Dietary cholesterol in your body
Graphically represent and explain each of the following steps that show what happens to cholesterol in your body. Include arrows to show the different steps as well as the text shown below to explain each step. Put your picture together in Paint or Photoshop and save as a JPEG. Embed it into The Phizz or wiki
1.Ingest foods high in cholesterol
2.Cholesterol absorbed by the small intestine, and enters the bloodstream
3.Cholesterol absorbed from small intestine into liver
4.Cholesterol combines with triglycerides to form VLDL.
5.VLDL is broken down into LDL
6.LDL exits the liver and enter bloodstream for delivery to peripheral tissues
7.Plaque formed on the inside walls of arteries
8.HDL (already in bloodstream) removes excess cholesterol from arterial walls
9.HDL releases cholesterol back to the liver
10.Bile is released and excess cholesterol is either 1) eliminated in feces or 2) reabsorbed in your bloodstream
Questions: (typed into individual wiki)
1.Explain two diseases that may result from high cholesterol and for each provide a plan to limit the risk of getting the disease:
2.Create a chart below that shows cholesterol values for persons at low, moderate, and high risk for coronary heart disease.
3.Explain two methods of treatment for those that already have high cholesterol or for those that already have major arterial blockage (one of which will be medicine/drugs in which case explain how these work):

The decision to eat…and stop
Your assignment will be to produce a product that diagrams and explains the following steps. Evolution has programmed us to eat as much as we can, whenever we can (ancient humans never knew when they were going to have dinner again. It was best to gorge when they could). Breaking that cycle means thwarting overlapping systems that try to keep you fat. If we are to make a difference in reversing the trend of obesity and continue the trend in fitness, we must understand the major players involved in your appetite. Each step below represents the “key players”
1. I’m hungry: pangs
2. Looks good: senses (time, sight, smell, temperature)
3. Eat: ghrelin
4. Function: purpose/function those foods have
5. Slow down: stretching
6. Stop: cholecystokinin (CCK)
7. Stop!!! PYY and GLP-1
8. Use or store? PPAR’s
9. I’ve had enough: leptin
Create a movie that shows these steps and embed in The Phizz or link to wiki or TeacherTube site
