Transcript of The Contributions of Andreas Vesalius

My favorite part of anatomy was the circulatory system. I loved learning about how the heart and blood works.
Who is Andreas Vesalius?

Andreas Vesalius was a surgeon in the 1500s that discovered many unknown facts about the human anatomy.
True or False?
I was born into a family of doctors and pharmacists. Both my father and grandfather worked in the medical field.
True! It's no wonder I wound up being a surgeon. My father was even the court apothecary for Charles V of Spain!
Andreas was born in Brussels, Belgium on December 31, 1514.
His mother's name was Isabella Crabbe and his father was Andreas Van Wesel.
Even as a child, Andreas had a great interest in anatomy and the dissection of animals.
True or False?
When I was 16, I stole corpses from the local cemeteries so that I could dissect them.
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steal the bodies I dissected. It wasn't until I had proven myself as both a surgeon and anatomist that I was given the bodies of criminals to dissect instead.
Andreas learned medicine at University of Louvain and the University of Paris.
However, he did not recieve his medical degree until he graduated from the University of Padua in 1537.
Andreas' Personal Life
During his time in college, Andreas was able to really explore the field of anatomy and dissect whole animals. He was intrigued by the study.

What Andreas Discovered
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
My favorite part of anatomy was the circulatory system. I loved learning about how the heart and blood works.
False! Bones were my favorite part of anatomy! I used to search for them in cemeteries and execution places to examine and research!
Galenism
For over a thousand years, Aelius Galen had written all that there was to know about anatomy.
It wasn't until Vesalius wrote a pamphlet on blood letting, a treatment used for various illnesses, that people began to give him recognition for his skills in surgery and anatomy.
After hearing about his work, a Paduan judge began supplying Andreas Vesalius with the bodies of convicted criminals who had been executed. This is when Vesalius started to discover that Galen's theory was all wrong.
When he was just 23 years old, Andreas Vesalius was promoted to the head of the Department of Surgery in Italy.

Galen was a Roman scientist and philospher who made many advancements to unlocking the secrets of the anatomy of the human body.
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
I looked up to Galen because I knew that his version of the human structure was correct.
False! I believed Galen for short period of time because nobody had ever challenged him. Once I found out that there were errors in his research, I wanted to prove him wrong!
However, at the time, Galen was unable to study human cadavers. This led to many incorrect assumptions about the body.
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
True! After dissecting humans and other animals, I discovered that the structures of these species were all incredibly similar. This was my theory of comparative anatomy.
Unlike Galen, Andreas was able to dissect human cadavers because the Church, which had looked down upon that sort of thing, was beginning to lose power.
Soon, Andreas began to realize that alot of the popular theories on anatomy were incorrect.
So, he set forth on a journey to discover the true anatomy of the human body, using the bodies of criminals that had been executed.
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
It was the bad quality of teachings from my college years that persuaded me to further my own research alone.
True! I was extremely dissatisfied with my teachers and the education I received so I became determined to find out the information I needed to learn by myself.
Andreas was able to disprove many popular theories about anatomy. Some of his biggest discoveries, however, focused on the skeletal and circulatory systems.
One of Andreas biggest discoveries about the skeletal system was that of ribs. Contrary to the religious beliefs at the time, Andreas proved that both men and women had an equal number of ribs.
His other major discovery was that of the heart. Andreas disproved Galen's theory that the liver was the center of the circulatory system, not the heart.
The internal structure of humans and other animals is very similar.
SO, WHo is Andreas Vesalius?
The Father of Anatomy!
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
Thanks for watching!

When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
I worked very closely with Charles Darwin and that is why we came up with similar results.
False! Charles Darwin was born 204 years after I died so that would have been impossible.
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
Even though my main interest was in studying the bone structure of humans, my major contribution to science was from my discoveries on the circular and vascular systems.
True! My most popular scientific discovery was when I discovered that nerves were not hollow and that the heart had two chambers and two atria.
True! I was too young to be allowed to dissect anything larger than a cat, so I had to steel the bodies I dissected. It wasn't until I was older at I was allowed to buy the bodies I was dissecting.
When I was 16, I got corpses from the local cemeteries so that I could dissect them.
True or False?
I was considered the "Father of Anatomy" because of his lectures on anatomy.
False! Iw as considered the "Father of Anatomy" because of my 200 drawings and in-depth descriptions in my book
The Fabric of the Human Body
. In fact, scientists today still use my book as a reference, pretty cool, right?
One bit of evidence Darwin used when creating his theory of natural selection was that certain species had almost identical skeletal structures.
Without the information Vesalius collected on the structure and function on the human body, Charles Darwin would not have been able to create his theory of natural selection.
As new discoveries were being made that supported both Vesalius and Darwin's theories, it became evident that Galen's theories were all wrong.
Charles Darwin used the mistakes made by Galen to prove how natural selection worked throughout various species.
Physical evidence that was discovered was that the species who were similar to one another had similar physical features used for similar purposes. For example, Darwin's finches all had slightly different beak shapes, but they were all used for the same purpose.
Andreas Vesalius played a large part in Darwin's discovery of natural selection because of his research done on anatomy.
By dissecting human bodies Vesalius discovered the different parts of our bodies and how each part worked, such as the skeletal structure, muscular system, vascular system, etc.
After examining Andreas Vesalius's work, Charles Darwin created a theory that all living things evolved from one common ancestor that existed billions of years ago.
As time has gone on, scientists have made even more discoveries that support Darwin's theories about natural selection, and none of this would have even been possible without the help of Andreas Vesalius about 300 years ago.
