Grasshopper Respiratory System

Grasshopper

Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae. Tracheae open to the outside through small holes called spiracles. In the grasshopper, the first and third segments of the thorax have a spiracle on each side.

Hydra

Respiratory System

Hydra

Hydra hasn't organ for breathing. Hydra uses the skin of the outer cell group (Epidermis) The epidermis, which surrounds the hydra, is able to take in the oxygen from the water. The waste, carbon dioxide, is then released in the same way through the epidermis. Having a thin epidermis and lacking a respiratory system allows hydras and other organisms in this phylum to breathe using passive diffussion.

Reptiles

Respiratory System

Most reptiles breathe as humans do: They inhale oxygen through their nostrils or mouths.However, aquatic turtles and some snakes also can extract small amounts of oxygen from water.

Reptiles

Turtle

Tortoise

Respiratory System

- When tortoise breathe air, they need to come to the surface to breathe oxygen. But they have adaptations that allow them to stay underwater for long periods of time. They even have an adaptation to absorb small amounts of oxygen without breathing. Pond turtles can survive without breathing for more than four months.

- Tortoise pull oxygen from the water via the skin on their necks and cloaca - the chamber through which feces and eggs pass.

Snake

Respiratory System

- Snakes usually surface to replenish their oxygen stores, they can absorb some oxygen from the water via their skin.

- Larger right lung (1/2 length of body) and small non functioning left lung.
