History of Anatomy and Physiology
Imhotep, 2650-2600 BC: recorded some of the earliest information on surgery
Aristotle, 384-322 BC: founder of comparative anatomy
Herophilos, 335-280 BC: “The First Anatomist,” described the diagnostic value of the pulse
Erasistratus, 304-250 BC: contributed to the understanding of the anatomy of the brain, and noted the difference between motor and sensory nerves

History of Anatomy and Physiology
Galen, year 129-200 AD: “First Great Anatomist,” his writings remained unchallenged for 1,500 years. Conformed his anatomic findings to theological principles
Andreas Vesalius, 1514-1564: “Father of Modern Anatomy,” corrected Galen’s mistakes. Dissected human cadavers.
Ambroise Pare, 1510-1590: “Greatest Surgeon of the 16th century,” first to ligate vessels to control bleeding after amputations .

Organization of the Human Body
The levels of organization progress from the least complex (chemical level) to the most complex (organism level)
Atoms and molecules are referred to as the chemical level

Organization of the Human Body
Cells are the smallest living units of structure and function in our body.
Tissues are an organization of many similar cells .
Organs are an organization of several different kinds of tissues.
![Page 10: ST110 CONCORDE CAREER COLLEGE, PORTLAND Organization of the Human Body.](https://reader036.fdocuments.in/reader036/viewer/2022062320/56649ca65503460f94967b59/html5/thumbnails/10.jpg)
Organization of the Human Body
Systems are varying numbers and kinds of organs working together to perform complex functions.
The body is a unified and complex assembly of interactive components.
