11. The respiratory system: anaerobic
Anaerobic respiration
In the absence of oxygen
Quick events
Short time span
Maximal effort
High energy demand
Get glucose from glycogen
Lactic acid build up (poison)
Oxygen debt

12. The respiratory system: anaerobic 2
Oxygen debt:
The consequence of muscles respiring anaerobically during vigorous exercise. You are not breathing, so effectively you are borrowing oxygen, this has to be paid back
Recovery period:
After vigorous exercise we have to breath in extra oxygen. This extra oxygen pays back the debt and helps to break down the build up of lactic acid, turning it in to a waste product to get out of the body
Role of the blood:
The blood does control body temperature, but it also help transport oxygen, glucose and waste products around the body

13. The respiratory system: Recovery period
Expiration of breath
removes carbon dioxide and other waste products from the lungs
Perspiration
This is temperature control, removing excess water in the form of sweat
Excretion
This is in the form of urine and faeces and it gets rid of more waste products

14. Exam Question...
Define Anaerobic Respiration and outline the process of Oxygen Debt and Recovery Period.
(7 marks)
