WORMS!

Today, we finished the internal dissection of our worm! It was sooo fun!
I learned so many different things I hadn't learned before, especially when it came to the the digestive and circulatory system. When I first saw the worm, it looked like a straw to me, long and thin. It was hard to think that such a small organism could have such complex body systems.
Though the preservative didn't smell too good, it was really cool to see what the inside of a worm actually looked like, along with learning many new facts. What I thought was the coolest was if you poked the intestines or cut through, you could clearly see the dark, fertile dirt, which was the worm's main source of food. Next, I also didn't know that a worm's brain was so tiny!
In addition, if you kind of lifted the whole digestive system in a way, you could see the ventral nerve cord running through the bottom; a white line and bouncy in a way.

All in all, the new vocabulary I learned through the lab were: setae
                                                                                           anterior
                                                                                           posterior
                                                                                           dorsal
                                                                                           ventral
                                                                                           clitellum
While observing the exterior and interior of the worm, I saw and can now tell the difference between the dorsal/ventral, the anterior/posterior, and all the organs: mouth; pharynx; hearts; esophagus; crop; gizzard; intestines; clitellum; anus; ventral nerve cord; and blood vessels.

Can't wait for the frog! :)
