What must the muscle tissue do tto fill the chsmbers in the heart?
The muscle tissue in the heart, known as myocardium, must contract to fill the chambers with blood. When the heart muscles contract during systole, they reduce the volume of the chambers, pushing blood out into the arteries. During diastole, the muscle relaxes, allowing the chambers to expand and fill with blood from the veins. This coordinated contraction and relaxation enable efficient circulation throughout the body.

What are the four phases of cardiac cycle?
The four phases of the cardiac cycle are diastole, isovolumetric contraction, systole, and isovolumetric relaxation. During diastole, the heart muscles relax and the chambers fill with blood. In isovolumetric contraction, the heart muscles contract but the chambers do not change volume. Systole is when the chambers contract and blood is ejected. Finally, isovolumetric relaxation is when the heart relaxes but the chambers do not change volume.
Are the atria are the lower chambers of the heart?
No. The lower chambers of the heart are called the ventricles. The atria are the top chambers of the heart.

The smaller chambers are called atria; the larger chambers are called ventricles. So we refer to these chambers as right and left atrium, and right and left ventricle.
