Question

Explain IN DETAIL the negative feedback mechanism that was occurring in your body that lead to taking a breath after having held your breath. Include the stimulus, sensor, afferent path, integrating center, efferent path, effector and response, and briefly explain the role of each as well as the overall impact of the response.

Answer 1

The negative feedback mechanism is the form of regulatory mechanism in which stimulus leads to cause opposite output so as to maintain the ideal level of the system of the process to be regulated. This process takes place in a different series of steps. If someone has a stimulus in which changes occur then you need to have a sensor in which change is detected. Negative feedback mechanisms also involved a homeostatic system like thermoregulation, blood sugar level, and increase blood sugar level. This is the form of reaction that is caused by a decrease in function in response to a stimulus.

The negative feedback mechanism that takes place in the body may lead to taking a breath after holding your breath by the accumulation of carbon dioxide in the cells. This holds blood and lungs which eventually irritate and trigger the impulses of the respiratory tract. Level of carbon dioxide decrease consciousness and autonomous respiration.

1. Stimulus-The negative feedback is the form of regulatory mechanism in which a stimulus leads to cause an opposite output device to maintain the ideal level of regulation.

2. Sensor-Sensor is detected when an ideal level of regulation in the blood is observed. In the negative feedback system, some changes like blood pressure blood sugar are detected by the sensor.

3. The afferent path-Negative feedback mechanism of the afferent pathway is responsible to control the center. The appropriate response as well as the course of action.

4. Integrating Centre is the region of the brain which is also known as the hypothalamus response to stimuli.

5. The efferent pathway consisted of signal that it away from the central nervous system. This is another center that leads to telling to perform some kind of activities like blinking, sensing the temperature.

6. Effector and response are different kinds of optimum levels in which core body temperature is observed and it has blood glucose level . This leads to cause muscle contraction and hormonal release.
