Discuss the role of negative feedback in living organisms and how it benefits these living organisms? (25 marks) Negative feedback is the process by which changes occur to bring an organism’s internal environment back to the normal level. One example of negative feedback in a living organism is the ways humans regulate their blood glucose levels. I will firstly discuss the processes that occur as a result of blood glucose levels being too low. When blood glucose levels are too low the pancreas

Week 3 Overview | | | | From the long tube of the gastrointestinal system and the lungs of the respiratory system last week‚ we move on to that very sensitive system of the body—the skin‚ and to that miraculous system of the body—the heart and the related circulatory system. You will add words related to the integumentary system and the cardiovascular system to your vocabulary of medical terms. Start this week by reading the online lectures. Use the textbook to learn medical terms related

Some negative effects of this rapid weight loss that this article discusses are that it can lead to acute cardiovascular dysfunctions‚ immunosuppression‚ lowered bone density‚ impaired thermoregulation‚ impaired cognitive function‚ negative mood state‚ hormonal unbalance‚ temporary growth impairment‚ poor nutritional status‚ increased injury risk‚ and increased risk of developing eating disorders.
