The mammalian heart is a complex structure with 4 chambers, the left and right atrium and the left and right ventricle With the atria located above their corresponding ventricles. Blood comes into the heart from the body through the right atrium and then proceeds into the right ventricle. From there, it gets pumped through the pulmonary artery where it gets transported to the lungs. In the lungs, oxygen is added to the blood, and then returned to the left atrium of the heart. The left atrium then empties into the left ventricle. The left ventricle then pumps the blood out the aorta which then directs the blood through the rest of the body where its ready to start the cycle again.

Is the mammalian heart a two sided muscular pump?
Yes- the mammalian heart is a big muscle that has a right and a left side, each with two small chambers: the ventricle and the atrium. Each chamber of the heart pumps at a slightly different time, but each atrioventricular pair pumps closer together than to the other two, leading to to the rhythmic two-pump sound you can hear through your chest.
