Zoology Earthworm Practical

Here are the structures you need to know for tomorrow's earthworm practical.  You'll also need to know any functions as well.

External:

• Prostomium
• Clitellum

Internal:

• Aortic arches
• Brain
• Esophagus
• Crop
• Gizzard
• Intestine
• Seminal vesicle
• Seminal receptacle
• Septa

**The practical will involve pins stuck in the earthworm and you will need to identify the structures based on identification/function.  There will be a partial word bank to help with spelling/memory.

Here is a link to the structures:
