Rat Dissection Lab

Rat Dissection

Today in Biology we did our last dissection of the year! The Rat Dissection! At first I was a  bit nervous to do this lab, but soon once we got closer to the organs, it became really interesting!

Here is a nice picture of what our Rat looked like before we started to learn about it's organs.

Here is a nice picture of what our Rat looked liked, and as you can see it has a yellow/white color, and is about 23 cm long.

This is the bottom of part if the rat which shows a general picture of what it's hands, feet ,and belly looks like.

This is a close-up of the mouth which has pretty big teeth, it's nose which is surrounded by whiskers, and it's front arms which assist it in eating and walking.

Here is the bottom half of the rat and from this photo, we can see that this rat is a Male because it has Testis. Also this picture shows a close-up of it's hind legs which help it make quick get-aways when in danger.

Once we started the dissecting, I couldn't help but notice how this rat innards were so similar to the Human's innards.

To make things easier, here are all the organs found in the rat all labelled and separated on nice clean paper towel.
