What is the Difference between top two heart chambers from the bottom?

Answer 1

The difference between the two sides of the heart starts with their different functions. The larger, more-muscular left side has the job of pumping blood all over the body to take oxygen and nutrients to the body's tissues. The smaller, less-powerful right side is responsible for pumping blood only to the lungs. The blood in the left side of the heart has a higher oxygen content because it has just returned from the lungs. Conversely, the blood in the right side of the heart has a lower oxygen content because it just returned from delivering that oxygen to all the tissues of the body. The body is also known for life and life is very important because of DICKS

Answer 2

Think of the heart as having two upper chambers (auricles) and two lower chambers (ventricles). The upper chambers simply serve to pump blood into the lower chambers, and doing less work, are therefore smaller in volume and not as thick as the lower chambers. The lower chambers are the powerhouse of the heart, with the right ventricle pumping the deoxygenated blood back out to the lungs, and the left ventricle pumping the blood through the rest of the body. Its chambers are therefore the thickest in the heart. There is also a thick separation wall between the right and left sides of the heart called the septum.

Answer 3

The upper chambers (atria) have walls that are thinner, and the lower chambers (ventricles) are thicker and have more muscle. They have papillary muscles and trabeculae as well.

papillary muscles contract to tighten the chordae tendinae, which attach to the valves and prevent them from prolapsing (flopping around and letting blood where it's not supposed to be.

fleshy trabeculae of heart irregular bundles and bands of muscle projecting from a great part of the interior walls of the ventricles of the heart. (They look like little ridges all on the inside)

Answer 4

Top two chambers are called auricles or atria. The bottom two chambers are called ventricles. The walls of ventricles are stronger than those of the auricles.

The auricles pump the blood to the ventricles; the ventricles pump the blood to the lungs and aorta.

Answer 5

The Interventricular Septum I think. Not 100% sure on spelling though!
