Detailed explanation-1: -A typical heart has two upper and two lower chambers. The upper chambers-the right and left atria-receive incoming blood. The lower chambers-the right and left ventricles-pump blood out of your heart.

Detailed explanation-2: -The upper two chambers are called the atria and the lower chambers are called the ventricles.

Detailed explanation-3: -The interatrial septum separates the right atrium from the left atrium; this is marked by a depression in the right atrium – the fossa ovalis.

Detailed explanation-4: -Your heart chambers are four hollow spaces within your heart. 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.

Detailed explanation-5: -Atria-the two upper chambers of the heart-the receiving areas that pool incoming blood.
