Exploring the Role of the Cardiovascular System in Exercise

The video tutorial explains how the cardiovascular system functions during exercise, focusing on maintaining body temperature and delivering oxygen to muscles. It details the concept of cardiac output, which is calculated by multiplying heart rate by stroke volume. The tutorial also covers blood pressure, describing how it decreases as it moves through the body. The video concludes with an invitation to explore more learning resources.

What does the cardiovascular system work to maintain during exercise?

• Energy levels

• Muscle mass

• Body temperature

• Heart rate

What is necessary for aerobic respiration in muscles during exercise?

• Water

• Oxygen

• Glucose

• Protein

How is cardiac output calculated?

• Heart rate - Stroke volume

• Heart rate x Stroke volume

• Heart rate / Stroke volume

• Heart rate + Stroke volume

What varies from person to person affecting cardiac output?

• Heart rate

• Blood type

• Stroke volume

• Blood pressure

What does blood pressure measure?

• The speed of blood flow

• The volume of blood

• The oxygen content in blood

• The force of blood against vessel walls

How does blood pressure change as it moves through the body?

• Fluctuates

• Remains constant

• Decreases

• Increases
