Homeostasis - Assignment Examplethe brain receives signals about this change in the energy demand, a negative feedback mechanism works to regulate it back to regular levels (Kelliher & Media, 2011). Energy human beings requires oxygen so the more you run, the more energy is used which causes the ventilation rate to increase so that there is enough energy for the cells. This increased demand for oxygen and energy means that the negative feedback gyrate will increase the blood pressure and breathing rate so that the blood is oxygenated quickly and is delivered to the contract muscle tissue (Sherwood, 2008).During exercise, aerobic oxidation of glucose takes place initially which means that the rate of oxygen economic consumption is enough to meet the oxygen and energy demands. However as we continue to run, anaerobic oxidation starts which causes the breathing rate to increase further and this causes an oxygen deficit and lactic acid build up (Sherwood, 2008). at one time you stop running and rest, your bodys negative feedback loop works to regain stability and dispatch the Lactic Acid by oxidizing it. This is known as post exercise oxygen consumption which would explicate why Farah was still breathing heavily during the interview. It was because the negative feedback loop was working to ensure an increased do of oxygen uptake to remove the oxygen deficit and oxidize the Lactic Acid (Sherwood,
