Anatomy is one of the oldest branches of medicine, with historical records dating back at least as far as the third century BC . Cardiac anatomy has been a continually explored topic throughout this time, and there are still publications on new facets of cardiac anatomy being researched and reported today. One of the fundamental tenets of the study of anatomy has been the description of the structure based on the universal orientation, otherwise termed the anatomic position (Fig. 2.1 ). The anatomic position depicts the subject facing the observer and is then divided into three orthogonal planes. Each plane divides the body or individual structure within the body (such as the heart) into two portions. Thus, using all three planes, each portion
Inside the heart the four chambers were clearly defined and hollow. The wall on the left side of the heart was much thicker and firmer than the wall on the right side. The wall on the right side was very thin. The valves appeared stringy, stretchy and very long.

Most heart diagrams show the left atrium and ventricle on the right side of the diagram. Imagine the heart in the body of a person facing you. The left side of their heart is on their left, but since you are facing them, it is on your right.
This article will explore your heart's anatomy. We'll describe its exterior, including the arteries and veins that supply blood to the muscle. We'll also describe the organ's interior, including the chambers, valves, and blood flow. Lastly, you'll learn how its electrical system helps ensure its proper function.
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
Throughout the years the general population has become detached from each other, thus creating a civic engagement gap that has been seen to affect the youth over other age groups. In Gen.com:Youth, Civic Engagement, and the New Information Environment, Michael X. Delli Carpini Professor of Communication analyzes the current decline in civic engagement among youth. Carpini examines the possible origins of this growing problem and additionally provides the audience with an innovative yet unrealistic solution.
Our demonstration’s final results is the exhibition of a heart model with its anatomy labeled and painted red tubes inserted showing the circulation of blood along with the research to achieve our purpose for this demonstration. The purpose is to explain info on the heart, how the heart functions, what vital role it plays in our body, and clear any misconceptions/answer common questions on the heart. In the demonstration, the first explanation will be to clarify info on the heart using the model. The research for that is the heart is a muscular organ located little to the left of the middle of the chest and it’s about the size of a normal hand fist. The heart has four chambers: the right atrium, right ventricle, the left atrium, and the left
The aim of this report is to provide an overview of chronic heart failure, examining signs symptoms and treatment related to the case study, medical history. The anatomy and physiology of the heart will be discussed, and the pathophysiology of chronic heart failure.
The heart is a double pump that circulates blood to all parts of the body. The three structures that take blood from the heart to the cells back to the heart are arteries, veins, and capillaries. Blood carries oxygen and nutrients to the cells back to the heart. The lymph system returns excess fluids from the tissue to the general circulation and manufactures lymphocytes. Surrounding the heart is a double layer of fibrous tissue called the pericardium.
Hemodynamics is the study of blood flow and circulation throughout the body. A muscle known as the heart is a major organ that circulates blood through the human body by veins and arteries known as the circulatory system. During the pumping action it carries deoxygenated blood through the veins to the lungs where oxygenation takes place and is then circulated through the arteries back to the heart.
The heart is one of the most important organs in the entire human body. It is really nothing more than a pump, composed of muscle which pumps blood throughout the body, beating approximately 72 times per minute of our lives. The heart pumps the blood, which carries all the vital materials which help our bodies function and removes the waste products that we do not need. It is so essential to our survival that any malfunction or congenital or acquired defect can lead to major complications and possibly death. Ventricular Septal Defect (VSD) is a congenital heart disease that affects the membranous part of the interventricular septum. A defect in the interventricular septum allows communication between the systemic and pulmonary circulations. As a result, flow moves from a region of high pressure to a region of low pressure. In other words, blood flows from the left ventricle to the right ventricle, hence the name left-to-right shunt. There are various degrees of severity for this disease by having either a small or large shunt. Patients with a small shunt are asymptomatic and their life prognosis is very optimistic compared to those with a large shunt. In the latter case, a medium to large shunt increases pulmonary blood flow, which causes pulmonary disease and may cause cardiac failure. This congenital heart disease is the most common of form of congenital cardiovascular anomalies. Other forms of congenital heart disease (CHD) include atrial septal defect (ASD), pulmonary
The study of the heart and circulatory system, together referred to as the cardiovascular system, has been a topic of interest for many centuries. As one of the most complex and sophisticated systems in the human body, the journey towards our current understanding of it’s form and function has been a long one. Even cardiology, the study of the heart and circulatory system is still relatively in its infancy as a medical specialty.

Into the Heart: One Man's Pursuit of Love and Knowledge Among the Yanomama. By Kenneth Good with David Chanoff is Anthropologist Kenneth Good’s attempt to disprove Napoleon Chignon critics who argued that ecological factors, not genetics, were responsible for their horrible temperament. Good goes to the rain forests of the Amazon to live and study the diet among the Yanomami. Good began a relationship with his village that continued not for the anticipated 15 months but for 11 years. He found more than one of the few remaining peoples untouched by modern civilization. In truth, there are a lot of people home in the dense rain forest nearly 10,000 Yanomama to be exact.
