Final Reflection

For the entire holiday, i did some research and posted them on this blog.I have learned much more about the digestive system. This blog would be very useful as i can continue looking at it to remind myself about the digestive system. Writing out my learning objectives helps me to work towards them.Overall, the project really helped me learn a lot.Bye!

Week 8 Reflection

For this week, i learned more about the digestive system. I have also learnt a lot within these 8 weeks. I'll will explain it in detail in my final reflection.

The digestive system

When you eat your food, the teeth and saliva in the mouth would break down the starch , the tongue would help mix the food with the saliva. When it reaches the gullet, the muscles in its walls would contract and relax to produce a wave-like movement that pushes the food into the stomach. When it reaches the stomach, the muscles in the wall of the stomach contract and churn the food to mix it with digestive juices. After that it reaches the small intestine where most of the digestion occurs. The undigested food is then moved to the large intestine where the cells lining the large intestine absorb vitamins as well as mineral salts and excess water. The rest are discharged from the body through the anus.

Week 7 reflection

For these 7 weeks , i have learnt a lot more about the digestive system and its function.I hope i can learn more in the last week of the project.

Week 6 reflection

I am learning many things about the digestive system though i did not do much this week as i went for a camp.I should be able to produce more research findings in the next two weeks.

Week 5 reflection

For this week, i have learned about the production of digestive juices . I have also learnt a lot of facts about the digestive system and hope that i can learn more in the next three weeks.I hope that i would learn more than expected from this project.

Production of digestive juices

The salivary glands in the mouth produces saliva which contains an enzyme that digests the starch from food into smaller molecules. The next set of digestive juices are found in the stomach. It produces stomach acid and digestive juices and an enzyme that digests protein. The next set, found in the pancreas, produces a wide array of enzymes that break down the carbohydrate, fat and protein. The last set of digestive juices is found in the liver. It is also known as bile. The bile acid dissolves fats into the watery content of the intestine.
