In what ways does the circulatory system act like a network of highways in the human body?

Multiple Choice

Why is the human circulatory system considered essential for survival?

• Because it helps in digestion

• Because it transports water, nutrients, and oxygen to cells

• Because it controls movement

• Because it produces energy

Describe how the structure of capillaries supports their function in the circulatory system.

Multiple Choice

What is the main function of arteries in the circulatory system?

• To carry blood away from the heart to the body cells

• To carry blood toward the heart from the body cells

• To exchange gases and nutrients with body tissues

• To filter waste from the blood

Multiple Choice

Which of the following statements about veins is correct?

• Veins carry blood away from the heart

• The largest vein is called the vena cava

• The smallest veins are called arterioles

• Veins have thick and elastic walls

Explain the difference between coronary, pulmonary, and systemic circulation.

Open Ended

Systemic circulation has three branches that are of equal importance. Name one of these branches and describe its function.

Multiple Select

Which of the following statements about pulmonary and systemic circulation are correct?

• Pulmonary circulation carries oxygen-rich blood from the heart to the body.

• Systemic circulation carries oxygen-poor blood to the lungs.

• Pulmonary circulation involves the exchange of gases in the lungs.

• Systemic circulation delivers oxygen and nutrients to body cells.

Fill in the Blanks

The circulatory system is responsible for transporting water, nutrients, and

to the body cells.
