Digestion and Excretion: Absorption, Excretion, and Homeostasis DVD

A great, cost-effective supplement to your school's biology curriculum. This DVD comes complete with printable PDFs of study guides, worksheets, and an annotated script explaining interesting shots along with the location and circumstances involved in capturing them.

It first examines the mechanical and chemical breakdown of food that occurs in the mouth and stomach before looking at digestion and absorption in the small intestine and the enzymes and other chemicals secreted by the liver, gall bladder, and pancreas that aid in the process.

The program then looks at the synthesis of vitamins by bacteria in the large intestine and goes on to explore the complex structures in the kidneys that allow them to filter wastes out of the blood while returning water and nutrients. Chapter search enabled. 30 minutes. 2008
