Homeostasis is the process of maintaining a stable internal environment despite external changes. Our body functions can only maintain their functions efficiently under a narrow range of conditions such as body temperature, water content, carbon dioxide level and blood sugar level. Homeostasis is the process that maintains the stability or constancy of our body's internal environment. To do this, it is necessary for the receptors to identify changes in the external environment, a control center that is usually located in the brain to receive and act on the message from the receptors and effectors to work to return the system to normal. and which is known as negative feedback. It is effective because the change is always reduced to bring the system back to normal. This negative feedback is the most common type of homeostasis control. It is very important that the internal environment of our body is controlled and maintained. The amount of carbon dioxide in our bloodstream must be maintained.Negative FeedbackA negative feedback in the body is where a change in temperature level, blood sugar level, heart rate, or breathing directly leads to an increase or decrease. Negative feedback is responsible for bringing the temperature back to normal. For example, if the body is too hot, sweating cools it. Negative feedback works to maintain body temperature. There are three parts of negative feedback responses and they are called receptor, control center and effectors. Receptors identify changes. Then this message is passed to the control center. Then monitor changes and initiate negative feedback responses when changes are excessive. Then the control center sends signals to an effector to act to help the system… iratory control center located in the brain. It monitors oxygen and CO2 levels in the bloodstream and adapts the breathing rate while maintaining balance and homeostasis in the body. When your body is at rest, your breathing remains steady or constant. It allows you to put the right amount of oxygen into your blood when you inhale and absorb the right amount of CO2 when you exhale. When you do activities that work your muscles or other activities that require extra oxygen, the amount of oxygen in your blood decreases. At the same time the level of carbon dioxide increases. The brain center's respiratory control detects that the levels are off and increases both the heart rate and breathing rate to maintain balance. When you stop performing the activity, the control center slows the return of your heart rate and breathing rate to maintain homeostasis in your blood flow.
