In a sentence or two each, explain how each of the structural adaptations would improve stroke volume. Hint: stroke volume is related to EDV (filling), ESV (contractility), AND Frank-Starling mechanism. Also keep in mind the concept of pre-load and after-load. Therefore, explain how the structure could affect some or all of those components.
Increased LV internal diameter
Increased LV mass
Increased LV wall-thickness
Increased Atrial thickness
Increased aortic compliance
Increased plasma volume
Increased muscle capillary volume
