Environmental Science T4 The Respiratory System of Turtles

Where are the lungs located in turtles?

• Under the heart

• Below the shell, above the organs.

• Inside the limbs.

• Beneath the shell, on either side of the heart.

Turtle lungs are positioned below the stomach and intestines.

• true

• false

How do turtles ventilate their lungs without a diaphragm?

• By moving their limbs and head

• By using their diaphragm

• By contracting muscles around the lungs

• By expanding their ribcage

How do turtles expand their lungs during inhalation?

• By contracting abdominal muscles.

• By moving their legs outward

• Compressing their ribcage

• Elevating the floor of their mouth

Turtles expel air from their lungs by contracting their limb muscles inward.

• true

• false

How do aquatic turtles differ from terrestrial turtles in their adaptations for breathing?

• Aquatic turtles can only breathe underwater.

• Aquatic turtles have larger lungs

• Terrestrial turtles can breathe through their skin

• Aquatic turtles can use cloacal respiration

The cloaca in turtles serves only as a respiratory organ.

• true

• false

How does the cloaca contribute to respiration in some aquatic turtles?

• By filtering air from water

• By allowing gas exchange with water

• By storing air

• By expanding during exhalation

What role does water pumping play in cloacal respiration?

• It keeps the cloaca dry

• It helps circulate water through the cloaca

• It helps remove carbon dioxide

• It provides oxygen to the lungs

Cloacal respiration allows softshell turtles to stay underwater longer.

• true

• false
