Keeping this in consideration, what is the function of the left atrium in the heart?
The left atrium is one of the four chambers of the heart, located on the left posterior side. Its primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart.
Secondly, what is the difference between right and left atrium? The right atrium receives deoxygenated blood from the systemic circulation via the superior and inferior vena cava. On the other hand, oxygenated blood leaving the lungs is carried to the left atrium via the pulmonary veins.
Likewise, people ask, what is the main function of the right atrium?
Medical Definition of Right atrium Right atrium: The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.
Why is the right atrium on the left side?
The right atrium (RA) sits on top of the right ventricle (RV) on the right side of the heart while the left atrium (LA) sits atop the left ventricle (LV) on the left side. The right side of the heart (RA and RV) is responsible for pumping blood to the lungs, where the blood cells pick up fresh oxygen.
