Imagine you are a physician preparing a talk detailing the impact of obesity on the respiratory and digestive systems. Prepare a written paper of at least 1000 words that examines the following bullet points:
A. What regulatory mechanisms (both physical and chemical) help maintain homeostasis in the respiratory and digestive systems?
B. How does excess weight cause imbalances that result in medical conditions?
C. What are the physiological impacts of the three different types of bariatric surgeries (gastric band, gastric sleeve, and gastrointestinal bypass)?
