Digestive System 1

digestive system part 2

Today I have had a lit bit more progress and i think that i am doing quite well. I reaserched the importance of the digestive system and this is what i found out : The food that we eat ; rice, chicken, bread, a piece of fruit or even orange juice, cannot be used by the body in its usual form. Foods and liquids need to be broken down mechanically and chemically into very small particles/molecules. These nutrient molecules are absorbed through the wall of the small intestine and transferred around the body via blood, to nourish cells and organs (from the brain to the immune system),the food is kept in your stomach for 2-3hours before its digested. i also looked up why we need to have a healthy digestive system becasue we are going to need a lot of information to present to the class and we need all the information we can get. However at the moment we are putting together our presentation. draft 5:19:00 PM by Jade Delete

Today in science I reaseached the digestive system and I think itz quite interesting to learn about and i am  keen to learn more.According to right health.com there are 7 organs that make up the  digestive system tract mouth,esophagus,stomach, small intestine ,large intestine,rectum and the anus.it also says  that there are some also some organs that help with digestion  but arent part of the digestive  tract. i  am also reasearching the muscles of the digestive system ; i found out that the stomachs wall is lined with three layers of strong mucles and an adult  stomach can hold up to 1.5 litres of material, i reseached and found that out.
