Correct Answer: Increase in venous capacitance
Description: Sympathetic stimulation causes
- Heart-
Positive chronotropic- Increased heart rate
Positive ionotropic- Increased contractility
Positive dromotropic- Increased conduction velocity
Positive bathmotropic- Increased automaticity
Refractory period decreased in cardiac cells
Increased stroke volume, cardiac output and blood pressure
- Blood vessels
Increased peripheral resistance- Arteriolar constriction
Decreased venous capacitance- Venoconstriction
