Understanding Blood Pressure and Heart Function

Why is it crucial to keep blood pressure under control?

• To increase blood flow to the brain

• To prevent damage to the heart and blood vessels

• To enhance muscle growth

• To improve digestion

What are the two main factors that affect blood pressure in the vessels?

• Diet and exercise

• Temperature and humidity

• Flow and resistance

• Heart rate and oxygen levels

What happens to resistance when blood vessels become narrower?

• Resistance decreases

• Resistance increases

• Resistance fluctuates

• Resistance remains the same

How does the heart respond to increased arterial pressure?

• By decreasing its size

• By increasing its muscle mass

• By slowing down its rate

• By reducing blood flow

What is a potential consequence of heart hypertrophy?

• Improved heart efficiency

• Increased blood volume

• Early manifestation of heart failure

• Enhanced oxygen delivery
