Introduction
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
History of the Heart
The science and history of the heart can be traced back as far as the fourth century B.C. Greek philosopher, Aristotle, declared the heart to be the most vital organ in the body based on observations of chick embryos. In the second century A.D, similar ideas were later reestablished in a piece written by Galen called On the Usefulness of the Parts of the Body. Galen’s thesis was that the heart was the source of the body’s essential heat and most closely related to the soul. Galen made careful observations of the physical properties of the heart as well. He said “The heart is a hard flesh, not easily injured. In hardness, tension, in general strength, and resistance to injury, the fibers of the heart far surpasses all others, for no other instrument performs such continues, hard work as the heart”(Galen, Volume 1).
Furthermore, Aristotle and Galen’s theories contributed to the Renaissance revival of heart anatomy. This reawakening made it possible for physicians to indicate the basic arrangement of the heart. It became commonly accepted that the heart was divided into four parts: two ventricles (lower chambers that pump blood out) and two auricles (upper chamber that r...

The theories of Hippocrates and Galen are of vital importance to the development of medicine, as they shaped medicine for many centuries to come. Hippocrates was the first to dismiss the notion that magic, spirits, or the Gods could cause or cure disease, reforming the course medicine took. Galen followed in the footsteps of Hippocrates, working relentlessly on human anatomy, endeavoring to fathom how the body functions and what happens when something goes wrong. Without Hippocrates’ belief in diseases being a product of nature revolutionizing medicine, and Galen’s extensive work on the anatomy of the human body, medicine may not have progressed to what it is today.
Throughout history, medicine has existed in many forms. As the technology of cultures advanced, so did the applications of medicine. In the early 1700’s if a person’s liver failed, they would certainly be doomed to death. Who would of thought at that time that a transplant could of occurred, that a liver from a different animal, or another human being could save that person’s life. Though there were theories at that time of organ transplants, the technology nee...
... he also later influenced. Physician William Harvey studied the circulation of blood in 1616 and for the first time he demonstrated the real action of the heart and the course that the blood took through the arteries. Jan Helmont believed that fever was not due to unbalanced fluids, but discovered that it was a reaction to an invading irritating agent. He didn’t use bloodletting and purging but used chemical medicines and improved the sued of mercury. William Shakespeare has been credited as being ahead of his time with regard to his understanding of the medical field. Proof of his excellence lies within his dramas. “Doctors are featured in Shakespeare’s plays more often than any other professionals.”

The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

This was a truly "Ressler" observation, Ressler is the only man I know that could use his mind that is set in genetics and biology and apply it to a spiritual song and come out right. The research that I came up with also triggered a variation of the four chambers of the heart.

Hippocrates was the first Western theorist to write on the topic of vitalism. He assumed that the “...
Some of his anatomical and physiological observations were accurate- for example, he proved that urine was formed in the kidney (as opposed to the bladder which was common belief). His most important discovery was that arteries carry blood although he did not discover circulation” (Galen, BBC).
The concept of anatomy, has improved drastically over the past millenniums, thanks to the brilliant minds of such great philosophers, botanists, mathematicians, doctors, scientists, naturists, chemists and even conquistadors. The overall topic of human circulation can be summed up with the help of nine of these great minds, including Galen, Vesalius, Harvey, Withering, Nafis, Servetus, Columbo, da Vinci and Fabrici.
Chapter 1 of Anatomy & Physiology, The Unity of Form and Function (Eighth Edition) by Saladin is an introduction to the major themes of Anatomy and Physiology. These themes include the history and origin of Anatomy and Physiology, the scientific method, origins and adaptations of humans, structure and functions of the human body and medical terminology.
Dissections were a public event during the time, which also highlights the social importance and engagement with science. Rembrandt’s fascination with medicine is noted in another similar work, The Anatomy Lesson of Dr. Deijman. Both works further the notion that science gave rise to many topics of interest for artist, and that many creators saw science as a stimulating creative field. (Kruger, 2005).
