After understanding structure of muscle we know that is highly complex contractile system. It is removal of blood from the body of a slaughtered animal. Homeostasis comes into play as soon as the process of exsanguination begins. Homeostasis is a system of checks and balances which through these efforts tries to maintain a physiological balance of internal environment. It executes the efforts to support the desire of a living being to live.
Homeostatic system is regulated by nervous systems.
These systems trigger mechanisms of checks and balances in an attempt to live. Temperature of carcass rises due to failure of temperature control mechanism. Myoglobin stores little oxygen which is sufficient for short period as a result stored oxygen is depleted. The above sets in anaerobic metabolism leading to production of lactic acid. The energy so produced is less and is only sufficient to maintain structural integrity and temperature.
