Document Summary

Technical difficulties unsure which information fits under which slides! How fats are absorbed: extra step relative to how chos are absorbed. One of the reasons why you don t want a lot of fat in the diet immediately before you exercise. Is because the absorption into the bloodstream is slow. food outside body and not inside body where it can be used. People who are apprehensive before they exercise, will slow digestion: may need to eat up to 4 hours before they play. Chlylomicrons (protein on outside that hold fat on inside --- transport fat in blood: first one to appear, appear after you consume a meal that contains fat. If they show up in the blood after 6-8 hours of not eating, then you have a problem with how you handle blood fats. taken up by the cells (doesn t happen)

Cells of the pancreas (an organ located in the abdomen that is part of the digestive system) determine the set point for blood glucose (blood sugar). After a meal, glucose levels are elevated and the pancreas detects the change and produces insulin. Insulin and glucose move into the bloodstream where they are transported to different areas of the body. The insulin allows glucose to move from the bloodstream into the muscles and liver where the glucose is stored or used as energy for cellular work.

1. The scenario describes a case in which the pancreas accepts information that the body has absorbed sugar during digestion. Research diseases related to glucose levels and answer each question.

a. Describe what might happen (in relation to homeostasis) if a personâs glucose levels became too high and the pancreas did not secrete enough insulin.

c. List the symptoms of the disease and its treatment options.
