Dissection reveals the secrets of nature.

The heart never rests.

Wisdom comes from careful study of the body.

The blood circulates like a river in the body.

Health is the harmony of the humors.

Experiment is the interpreter of nature.

The soul resides in the blood.

Anatomy teaches us the structure of life.

The heart is the prince of organs.

Time heals all wounds, but knowledge prevents them.

The veins and arteries form a continuous circuit.

Nature abhors a vacuum in the body as in the world.

The study of the heart reveals the mystery of life.

Truth in medicine comes from the knife.

The blood is the life force.

Patience and perseverance in dissection yield fruit.
