Question

Match the following cardiac cycle events in the correct order like from First to last Intraventricular pressure increases to more than the pressure in the aorta Blood flows from the ventricles to arteries Volume of ventricles decreases Ventricles contract Intraventricular pressure decreases to less than the pressure in the atria Atrioventricular valves open Ventricles relax Volume of ventricles increases Blood flows from the atria to the ventricles Match the following cardiac cycle events in the correct order like from First to last Intraventricular pressure increases to more than the pressure in the aorta Blood flows from the ventricles to arteries Volume of ventricles decreases Ventricles contract Intraventricular pressure decreases to less than the pressure in the atria Atrioventricular valves open Ventricles relax Volume of ventricles increases Blood flows from the atria to the ventricles Intraventricular pressure increases to more than the pressure in the aorta Blood flows from the ventricles to arteries Volume of ventricles decreases Ventricles contract Intraventricular pressure decreases to less than the pressure in the atria Atrioventricular valves open Ventricles relax Volume of ventricles increases Blood flows from the atria to the ventricles

Explanation / Answer

Ans

Cardiac cycle is beating of our heart, sequence of events like contraction and relaxation is known as cardiac cycle.At first atria and ventricles are in relax state that mean blood flowing from respective artery to both chamber, Further auricle contract and more blood flow into respective ventricles from auricles as a result volume and pressure within both ventricles increases and due to this auriculo ventricle valve closed after that semilunar valve open and blood flow from ventricles to respective artery so volume and pressure within both venticles decrease.
