Scientific Revolution and the Human Body - MT2 - Part 2 Flashcards
What did Leonardo da Vinci finish/not do? (2)
- He finished few projects
2. Did not organize or publish his scientific work
What did Leonardo learn?
Anatomy as a teenager art apprentice
What was Leonardos main influence in biology and in medicine?
His incorporation of anatomy into art
- killed an dissected animals
What did Vesalius believe in?
Hands on learning compared to reading it in a book
What did Vesalius want to know about organisms?
What they were composed of
What made Vesalius skeptic about Galens work?
He noticed discrepancies
- he knew the difference of what he was seeing vs what Galen was telling him
What did Galen think about the heart?
That it had pores to move the blood
What did Vesalius become aware of Galen?
That he never actually dissected a human body
- this meant that Galen knew less then he did and he didnt have to believe Galen
What could Vesalius do that Galen couldnt?
He could produce a more accurate perspective of the human anatomy
- this is when modern medicine began
What did Leonardo want to understand about humans?
How they were put together
With did the finger of god have to do with?
The human brain
What other things was Leonardo interested in? (2)
- Interested in flight
- thought it was based off of the close study of birds
- wanted to know how wings worked - Interested in geology
- collected fossils
- accepted the reality of fossils when others were skeptics
What did Andreas Vesalius produce?
The first accurate high quality book of human anatomy ever published
- On the Fabric of the Human Body
What did Vesalius become?
The father of modern medicine
How did Vesalius acquire bodies for his dissections?
- Through capital punishment
- the judge would hang prisoners around Vesalius’ teaching schedule so he could use the bodies
- but it was bias to men because women were not hung - Robbed graves
- Cut off limbs from hanging bodies in trees and hid them under his bed
When was his antomony class held and why?
It was held in the winter, so that the bodies rotted more slowly
What was a constant hazard?
Infection
What did they not have? (2)
- Antibiotics
- if you got cut you would most likely develop an infection - Refrigeration
- so he kept the bodies outside so they can decompose more slowly
What was Vesalius’ book 2 main virtues?
- Anatomical correctness
2. High quality illustrations
What did Galen and Vesalius both agree on?
Physiology of the blood
- Vesalius did not propose a circulation of blood
- even though they did not agree on anatomy
What did Vesalius accept of Galen’s?
His philosophy that the human body was perfectly designed by god
What kind of circulation do mammals have?
Double circulation
- systemic and pulmonary
Systemic circuit
Everything outside the lungs
- eg) muscles and organs
Pulmonary circuit
Goes though the lungs
- picks up O2
What was Michael Servetus interested in?
Anatomy
What did Servetus not believe in? (4)
- Salvation of faith
- Infant baptism
- The holy trinity
- Pre-destination
What did Servetus argue?
The in order to understand the human spirit, one must understand the human body
What does Servetus discover?
The pulmonary circuit
- the pulmonary artery is huge = lungs could not possibly consume all that blood
What colour is the blood in the pulmonary artery and in the pulmonary vein?
- Pulmonary artery = dark red
- Pulmonary vein = light red
Why did Servetus think the colours changed in the arteries and in the veins?
Thought that picking up O2 changed the colour and made it lighter
Why did Vesalius and Realdo Colombo stop being friends?
Because Colombo accused Vesalius of anatomical errors
What did Colombo plan on doing after he accused Vesalius of his errors?
He was going to write his own book on anatomy in order to correct Vesalius’ mistakes
- presented a clear statement of the pulmonary circuit
What did Girolamo Fabrici see?
He could see bumps in the veins if arms
What did the bumps in the arm demonstrate for Fabrici?
Showed one way flow of fluid
How did Fabrici show one way flow of fluid?
He squirted was in one direction and it came out the other end and the tried to do the same thing in the other direction but it didnt work
