Question 11

Reasons why SV can increase?

Answer 11

• Venous return - amount of deox blood returning to heart per MINUTE, pocket valves, muscle pump, respiratory pump, gravity, smooth muscle
• Frank Starling - venous return increase, v wall stretch increase, contraction force increase, stroke volume increase
