Question
Blood pressure increases and heart rate decreases in response to :
exercise
haemorrhage
exposure to high altitude
increased intracranial pressure
Solution
D.
increased intracranial pressure
Intracranial pressure (ICP) is a measurement of the pressure of brain tissue and the cerebrospinal fluid that cushions and surrounds the brain and spinal cord. It is used to monitor the health of the brain after an injury.
If intracranial pressure is rapidly increased, the cerebral blood flow is. The increase in intracranial pressure stimulates the vasomotor centre and increases systemic blood pressure. It means blood pressure increases and heart rate decreases.
