The right semilunar valves close and prevent the blood from flowing back into the heart. Then, the oxygenated blood is received by the left atrium from the lungs via the pulmonary veins. Read on to explore more about the structure of the heart. External Structure of Heart One of the very ...
Anatomy of the Human Heart essaysThe heart is a hollow muscular organ. It is located between the lungs approximately in the middle of the chest. It is positioned in the thoracic cavity between the sternum and the vertebrae. It was placed there meticulous
The middle layer, or myocardium, contains the muscle that contracts the heart. The inner layer, or endocardium, lines the heart chambers, according to the British Heart Foundation. Connecting the upper and lower chambers of the heart are the atrioventricular (AV) valves — made up of the ...

This chapter covers the internal and external anatomy of the heart, its positioning within the thorax, and its basic function. Briefly, the heart is a muscular pump, located in the protective thorax, which serves two functions: (1) collect blood from the
There are two atrioventricular valves in the human heart, namely the tricuspid and mitral valves. Both are complex structures whose normal anatomies can vary greatly amongst individuals, and also become modified by disease processes. In this review, we discuss the anatomy, pathology, and issues ...

actually made up of two layers: the outer layer is made of connective tissue that connects to the myocardium, and the innermost layer is made up of endothelial cells that make a nonstick surface for blood flow. The endocardium covers the inner surfaces of the heart, including heart valves. ...
