The atria don't really have to work at all as most of the blood that flows into them leaks through the atrioventricular valves. The ventricles on the other hand have much farther to pump. The right ventricle has to pump to the lungs and the right ventricle has to pump to the rest of the body so they require a much stronger stroke.

How does atria and ventricle work together?
the atria and ventricle work together as a team - the atria fill with blood, then dump it into the ventricle. The ventricle then squeeze, pumping blood out the heart, while the ventricle are squeezing, the atria refill and gets ready for the next contraction. so when the blood gets pumped ,how does it know which way to go?
What is the difference between atria and atrium?
The term "atria" refers to the plural form of the word "atrium," which is a chamber of the heart that receives blood from the veins. The atria are the upper chambers of the heart, while the ventricles are the lower chambers responsible for pumping blood out of the heart.
What chambers of the heart receives blood from the body?
Right atrium then right ventricle.
When blood flows through the heart what force the blood out of the heart and into the arteries?
The atria Actually, it is the contractions (squeezing) of the ventricles (the lower parts of the heart), not the atria (the upper parts), that do the pumping. That's why the lower part of the heart is larger, and the muscular walls are thicker. The atria receive the blood from the body and pump it down into the ventricles.

Which chamber are receiving chambers of the heart?
The receiving chambers of the heart are the two chambers on the top, the atria. The right atrium takes venous blood from the body, and the left atrium collects blood coming from the lungs where it has been oxygenated. The serious pumping happens in the ventricles, the two chambers below the atria. The right ventricle pumps the blood to the lungs, and the left ventricle pumps the blood out into the body, both pumping at the same time.
Why are the ventricals called the pumping chambers?
The ventricles are called the pumping chambers of the heart because they are responsible for pumping blood out of the heart to the lungs and the rest of the body. The right ventricle pumps deoxygenated blood to the lungs for oxygenation, while the left ventricle pumps oxygenated blood to systemic circulation. Their muscular walls are thicker than those of the atria, enabling them to generate the high pressure needed for effective blood circulation.
What are the parts of the the heart?
2 atria, on the top part, 2 ventricles on the bottom, the left ventricle is the hardest working part of the heart, pumping blood throughout the body
What is the purpose of auricles in the human body?
The purpose of auricles in the human body is to increase the surface area of the atria in the heart, allowing for more efficient blood filling and pumping.
What are the two uppermost and smallest chambers of the heart called?
The two uppermost and smallest chambers of the heart are called the atria. They consist of the left atrium and the right atrium, which receive blood from the body and lungs, respectively. The atria play a crucial role in pumping blood into the larger, lower chambers known as the ventricles.
What does atria pump blood to the body or the lungs?
the atria only pump blood to the ventricles
