Digestive System | Nutrition | Compulsory Tasks

 

LI. To explain what the main organs in the digestive system do. 

This week for inquiry we had to finish the compulsory tasks. Mojtaba, Matthew, Lukah, and Victoria did this activity. They got two credits for this. We had to write the main organs in the circle and the out it the more unrelated the organs are. We colored the circle in our favourite colors. Mojtabas favourite color is red, Matthews favourite color is cyan, Victorias favourite color is baige and Lukahs favourite green. Then we had to write a description.

LI. To describe the structures and perspective functions in the human digestive system. 

This week for inquiry we had to finish the compulsory tasks. I drew the digestive system and tried my best. I got two credits for The Quizzers which is my group. We are now on to sixteen credits. My group is trying to get twenty five credits so each one of us can buy one question. 

LI. To define digestion. 

This week for Inquiry we had to finish the compulsory tasks. Victoria and I did this presentation. I used my research skills in order to find some of the information. We explained two of the related organs that help the digestive system such as- Liver, and Kidney. The kidneys wash the blood and take all the waste products from the blood into the gallbladder which gets stored then released.

Earthworm digestive system

The earthworm digestive system is a complex cycle, the cycle starts with- prostomium, pharynx, esophagus, crop, gizzard, intestine, and anus. A digestive system is a group of organs or body parts helping something or someone digest the food they have been given or eating.

Earthworms swallow food through the mouth. A flap, called the prostomium under the mouth holds the worm’s food in.

The food travels down to the pharynx. It gets lubricated in mucous, which makes it slimy and slick.

The slimy food travels down the esophagus. It gets mixed with calcium carbonate which neutralizes the acid.

The crop is a storage zone. The slicky food gets mixed together again.

The gizzard churns and mixes the food. The gizzard churns the food for the earthworms because they have no teeth to grind the food themselves; in the food there is very tiny rocks and sand grains that helps grind the food, also a chemical digestion starts in the gizzard.

The paste then travels to the intestine. The volume of the earthworm body is made up of the intestine, the food passes through the earthworm and intestine, while it travels through kind of bacteria starts to break food down, so the blood vessels that line the intestine can take in the nutrients into parts of the body.

When all the waste travels to the end of the intestine the anus will take all the waste out so it can be a healthy earthworm. It will release its urine, the digestive system’s style is a complex cycle or system.

Prostomium covers mouth, food in pharynx, into esophagus, crop stores food, gizzard churns food, travels intestine, exits anus.

This process or cycle is like the human digestive system because humans have acid in the stomach that breaks down the food or chunks we have not chewed.

LI. To compare digestion in humans and other living organisms. 

This week for inquiry we had to finish the compulsory tasks. I wrote a eighteen sentence explanation because we did this for writing. We did the earthworm digestive system. I think the earthworm digestive system is complex. I got one credit for my group, we now have sixteen credits in total.
