Term
| Difference between respiration and ventilation |
|
Definition
Ventilation: moving air/water
Respiration: Gas exchange |
|
|
Term
| Name 5 different ventilation methods |
|
Definition
Dual pump: (Suction phase, then force phase where mouth closes and pushes it through. Sorta like a heart)
Cilia
Buccal Pump: Swallowing air/water basically
Ram Ventilation: Swims in opposite direction of medium, ramming it through
Lungs: lungs expand, air is sucked in. Lungs contract air pushed out |

Term
| Name 3 ways diffusion drives evolution of respiration |
|
Definition
Surface area (alveolus expands)
Thinner layers of tissues to maximize diffusion (closer blood and median come, more O2 passes)
Moist tissue |

Term
| Challenges with breathing in water vs air |
|
Definition
| Water is harder to move, and has only 1% O2 while air has 20% |
|
|
Term
| What has one way vs tidal ventilation |
|
Definition
Fish: One way
Amphibians, Reptiles, Mammals: Tidal
Birds: One way!!! |
|
|
Term
| Describe the aspiration pump |
|
Definition
Birds breathe by ribs flexing, fused wish bone) with their wings. Elevation/depression of sternum helps drive air
Inhale: air to posterior sacs through bronchi
Exhale: Air hits first part of lungs, displaced from post. sacs
Inhale 2: Air from lungs to anterior sacs
Exhale 2: Air completely exhaled |

Definition
| Little cube like structures in lungs of amphibians/reptile. Not good at gas exchange |
