Blood Vessels Quiz

How does blood flow from the heart to organs and back to the heart?

• Through the digestive system

• Through the respiratory system

• Through the circulatory system

• Through the nervous system

What are the three layers of blood vessels?

• Endothelium, Myocardium, Epicardium

• Endothelium, Smooth muscle, Connective tissue

• Epidermis, Dermis, Hypodermis

• Pericardium, Myocardium, Endocardium

Describe the tunica intima layer.

• The innermost layer of a blood vessel

• A layer of muscle tissue

• The outermost layer of a blood vessel

• A type of connective tissue

Describe the tunica media layer.

• It is the middle layer of arteries and veins composed of smooth muscle cells and elastic fibers.

• It is the outermost layer of blood vessels, primarily made of connective tissue.

• It is the innermost layer of blood vessels, consisting of endothelial cells.

• It is a type of muscle tissue that is not related to blood vessels.

Describe the tunica externa layer.

• It is the outermost layer of a blood vessel, composed of connective tissue.

• It is the middle layer of a blood vessel, primarily made of smooth muscle.

• It is the innermost layer of a blood vessel, consisting of endothelial cells.

• It is a type of muscle tissue found in the heart.

What is the one type of blood vessel that only has the tunica intima?

• Arteries

• Veins

• Capillaries

• Arterioles

What direction do arteries transport blood in relation to the heart?

• Away from the heart

• Towards the heart

• In a circular motion around the heart

• Arteries do not transport blood

Do arteries carry oxygenated or deoxygenated blood?

• Oxygenated blood

• Deoxygenated blood

• Both

• None of the above

What are the two types of arteries?

• Pulmonary and Systemic

• Aorta and Vein

• Capillary and Vein

• Pulmonary and Vein

Which of the following best describes elastic arteries?

• They are blood vessels that carry blood away from the heart.

• They are the smallest type of arteries.

• They contain a high density of elastic fibers, allowing them to stretch in response to each pulse of the heart.

• They are primarily involved in the regulation of blood pressure.
