By Dr. BPS Tyagi Cardiovascular System Changes
- Heart Rate: The heart rate becomes less variable as we age. This means the heart may take longer to respond to changes in physical activity or stress.
- Blood Pressure: Blood pressure may increase due to the stiffening of arteries and blood vessels.
- Cardiac Output: The heart’s ability to pump blood efficiently may decrease, especially during exertion.
- Circulatory System: Blood vessels lose some elasticity, making it harder for the heart to pump blood efficiently.
