  2. Tricuspid valve - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_valve

    The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...

  3. Heart valve - Wikipedia

    en.wikipedia.org/wiki/Heart_valve

    The heart valves and the chambers are lined with endocardium. Heart valves separate the atria from the ventricles, or the ventricles from a blood vessel. Heart valves are situated around the fibrous rings of the cardiac skeleton. The valves incorporate flaps called leaflets or cusps, similar to a duckbill valve or flutter valve, which are ...

  4. Right atrioventricular orifice - Wikipedia

    en.wikipedia.org/wiki/Right_atrioventricular_orifice

    The right atrioventricular orifice (right atrioventricular opening) is the large oval aperture of communication between the right atrium and ventricle in the heart.. Situated at the base of the atrium, it measures about 3.8 to 4 cm. in diameter and is surrounded by a fibrous ring, covered by the lining membrane of the heart; it is considerably larger than the corresponding aperture on the left ...

  5. Atrioventricular node - Wikipedia

    en.wikipedia.org/wiki/Atrioventricular_node

    The AV node is labelled 2. The atrioventricular node or AV node electrically connects the heart 's atria and ventricles to coordinate beating in the top of the heart; it is part of the electrical conduction system of the heart. [1] The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, and ...

    en.wikipedia.org/wiki/Cardiac_physiology

    The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation ...

    The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

  8. Koch's triangle - Wikipedia

    en.wikipedia.org/wiki/Koch's_triangle

    Koch's triangle, also known as the triangle of Koch, is named after the German pathologist Walter Koch. [1] It is an anatomical area located at the base of the right atrium, and its boundaries are the coronary sinus orifice, tendon of Todaro, and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve). [2] It ...

  9. Cardiac skeleton - Wikipedia

    en.wikipedia.org/wiki/Cardiac_skeleton

    The atrioventricular rings serve for the attachment of the muscular fibers of the atria and ventricles, and for the attachment of the bicuspid and tricuspid valves. [3] The left atrioventricular ring is closely connected, by its right margin, with the aortic arterial ring; between these and the right atrioventricular ring is a triangular mass ...
