no pores in septum, lungs cannot consume blood, blood is different colors

william harvey

on the movement of the heart and blood
questions and problems concerning galenic physiology
- why do artery/veins have different functions but are the same

how are tissues nourished and why respire

where are connections b/w arteries and veins
significance of harveys work
double circuit blood circulation
experimental quantitative bio
mechanical aspects of organisms
blood transfusions - blood loss
mechaniscm vs vitalism
mechanisms: living processes are the consequence of fundamental laws of physics, mechanics and chemistry
vitalism: living processes depend upon a vital force that is not explainable in physical mechanical or chemical terms
rene descartes 1596-1650
crude but influential mechanicism
- physics and engineering but no chemistry
- human beings are mechanisms but possess a soul
- universe is a mechanical system
digestion of food
giovanni borelli 1608-1697 gathered evidence that digestion consists of the mechanical pulverization of food
