1. From Intestine to Rectum Gr C: Explain the function of the two intestine. Gr B: Anayse the adaptations of the ilium (part of small intestine) Gr A:Investigate the multiple roles of the liver. Entrance activity Key terms Explain to your partner the term emulsification and discuss how this happens in the digestive system. Illium Absorption Villus Epithelium Detoxification Transamination Deamination Assimilation Extension activity Arrange these organs in the order they appear in the human alimentary canal. Oesophagus, Anus, Small Intestines, Rectum, Stomach, Duodenum, Large Intestines,

2. Recap activity Small IntestineLarge Intestine Function within the body. Key parts Adaptations Small intestine & large intestine Recap on the information you already know and try to complete the table below. Extension activity Add additional columns onto the table; one for the rectum and one for the anus.

4. Key Word Alert! Villi The lining of the illium is folded into hundreds of thousands of tiny finger like structures called Villi. These project into the liquid digested food and help with absorption. NOTE A singe villi is called a “villus”

5. Teacher explanation

6. Parts of a villus and their function A one cell thick layer on the outer edge of the villus. This provides a small barrier between the inside of the intestine and the neighbouring blood stream. This cell produces mucus which protects the intestine lining against digestion by the body’s enzymes. The groups of cells line the intestines and secrete digestive enzymes (maltase) MATCH UP!!! Learning Activity Glands Goblet cells Epithelium

7. Parts of a villus and their function This tube transports fatty acids and glycerol (lipids) away from the intestines. These microscopic parts of the villus increase the surface area over 20 times, allowing for a much quicker absorption. This part of the villus transports glucose and amino acids away from the intestines. MATCH UP!!! Learning Activity Capillary Microvilli Lacteal

8. Learning Activity Grade A (Linking Scientific concepts) Diffusion and intestines. Using your knowledge of diffusion and the small intestines attempt to explain how nutrients pass through the epithelium of the villi into the blood stream. Note! Some nutrients are absorbed by active transport and not just diffusion! Success Criteria Grace C- Explanation of diffusion and function within intestine. Grade B- Illustrate of how diffusion occurs on the small intestine. Grade A- Following key terms used in explanation- Soluble, concentration, Semi permeable, epithelium.
