1. The Respiratory System By Kaitlyn Browne, Ariel Velazquez Vega, Zara Wimes, and Cordel August

2. What does the Respiratory System do? The Respiratory system takes carbon dioxide in the blood and exchanges it for oxygen. Some animals use it for communication.

3. How does the Respiratory system Function? Respiration happens when oxygen is taken into the body, exchanged in the blood for carbon dioxide, and carbon dioxide is let out of the body.

4. Porifera (Sponges)  Sponges do not have specialized tissue  Sponges siphon in water and filter out nutrients and oxygen in the water  Sponges then excrete waste though the water that moves out of them

5. Mollusca (Mollusks)  Mollusks get oxygen through external openings that connect to a single lung or gills  The gills are called “ctenidia”  The openings are called “pneumostome”

6. ARTHROPODA (INSECTA)  Air enters through openings called spiracles and into the tracheal trunk  A series of internal sacs or tubes (tracheal tubes) diffuse or pump oxygen directly into the body tissue

7. ARTHROPODA (ARACHNIDA)  Oxygen is taken in by book lungs or a tracheal system  Book lungs consist of leaf-like structures stacked like pages  Tracheal systems diffuse air into organs through fluid filled tubes

8. ECHINODERMATA  Gas exchange occurs by diffusion of gasses in the water vascular system  Special thin patches of skin act as gills

9. CHORDATA (Fish)  Water enters through the gills and the gills filter out the oxygen  oxygen is transported to the rest of the body  Gills have a large surface area for maximum oxygen intake

10. CHORDATA (Reptiles)  All reptiles use lungs for respiration  Blood vessels carry oxygen to the organs  Some reptiles can absorb oxygen though the skin

11. CHORDATA (Aves)  The lungs of birds are small and connect to air sacs in the bones  A one-way flow system so old air cannot circulate back into the lungs

12. Interaction  The respiratory system interacts with the circulatory system because the circulatory system carries oxygen to the organs and back to the lungs  The nervous system regulates breathing in the respiratory system

13. Test questions! 1.What is the function of the respiratory system? 2.Describe the respiratory system in a human. (You should know, you are a human!) 3.Give one example of an animal that has lungs.

14. Fun Facts! 1. Without the respiratory system, you would not exist! 2. A bird’s respiratory system is more efficient than a human’s 3. The most common respiratory system on the planet is that of the insects, because they are the most abundant in the animal kingdom 4. Most animals have no lungs and use tubes and diffusion to move air
