Frog Dissection

In Class we dissected a frog. As we dissected, a foul odor,(however not as bad as the worms)came out of the frog. We had to cut apart muscle and I was forced to break the frogs arms so we could pin it down. After that, the inside was very interesting.

Our frog was a female, as we could tell from the eggs. the eggs were greyish blackish and were slimy. We had to remove the eggs to see the other essential organs. At first glimpse, you would see the 3 lobe liver. Then you would see the stomach. While we were dissecting, our group found some spaghetti like strands in the frog. Those are fat bodies, which are basically just fat. We had to remove that to.

The frogs stomach was a organ that our group cut open. Mrs. Rousseau told us that sometimes the stomach would contain pieces of undigested food, such as flies. Unfortunately, our frog was dead hungry.

I wonder why there were so many eggs in the body. I also wonder how many of them die before birth. I also want to know what is the significence of the 3 lobe liver. What is the difference between the human and frog body, based on internal features. Why is the frogs skin green/brown. There are so many questions, and a lot of them may be answered.

The Circulatory System

Hydrochloric acid

Today, we experimented with hydrochloric acid. It is something in your stomach that is very dangerous and can burn you. We put egg raw in it. the egg raw hasn't changed yet, but tomorrow it might. I was forced to take off the caps. I was scared that the hydrochloric acid would go on my skin.

Halloween

Wats up? Halloween is over and feasting is on. Let's all have a sugar rush.

Getting a dog

Getting a dog! Labrador Retriever!

Chicken

Today, we dissected a chicken wing. We dug in a lot to see the nerve, muscle, bone, cartilage and other things. I truly felt disgusted, but I'll live with it. However, at the same time it was cool. That was what we did.

lab post

In class we mixed iodine with water. It made a apple juice like color. However the bag containing the white stuff (I forgot what it was called) didn't affect it at all. Maybe it was the plastic bag.......

Peace!!!!
