How much the cardiac tissue can stretch during the diastole phase is described by which term?

Explanation:
During diastole the heart muscle relaxes and the chambers fill with blood. The term that describes how much the cardiac tissue can stretch to accommodate that filling is elasticity of the cardiac fibres. A more elastic (stretchable) myocardium can lengthen more when filled, affecting how much blood the heart can hold before it contracts again. This differs from stroke volume (the amount ejected per beat), venous return (the amount returning to the heart), and cardiac output (the overall volume pumped per minute).
