The Human Heart
The human heart is an organ that pumps blood through the circulatory system into the human body. The human heart is a complex organ which has special parts, a complicated way of working and further requires multiple tasks to be done to keep the heart healthy. In, order for the human heart to work properly, it uses specific parts that allow it to run. With these specific parts, the human heart works in a particular way further explain. When certain defects are formed in the heart, many diseases can occur further explained. To help fix the disease in the heart there are many surgeries that are done. In some surgeries, machines are inserted into the heart which allows the heart to behave better than it did without the machine. …show more content…

First, the human heart is covered in Membrane (protective film) which protects the heart. Likewise, the heart divided into two parts by a thick muscle called the septum and on each side of the two parts, there is two atrium which is hollow chambers. In addition, the right atrium is filled with oxygen-poor blood and the left atrium is filled with oxygen-rich blood. Again, the lower chambers of the heart are called the ventricles. In addition, the valves in the human heart are billowing flaps attached to the four chambers of the heart. Thin cords hold the valve between the atrium and ventricle, during every heartbeat, the head strings keep the valve from turning inside out. Still, thin cords hold the valve between the atrium and ventricle, during every heartbeat, the head strings keep the valve from turning inside out., the pulmonary artery is the artery (thick muscle and elastic layers that allow blood to pass through.) That protects the heart. To understand the human heart’s various topics presented in this report the reader must be able to understand the parts of the heart because it helps give basic knowledge to the readers when reading the

  • The First Artificial Heart Transplant

    The development of the artificial heart began in the early 1950’s. The initial prototype, developed in 1970’s by the artificial developmental staff at the University of Utah, allowed 50 hours of sustained life in a sheep. Although this was called a success, the implantation of the artificial heart left the sheep in a weakened state. It wasn’t until late 1970’s and the early 1980’s where the improvement of the artificial heart actually received attention as a possible alternative to a heart transplant. The remodeled product of the early 1970’s did more than just the 50 hours of sustained life; it enabled the cow to live longer and to live a relatively normal life, with the exception of a machine attached to the animal.

    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).

    Cardiovascular disease is currently the leading cause of death in the United States. It is responsible for one in four deaths every year, about 600,000 mortalities. This disease affects men and women, as well as every ethnic group. Coronary artery disease is the most common cardiovascular disease, representing approximately 400,000 deaths per year of the aforementioned 600,000 total deaths from cardiovascular diseases as a whole. In 2010 alone, coronary artery disease cost the United States $108.9 billion for health care services, medication, and lost productivity. These chilling statistics, published every year by the American Medical Association, demonstrate the immediate need for new and innovative ways to prevent, detect, and treat coronary heart disease. This paper will explore the molecular biology behind the disease while explaining the current treatments and prevention that are available today, why they work and what can be done to improve them.

    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...
