tubes leading from the trachea to the air sacs

• Fine tubes leading from the trachea to the body cells

• Fine tubes leading from the body cells to the air sacs

Cell Respiration

• Glucose + Carbon Dioxide>Oxygen + Water

• Glucose + Carbon Dioxide>Oxygen + Water + Energy

• Glucose + Oxygen>Carbon Dioxide + Water + Energy

• Glucose + Oxygen>Carbon + Water + Energy

Spiricle Valves are muscles

• True

• False

Cricket Valves

• Muscles that filter dust from the air

• Hairs that filter dust from the air

• Muscles that open and close to prevent water loss

• Found in the air sacs and prevent water loss

Air Sacs

• Store air which can be forced through the crickets gas exchange system by abdominal pumping

• Prevents water loss in a dry, dusty environments by pumping water

• Carries oxygen through the Cricket gas Exchange System

• Is found attached to the trachea

Diffusion in the tracheole endings is improved due to

• 1-2 cell thick tracheoles

• Moisture in the tracheole endings

• The large surface area of the branched tracheoles

• All of these

Chitin Rings

• Provide structural support to the trachea

• Provide structural support to the tracheoles

• Provide structural support to the air sacs

• Provide structural support to the spiracles

Gills

• Contains the filaments where gas exchange takes place

• Contains raker which filter debris from damaging the gills

• Contains a gill arch which holds up the filaments so they float in water

• All of these
