Yours includes two ventricles and two atria?
heart
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 part of your body has two atria and two ventricles?
I believe this would be your heart because that is the only time ventricles and atria are brought up.
What are the two parts of the hearts?
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.
What are the two heart chambers?
the upper two are atria and the bottom two are ventricles
What difference atria and ventricles fetal pig?
the difference between the ventricles and the atria is that the ventricles are thicker
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 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.
How How many chambers are in the heart?
There are four. Two atria (top) and two ventricles (under the atria).
Where are the atria located What is their function and characteristics?
it is located in the heartThe Atria (plural) or Atrium (singular) are the chambers located in the top of the heart. Below the Atria are the Ventricles.There are two atria in the heart, the left atrium and the right atrium.Atria are located in the heart.
