Right atrium
- The right atrium is a thin-walled chamber that sits at the top right side of the heart. While it's shape is mostly round, it also has an extension known as the right atrial appendage. Within the walls of the right atrium is the sinus node, an important part of the heart's electrical system that generates the heart beat signal.

Nov 3, 2023 · The aortic semilunar valve is between the left ventricle and the opening of the aorta. It has three semilunar cusps/leaflets: left/left coronary, right/right coronary, and posterior/non-coronary. In clinical practice, the heart valves can be auscultated, usually by using a stethoscope.

Aug 26, 2013 · The right side of the heart receives oxygen-poor blood from body tissues and pumps it to the lungs where it picks up oxygen and gets rid of carbon dioxide. The blood vessels that carry blood to and from the lungs form the pulmonary circuit.

- Summary
The heart is a muscular pump with four chambers: two upper chambers called atria, and two lower chambers called ventricles. These chambers are responsible for the blood's flow through the body.These atria are thin-walled chambers that passively collect blood, while the ventricles are thicker-walled chambers that pump blood to the lungs and body. Th...
The right atrium has a function in both the flow of blood through the heart, as well as in the heart's electrical system. In regards to blood flow, deoxygenated blood from the superior and inferior vena cava and the coronary sinus collect in the right atrium. From there, blood flows across the tricuspid valve into the right ventricle, where it is s...
Various conditions can affect the right atrium. These may be congenital, meaning present from birth, or acquired, meaning developed later in life. They can affect the structure and function of the atrium, resulting in impedance of blood flow out of the right atrium, increased risk of clot formation, stroke, and heart failure.
The right atrium is one of the four chambers of the heart that collects deoxygenated blood and directs it ultimately to the lungs to receive oxygen. Problems with the right atrium can occur from birth or be acquired later in life, usually due to other problems with the heart and lungs. Conditions affecting the right atrium can lead to arrhythmias a...
Jun 11, 2024 · Right coronary artery: This artery supplies blood to the right side of the heart, including the right ventricle, right atrium, and important nodes that control heart rhythm. It branches into smaller arteries like the right posterior descending artery and acute marginal artery.

It travels anteriorly and slightly to the right to reach the atrioventricular groove; it enters the groove and follows it path to reach the cardiac crux, the place where atrioventricular groove meets the interatrial and interventricular grooves at the posterior surface of the heart.
