Slavery in the United States was the legal institution of human chattel enslavement, primarily of native Africans and African Americans, that existed in the United States of America from the beginning of the nation in 1776 until passage of the Thirteenth Amendment in 1865. Slavery had been practiced in British America from early colonial days, and was legal in all thirteen colonies at the time those colonies formed the United States. Under the law, an enslaved person was treated as property and could be bought, sold, or given away. Slavery lasted in about half of U.S. states until 1865. As an economic system, slavery was largely replaced by sharecropping and convict leasing.
It is because Galen based his information about anatomy on what he had found out during dissecting the bodies of animals. This created mistakes on his claims in human anatomy. Some of these anatomical errors were the following:
1. He thought muscles are attached to the bone just like in dogs.
2. He thought that the liver produces blood. He then realized that it flowed around the body, but he claimed that is burned fuel for the muscle.
3. He thought that there are holes through the septum, which allowed the blood to flow from one side to another of the heart.
4. He thought that there are blood vessels in the brain.
5. He thought human’s jaw was made up of two bones just like a dog’s.
6. He made mistakes about the liver’s shape.
