Science Notes Six
Okay, here's some basic digestion and a quick wrap-up of everything else. Sara asked me about the intestines in a comment. For those of you who don't read comments, here it is:
"Hmm. Intestines are part of the alimentary canal. It goes like this:
Mouth --> Pharynx --> Esophagus --> Cardiac Sphincter --> Stomach --> Pyloric Sphincter --> Small Intestine (Duodenum --> Jejunum --> Ileum) --> Ileocaecal Valve --> Large Intestine (Caecum, Colon, Rectum)." Don't trust my spelling here. You also need to know the glands and I lost that page. Somebody should comment for us last-minute studiers. The liver creates bile which helps to break down plant material. Because the rat has no gull bladder (stores bile), the bile is deposited directly into the duodenum. Thus, the rat must eat constantly to use that bile. The stomach moves the food around. The rugae (in the stomach) are muscular ridges that actually stir the food. The undigested food in the stomach is called chyme. And finally, the pancreas deposits insulin into the duodenum. Insulin is a necessary part of the process of breaking down glucose.
*EDIT* Woops, I kinda forgot the quick wrap-up. Here it is...
- Digestion in the Rat: notes are above
- Cell Structure and Theory: notes are below
- Scientific Method: notes are below
- C/NoLO: notes are below
- Genetics: Too easy for notes
- Inorganic Chemisty: you either know it or you don't. I'm not making notes.
