When a person stands up suddenly, gravity causes blood to pool in the lower extremities, temporarily reducing blood flow to the brain. To counteract this, the body quickly activates the autonomic nervous system, leading to vasoconstriction and increased heart rate to maintain blood pressure and ensure adequate blood flow to the brain. This rapid response helps prevent dizziness or fainting that can occur from the sudden change in position.
