Much like the wide, open architectural atrium that functions as receiving sites for incoming guests, the cardiac atrium is a pair of chambers situated at the upper part of the heart that receives systemic and pulmonary blood. The right atrium receives deoxygenated blood from the systemic circulation via the superior and inferior vena cava.
The right atrium is one of the heart's upper chambers that plays a role in blood circulation. It collects deoxygenated blood and directs it on a pathway to get oxygen from the lungs. Problems with the right atrium can occur from birth or due to problems with the heart valves or muscles.
The right atrium is one of the four chambers of the heart. The heart is comprised of two atria and two ventricles. Blood enters the heart through the two atria and exits through the two...
There are two atria (upper chambers) called your right atrium and left atrium. In addition, there are two ventricles (lower chambers) called your right ventricle and left ventricle. Each chamber plays an important role in your heart’s functioning.
Right atrial enlargement means your heart has an abnormally large right atrium. This upper chamber of your heart receives oxygen-poor blood from your body. High blood pressure and blood volume cause right atrial enlargement.
The atrium (Latin: Ätrium, lit. 'entry hall'; pl.: atria) is one of the two upper chambers in the heart that receives blood from the circulatory system. The blood in the atria is pumped into the heart ventricles through the atrioventricular mitral and tricuspid heart valves.
The right atrium sits anterior, inferior and to the right of the left atrium. It forms a portion of the upper anterior (sternocostal) surface and a portion of the right pulmonary surface of the heart. The right atrium has thin muscular walls as it functions under low pressure.
The right atrium is one of the two atria of the heart, which function as receiving chambers for blood entering the heart. It is located to the right of the left atrium and superior to the much larger and more muscular right ventricle.
In the anatomical position, the right atrium forms the right border of the heart. Extending from the antero-medial portion of the chamber is the right auricle (right atrial appendage) – a muscular pouch that acts to increase the capacity of the atrium.
The right atrium is located in the upper portion of right side of heart consisting of the sinus venosus and the right atrial appendage; contains the sinoatrial node.
