Anatomy And Physiology Essay

There are over 7 billion people in the world today. Each one of us has the same basic template: a set of arms and legs, one heart, two eyes, two ears, etc., but with infinite variations, no two people are identical. From the findings of anatomy and physiology, the human body consists of six levels of structural complexity. It begins with the microscopic level of atoms and molecules to the largest level, the organism level. Anatomy is the study of the structure and shape of the body and physiology is the study of the functions of the human body. They are two different studies, but anatomy and physiology are closely related and correspond with each other. With such close relations, both sciences are often studied together for an effective learning.

C.), was said to be “the father of anatomy.” One of the most contentious occurrences in history is that Herophilus, along with his colleague, Erasistratus, performed vivisections on living human beings. This controversial event marked the beginning development of human anatomy and became a milestone for future discoveries. He, along with Erasistratus, were the first to analyze the human body which shortly led to the understanding of human organs. Herophilus’ observations consisted of the brain, eye, liver, reproductive organs and the nervous system. He studied the cavities of the brain, which he noted as the center of the nervous system. He would name certain structures based on their shape and many medical terms are constructed with Latin and Greek roots to provide a better exchange of

Harvey was also one to disagree with Galen’s texts because according to Galen, blood is formed in the liver and absorbed by the body and flows through the dividing wall of the heart. However, to counter argue, Harvey examined the heartbeat and found the existence of the pulmonary vein. As a result, it lead him to discover that blood was only flowing one way. William Harvey was then given the title “father of modern physiology.” The studies and observation made by Harvey was one of the most important contributions to the medical field. The discovery of blood circulation by Harvey has pushed the study and knowledge of the human anatomy and physiology
