Exploring the Cardiovascular System

What is the primary function of the cardiovascular system?

• To produce hormones

• To transport blood, nutrients, and oxygen to cells and remove waste products

• To digest food

• To store energy

Which type of blood vessel carries oxygen-rich blood away from the heart?

• Veins

• Capillaries

• Arteries

• Lymph vessels

What is the function of the valves in veins?

• To increase blood pressure

• To prevent blood from flowing backward

• To oxygenate the blood

• To filter waste products

Which chamber of the heart receives oxygen-poor blood from the body?

• Left Atrium

• Right Atrium

• Left Ventricle

• Right Ventricle

What is the role of the left ventricle in the heart?

• To pump oxygen-poor blood to the lungs

• To receive oxygen-rich blood from the lungs

• To pump oxygen-rich blood to the rest of the body

• To receive oxygen-poor blood from the body

What is the main purpose of the pulmonary circulation?

• To carry oxygen-rich blood to the body

• To carry oxygen-poor blood to the lungs for oxygenation

• To transport nutrients to the cells

• To remove waste products from the body

In the double circulatory system, what is the function of systemic circulation?

• To carry oxygen-poor blood to the lungs

• To carry oxygen-rich blood to the rest of the body

• To mix oxygenated and deoxygenated blood

• To transport hormones

Which of the following is the smallest type of blood vessel?

• Arteries

• Veins

• Capillaries

• Lymph vessels

How many times does blood pass through the heart in one complete cycle of the double circulatory system?

• Once

• Twice

• Three times

• Four times

What is the main advantage of having a double circulatory system?

• It allows for the mixing of oxygenated and deoxygenated blood

• It ensures efficient oxygen delivery and waste removal

• It reduces the heart rate

• It increases blood pressure
