The procedure is the same when a person sweats. Exercise makes the body temperature go up. Then the body’s way of cooling a person down, the sweat gland (effectors) are set in motion.
When energy is made, exercise continually alters homeostasis by making the body temperature go up. The creation of energy includes, carbon dioxide, heat and water.
In general the heat that is made from aerobic respiration is used to keep the body balanced at 37 c, although too much heat can be created, which then means the body need to get rid of some of this heat or else the body temperature will be too high. To keep homeostasis, the sweating process is triggered easing the heat out of the body.
Homeostasis inside an individual’s body is balanced by negative feedback loops, a bit like a thermostat in the home.
There is a defiant to change .In negative feedback loops, the change instructs a reaction that leads the structure or organ back to the average level. Negative feedback loops consist of a receptor, control centre and effecter.
Receptors can be found in the blood vessels in the body. These control the PH levels and assess the struggle of the flowing blood come through the vessel walls.
When a person exercises there blood pressure goes up, this change is then sensed by the receptors in the blood. A message is then sent to the control centre. (Which is the brain in this situation) then a signal is sent to the effectors to put right the imbalance returning the body to its normal state.
(The effecters in this situation is the blood vessels and brain)
Additionally to sustain homeostasis, when the oxygen goes into the blood from the lungs. The heart rate should also be increased so it can distribute oxygen into the cells. The rise in heart rate speeds up the distribution of oxygen by the capillaries and arteries to the cells that need it.
It also has an impact on the speed of how quickly the blood vessels deliver broken down food components. These are both needed to create energy via aerobic respiration.
The body should release carbon dioxide at the same sort of time as the amount of oxygen that is existing in the blood.
When the cells produce energy, they make carbon dioxide (co2) as waste. The carbon dioxide is then carried through the blood via the veins, returning to the lungs. The carbon dioxide is then exhaled from the body.
To sustain homeostasis, the breathing rate needs to stay at a high level so the excess carbon dioxide that is being produced by the muscle cells through exercise can be ejected from the lungs. When exercise is stopped, the cells will go back to needing normal amounts of energy, which means less carbon dioxide will be produced, and the breathing rate will resume to normal.
Homeostasis may not work the same if a person has an illness or injury. Illnesses such as diabetes can affect the body immensely in sustaining homeostasis.
This assignment shows that when a person exercises homeostasis is challenged and adjustments happen in the body to cope with these changes. The nervous system receives and sends signs about hydration, blood pressure, temperature and other causes. Chemical signals are transported by the endocrine system to regulate body functions. Homeostatic mechanisms react to exercise from changes in respiration, heart rate, carbon dioxide allowance, blood pressure, pulse rate, temperature and the consumption of oxygen.
Through feedback mechanisms, a healthy internal environment can be sustained and can go back to normal promptly when exercise is over.
