Open Ended

Why is the circulatory system important for the survival of mammals?

Fill in the Blanks

Blood flows inside the

in a closed circulatory system.

Multiple Choice

Which components make up the mammal circulatory system?

• Blood vessel, heart, blood

• Heart, lungs, blood

• Blood vessel, artery, vein

• Heart, artery, plasma

Fill in the Blanks

The liquid part of blood is called

.

Open Ended

Explain the significance of the double circulatory system in mammals and how it relates to oxygenated and deoxygenated blood.

Open Ended

Describe the main differences between oxygenated and deoxygenated blood in terms of their direction of flow and gas content.

Multiple Choice

Which type of blood vessel has the thickest wall and why is this important for its function?

• Artery, to withstand high pressure

• Vein, to prevent backflow

• Capillary, to allow exchange

• Arteriole, to regulate flow

Multiple Choice

Which blood vessel carries blood back towards the heart?

• Artery

• Capillary

• Vein

• Aorta

Open Ended

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

Multiple Choice

Which of the following best describes the main structural difference between arteries and veins?

• Arteries have thicker, more elastic walls and no valves, while veins have thinner walls and contain valves.

• Arteries have thinner walls and contain valves, while veins have thicker, more elastic walls and no valves.

• Both arteries and veins have the same wall thickness and no valves.

• Veins carry blood away from the heart, while arteries carry blood to the heart.

Multiple Select

Which of the following statements about arteries is/are correct?

• They carry blood away from the heart.

• They have relatively narrow lumen.

• Their walls contain smooth muscle and elastic fibers.

• They contain valves to prevent backflow.

Fill in the Blanks

The main vein that carries deoxygenated blood from the body into the right atrium is called the

• Smooth muscle

• Endothelium

Multiple Choice

Which of the following structures is present in veins but not in arteries?

• Valves

• Smooth muscle

• Endothelium

• Basement membrane

Open Ended

Describe the main function of capillaries in the circulatory system.

Multiple Select

Which of the following statements about blood vessels is/are correct?

• Arteries carry blood away from the heart under high pressure.

• Veins have thick walls and narrow lumens.

• Capillaries are one cell thick and connect arteries and veins.

• Veins can contain valves to prevent backflow of blood.

Multiple Choice

Identify the blood vessel labeled 'A' in the image.

• Artery
