The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.

How are atria and ventricle differ?
The atria are on the top, and ventricles on the bottom. The atria are smaller, and the ventricles bigger. The atria receive blood coming into the heart, and the ventricles send blood out of the heart. The contraction of the atria end diastole, and the contraction of the ventricles end systole.
Why are atria darker than ventricles?
because it is oxygenated blood
How much blood from the aorta passes into the ventricles before the atria contract?
lots :)
What difference atria and ventricles fetal pig?
the difference between the ventricles and the atria is that the ventricles are thicker
What pumps blood away from heart?
Arteries carry blood away from the heart.
What is difference between auricle and ventricle?
uricles are part of the atria and serve to increase the volume of the atria. The atria that they are a part of serve to direct blood into the ventricles and are not very muscular. The ventricles are far more muscular than the atria and serve to pump blood to either the lungs or the rest of the body ( the right and left ventricles respectively).
Does atria pump blood to the body or lungs?
the atria pump blood only to the ventricles.
What does atria pump blood to the body or the lungs?
the atria only pump blood to the ventricles
What are the functions of the atria and the ventricles of the heart?
Atria is the receiving chamber and it is located at the top while ventricles are the one responsible for pumping blood out of the heart either to oxygenate the blood or to deliver it into our systems and it is located at the bottom part of the heart
When the atria contract the blood is forced into the?
The blood is squeezed into the ventricles.
What is the main function of the right atria left atria?
to force blood to the ventricles
What carry blood to the atria?
Veins carry blood to the atria. In contrast, arteries carry blood away from the ventricles.
How are atria and ventricle differ?
The atria are on the top, and ventricles on the bottom. The atria are smaller, and the ventricles bigger. The atria receive blood coming into the heart, and the ventricles send blood out of the heart. The contraction of the atria end diastole, and the contraction of the ventricles end systole.
Which phase in cardiac cycle is systolic pressure?
Blood flows into the relaxed atria while the ventricles contract. <rephrased> The ventricles contract, carrying blood into the aorta, and blood flows into the relaxed atria.
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.
How would you say the structural difference reflects the relative functions of the two heart chambers?
Assuming you mean the atria and ventricles by "the two heart chambers", the fact that in all species the atria are smaller than the ventricles reflects the fact that the atria receive blood from either the body or the lungs and then pump it into the larger and much stronger ventricles. One-way valves between the atria and ventricles prevent backflow of blood from the ventricles to the atria. The ventricles then pump the blood received from the atria to either the oxygenating organ (i.e. gills or lungs) or the body. The much thicker walls of the ventricles reflect the fact that much greater force is needed to pump the blood throughout the body or to the lungs than is needed to pump the blood from the atria to the ventricles.
What areas of the heart does the antrioventricular valve prevent blood flow from?
The atrioventricular valves prevent the backflow of blood from the ventricles to the atria. They permit the one-directional flow of blood from the atria to the ventricles.
