Chromatin is dna that makes a chromosome and chromosomes are different dna strands in a cell, sister chromatids are identical pieces of dna
The chemicals used for the process
The pressures in the atria and ventricles that would cause the AV valves to open. This is when the pressure in the atria would be greater than the pressure in the ventricles.
<h3>What does pressure in the atria cause?</h3>
The pressure drops below 120 mmHg as the ventricles relax, causing the semilunar valves to close. As the pressure continues to fall, the atrial pressure exceeds that of the ventricles, and the atrioventricular valves open. Meanwhile the blood is being pumped around the body.
With this information, we can conclude that the pressure in the atria would be greater than the pressure in the ventricles.
