Respiratory System in Aves Part 1

Respiration: the process by which we get energy from sugar. Breaking down sugars with oxygen.
- Cellular respiration is when sugar is broken down into carbon dioxide and water using oxygen. This chemical reaction releases energy which can be used for contacting muscles (movement).
- Glucose + Oxygen --> Carbon Dioxide + Water
- C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O
- Need a lot of oxygen and need to get rid of a lot of carbon dioxide
Respiration happens in all living cells, it is how life gets the energy to live, plants photosynthesise to produce sugars that can be broken down by respiration.
Metabolic rates
- the amount of chemical reactions that occur in an individual
- include the catabolic cellular respiratory reactions
- birds respire more than mammals
- the increased metabolism results in a slightly elevated body temperature
  - birds have an average of 40 degrees celsius
  - mammals have an average of 38 degrees celsius
- most birds are hardy to the cold
- breaking down: catabolic
- building up: anabolic
