________________________________

1) If cardiac supply of vagus nerve is cut then Rate of heart beat increases.

2) Blood pressure increases and heart rate decreases in response to With the increase in intra-cranial pressure, the cerebral blood flow is reduced.

• This increased pressure also stimulates the vasomotor centre and increases systemic blood pressure.

3) Systolic pressure of heart is higher than diastolic pressure, because Blood is forcefully pumped into arteries by the heart during systole and not during diastole.
