Positive and Negative Feedback Loops Prediction of Malfunction


Feedback loops are a crucial part of the functions within our body in the endocrine system and the nervous system. These allow the processes to be regulated properly and function properly. Negative feedback loops stop or slow down a process. They do this when there is enough or more than enough of one type of hormone, or other chemical it may regulate. Positive feedback loops start or increase a process, when there is not enough of a specific chemical or hormone in the body and it is in need of more.

One example of this is with Hyperglycemia, a major cause of complications with diabetes. This happens with all those who have diabetes from time to time, and can be checked upon and known of when you check the blood glucose levels to determine when your levels of glucose are high. This can be reduced through regular exercise and other regular activities. If your glucose levels are high, the feedback loops are not working properly, allowing the body to continue to produce glucose when your body has too much already. This is bad because of complications such as hyperglycemia, and even other types of complications that may be caused due to this. If the feedback loops were working properly, however, the negative feedback loops would have decreased or stopped the process of glucose and insulin production, allowing the body to return to a stage of homeostasis and balance.
Hyperglycemia causes high blood glucose, high levels of sugar in the urine, and increased thirst. These all are signs that your feedback loops are not functioning properly and you should quickly treat it in order to prevent an illness called ketoacidosis from being developed, which causes shortness of breath, nausea, and dry mouth. It can usually be treated through regular exercise, and if it gets worse or is not clearing up, it is best to see a doctor for other treatments and regulation practices.

Nervous System and Endocrine System Prediction of Malfunction


The endocrine system glands and hormones that are released from them influence our entire body. It helps to regulate everyday things in our bodies, including the regulation of our mood, growth and development, tissue function, metabolism, sexual function and reproductive processes. The endocrine system is in charge of the body processes that happen slowly, including cell growth whereas the nervous system controls much quicker processes.

The nervous system is required throughout the entire day, every day. There are three types of neurons, interneurons, motor neurons, and sensory neurons which help the body function properly, be able to breathe, feel pain and other sensations as well as to move.

These two systems work together in order to keep the human body functioning properly. Without them functioning in sync together or properly, many problems can occur within the body. The nervous system controls the endocrine system, and without the endocrine system, the nervous system may not have enough of a specific hormone or chemical needed in order to work properly together.

If the endocrine system has too many or not enough hormones, it can be very harmful to the body. This could also affect the development of nervous system neurons that help the body to move and to feel different sensations important to the body. If your neurons did not transport feelings or act as a bridge, the endocrine system would not receive proteins needed to function. The endocrine system produces hormones, and helps regulate mood, and if for example, the nervous system had stopped functioning properly with the endocrine system, your mood may not be able to be regulated properly. This could lead to major issues, including mood swings and major highs and lows. This is bad for your body because without this mood regulation, your body would not feel homeostasis, or balance.

This is essential to proper function of your body also because your nervous system senses pain. Without this, your body can go through major “pains” without sensing or feeling them, or even the opposite, and not feel and pain, or not receive enough sensations to keep it active and responsive. This is bad because your body is used to feeling sensations and it is very abnormal not to feel anything. Without feeling anything, the neurons are not stimulated, and the nervous system is practically pointless at that point in time.
