The vena cava is the name given to the two largest veins in the human body. They collect the venous, low-oxygen blood from the body periphery and lead it back to the heart. From there it returns to the lungs, where it is enriched with oxygen before being pumped back into the body’s circulation. In … What is a vena cava?
Definition As part of the “small” or pulmonary circulation, the right ventricle is located downstream of the right atrium (atrium dextrum) and pumps the oxygen-depleted blood into the pulmonary vessels, where it is again saturated with oxygen and then enters the body’s circulation via the left heart. Anatomy The heart lies rotated around its longitudinal … Right ventricle
Histology wall layering The wall layers are the same in all four heart interiors: The innermost layer is the endocardium, consisting of a single-layer epithelium, which is supported by the connective tissue lamina propria. The muscle layer (myocardium) is connected to the outside of this. The outermost layer is the epicardium. Blood supply The heart … Histology wall layering | Right ventricle
Synonym Atrium dextrumThe right atrium is one of the four inner chambers of the heart, which is connected to the large circulation. In it, blood flows in through the vena cava and is passed on to the right ventricle. Anatomy The right atrium is spherical and has the right auricle on the front. The heart … Right atrium
Histology – Wall layers Like the other internal spaces of the heart, the wall of the right atrium consists of three layers: Endocardium:The endocardium forms the innermost layer and consists of a single-layer endothelium. The function of the endocardium is to improve the flow properties of the blood. Myocardium:The myocardium is the actual heart muscle … Histology – Wall layers | Right atrium
