|
Definition
| A condition where a person partly/totally loses their voice due to an inflammation of the vocal cords. |
|
|
Term
|
Definition
| An infection involving a collection of pus in the pleural cavity of the lungs. |
|
|
Term
|
Definition
| A condition where the pleural membranes inside the chest and covering the lungs become infected. Breathing becomes painful due to the fact that these membranes become less slippery than they are in normal form. |
|
|
Term
|
Definition
| A condition where an allergic reaction can cause constriction of the bronchiole muscles, reducing the amount of air to the alveoli and lungs. |
|
|
Term
| Alveolus (Alveoli plural) |
|
Definition
| Small sac in the lung where oxygen and carbon dioxide are exchanged between the air and the blood. |
|

Term
| Why does the respiration system of a bird require a lot more energy to be made? |
|
Definition
| Because they are breathing at a much higher altitude and flying takes up a lot more energy than walking. |
|
|
Term
| What causes a greater capacity for the exchange of oxygen and carbon dioxide? |
|
Definition
|
|
Term
| How has the bird's respiratory system adapted to flight and how is different from mammals? |
|
Definition
Birds have developed "parabronchi" similar to avian alveoli which are open on both sides. In birds, air flows right through air sacs that surround the lungs, into the lungs themselves, back out air sacs and out of the body. This takes place in two breaths (inhale - exhale - inhale - exhale out).
The bird also has a much higher metabolic rate than other mammals which is useful in flight; flying uses a lot more energy than walking or running. Birds take one breath for every six to ten heartbeats. Their respiratory system also is non-tidal. |

|
Term
|
Definition
| Twisted projections that contain blood vessels which filter oxygen into the body. They are the respiratory system for all fish and are very efficient because water contains only 5% dissolved oxygen. In the gills, water flows one way while blood flows the other in a concurrent flow. This method maximises oxygen transfer. Gills cannot be used in air - they lack structural support and would collapse. |

Term
| How has the fishes respiratory system adapted to its environment? |
|
Definition
| The fish has gills which can filter oxygen from the water. It is very efficient because there is only 1/20 (5%) of oxygen in water. |
|
|
Term
|
Definition
| A gas which can be found in feces, which is very good for a plants but dangerous for the environment. |
|
|
Term
| What percentage of water is dissolved oxygen? |

Term
|
Definition
| An oxygen transporting cell of the blood. |
|
|
Term
|
Definition
| The body system that moves blood throughout the body. |
|
|
Term
|
Definition
| The system that brings oxygen into the body and removes carbon dioxide. |
|
|
Term
|
Definition
| The tube that carries air between the throat and the chest. |
|
|
Term
|
Definition
| One of two large tubes that carry air between the trachea and the lungs. |
|
|
Term
|
Definition
| The exchange of oxygen and carbon dioxide between the body and the air. |
|
|
Term
|
Definition
| A sheet of muscle below the chest cavity that functions in breathing. |
|
|
Term
|
Definition
| The volume of air a person breathes in and out in normal relaxed breathing. |
|
|
Term
|
Definition
| The maximum volume of air a person can breathe out after fully breathing in fully. |
|
|
Term
|
Definition
| The number of times per minute that a person breathes in and out. |
|
|
Term
| What CAUSED the bird's respiratory system to evolve? |
|
Definition
| The action of flying uses up so much more oxygen then running or walking as well as the fact that birds fly at higher altitudes where there is less oxygen. |
