What difference atria and ventricles fetal pig?
the difference between the ventricles and the atria is that the ventricles are thicker
What part of the blood is atria and ventricles?
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.
What are the four ventricles of the ventricular system?
the different types of ventricles are the left ventricle and the right ventricle.
What two components of the conduction system constitute the only electrical link between the atria and the ventricles?
The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.
When atria relax ventricles do what?
When relaxed, the atria expand, and then the ventricles contract.
Do atria contract before the ventricles?
Yes, atria contracts before 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 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).
What differences between the atria and the ventricles can you feel with your fingers in fetal pig?
The Ventricles are bigger and rougher than the AtriumsThe Ventricles are bigger and rougher than the Atriums.sizeshapewall thickness
Function of atria?
ventricles
What part of the blood is atria and ventricles?
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.
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
Why would the ventricles need to be strong?
The ventricles have to be firmer and more muscular because they have to pump blood much further than the atria.
Are ventricles larger than the atria because they must pump blood farther?
yes
Why are the atria smaller than the ventricles?
Because there is less blood regulating through the lungs and atria. The ventricles have to pump blood through the whole rest of your body.
