✒️ The contraction time of atria and ventricles are different, at first atria perform contraction, after that the blood passed to the respected ventricles.
✒️ Later on the ventricles perform contraction and blood released out from the heart.
✒️ Right ventricle send the impure blood to lungs and left ventricle send the pure blood to entire body.
Answer:
During a single cardiac cycle, the atria and ventricles do not beat simultaneously; the atrial contraction occurs prior to ventricular contraction. This timing delay allows for proper filling of all four chambers of the heart.
