Answer 2

Stop blowing on syringe

Blowing into syringe causes ^ interthorasic pressure =

Decrease in Venus return via SVC & IVC =

Barrorreceptors detect the pressure change and the decrease in BP=

This stimulates the ^ HR and vasoconstriction to compensate

Interthorasic pressure drops and mass of Venus return begins = ^BP

Barrowreceptors detect the pressure change again =

Decrease in HR which will revert back to NSR
