What is a dissected frog?

Do you dissect frogs in biology?

Why do frogs dissect?
Frogs are often used in dissection when demonstrating the organ systems of a complex organism. The presence and position of the organs found in a frog are similar enough to a person to be able to provide insights into the internal workings of the human body.
Does frog have teeth?

What do people do to disect frogs?
Frog Internal Anatomy – Dissection Guide Lay the frog on its back, spread out its limbs, and pin them to the tray.
