Short Term effects of Exercise on the cardiovascular system

What is the immediate effect of exercise on heart rate?

• Heart rate decreases

• Heart rate remains the same

• Heart rate increases

• Heart rate stops

How does systolic blood pressure change during short-term exercise?

• It decreases

• It remains constant

• It increases

• It fluctuates randomly

What happens to oxygen consumption during exercise?

• It decreases

• It remains unchanged

• It increases

• It becomes zero

Which of the following is a method the body uses to regulate temperature during exercise?

• Decreasing blood flow to the skin

• Sweating

• Shivering

• Increasing heart rate

What is stroke volume?

• The amount of blood pumped by the heart per minute

• The amount of blood pumped by the heart per beat

• The number of heartbeats per minute

• The pressure of blood against artery walls

How does cardiac output change during exercise?

• It decreases

• It remains the same

• It increases

• It stops

What is the formula for calculating cardiac output?

• Cardiac Output = Heart Rate × Stroke Volume

• Cardiac Output = Stroke Volume ÷ Heart Rate

• Cardiac Output = Heart Rate + Stroke Volume

• Cardiac Output = Heart Rate - Stroke Volume

Which of the following best describes the change in heart rate during the initial stages of exercise?

• It decreases gradually

• It remains constant

• It increases rapidly

• It fluctuates without pattern

What is the primary reason for the increase in oxygen consumption during exercise?

• To cool down the body

• To provide energy for muscle activity

• To increase blood pressure

• To decrease heart rate
