Yes
Atria are a part of the heart and so consist of cardiac muscle cells, which are different from any other muscle cells found in the body. Atria also have specialized cardiac tissue called the SA node and AV node, which are involved in conducting impulses to different regions of the heart.
The are extentions of the Atria.
yes because during atria systole, the heart muscle tissue contracts.
The left and right atrium (or atria).
The muscle tissue on one side contracts while the other relaxes, controlled by electrical impulses to the heart muscle.
interatrial (between the atria) interventricular (between the ventricles) atrio-ventricular (between the atria and the ventricles) So, each chamber is separated by a septum
smooth muscle's, they connect on the other layer and inner liner of that system
Cardiac Muscle or myocardium are the muscle that make up the heart that contract and relax to pump blood.
The chordae tendinae and their attachments to the papillary muscles prevent the AV valves from collapsing backwards into the atria.
The are extentions of the Atria.
the atria
The atria are a part of your heart which is in the circulatory system
The Atria and Atrium
contraction of the atria and ventricle of the heart, causes beating of heart.
salamanders have a heart with one ventricle and two atria
yes because during atria systole, the heart muscle tissue contracts.
The ventricles are the lower heart chambers that contract to pump blood. The upper chambers, atria, also contract, but to a lesser degree.
Atria is the plural for of atrium. Not the other way around.
