On Wednesday March 26th, during period two, Beril held the legs wide open while Deborah continued removing the digestive organs from the body of the cat. After finishing with the small intestines, Deborah cut the stomach out and, together with Beril, examined the inside. Deborah then cut out the large intestines and finally finished the dissection process at the rectum.
Questions:
1. What volume of food can a cat's stomach hold when at its maximum capacity?
2. While examining the inside of the stomach, we saw a brown-beige compound in the cat's stomach; was this chyme or digestive juices?
Interesting Facts:
1. After learning about the rugae in the stomach, it was interesting to see how they actually looked and the way the folds were set up in reality.
Reactions:
1. We were uncomfortable putting our hands inside of the cat to remove the deeper internal organs (such as the stomach).
2. We found it strange that the small intestines were made up of a thin layer of smooth muscle. We were expecting for the small intestine to be thicker.
Difficulties:
1. Beril found it difficult to cut the stomach to view the inside because it was very slippery and rubbery.
