Cardiac Anatomy and Physiology
The heart is about one fist and is located in the chest, right hand boundary at exactly the right sternum and fifth intercostalis apeksnya on the space left on the mid clavicular linea. The upper limit of heart there is a large blood vessels (aorta, pulmonary truncus, etc.); the bottom of the diaphragm; the rear boundary there descendens aorta, esophagus, and columna vertebral; while on each side of the heart is the lung.
Right Atrium
The right atrium is on the right side of the heart and located mostly behind the sternum. Blood enters the right atrium via:
o Vena cava superior to the upper end
o Vena cava inferior at the lower end
o Sinus coronarius (small veins that drain blood from the heart itself)
Auricula dextra is a small sharp protrusion of the atrium, located on the front of the base of the aorta and pulmonary artery. On the left side of the atrium of the right atrioventricular opening hole into the right ventricle.
Right ventricular
Right ventricle is a thick-walled spaces that make up most of the front side of the heart. Valva dextra atrioventricular (tricuspidalis) around the right atrioventricular opening, on the side of the ventricle. This valve, like the other cardiac valves, formed of a thin layer of fibrous tissue covered on each side by the endocardium. Trikuspidalis valve consists of three cusps. Base of each leaf valve attached to the edge of the hole. The free edge of each leaf valve attached to the chordae tendineae (connective tissue thin straps) on a small protrusion of the muscle tissue that comes out of the myocardium and protrude into the ventricles. Pulmonary holes into the pulmonary artery is at the upper end of the ventricle and is surrounded by valva pulmonary valve leaflets consist of three semilunaris.
