Put the phases of the cardiac cycle in the correct order, starting after ventricular filling. a. ventricular ejection, iso-volumetric contraction, iso-volumetric relaxation. b. iso-volumetric contraction, ventricular ejection, iso-volumetric relaxation. c. ventricular ejection, ventricular relaxation, iso-volumetric contraction. d. iso-volumetric relaxation, ventricular ejection, iso-volumetric contraction

Explanation:

Cardiac cycle is performed by our  heart . Cardiac cycle starts from the ending of one heartbeat to the beginning of next heart beat. There is a complete relaxation of both atria and ventricles. Approximately, cardiac cycle lasts 0.8 seconds. The correct order of cardiac cycle is- iso-volumetric contraction, ventricular ejection, iso-volumetric relaxation.

b. isovolumetric contraction, ventricular ejection, isovolumetric relaxation

Explanation:

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
