Blood Vessels Quiz

What are the three types of blood vessels?

• Femoral artery, radial artery, carotid artery

• Aorta, pulmonary artery, vena cava

• Red blood cells, white blood cells, platelets

• Arteries, veins, and capillaries

What is the function of arteries?

• To carry deoxygenated blood away from the heart

• To carry nutrients to the heart

• To carry waste products away from the body

• To carry oxygenated blood away from the heart to the rest of the body.

What is the function of capillaries?

• Exchange of oxygen, nutrients, and waste products

• Regulation of body temperature

• Transport of hormones and enzymes

• Storage of excess nutrients

What is the function of veins?

• Regulate body temperature

• Carry deoxygenated blood back to the heart

• Help in digestion of food

• Transport oxygenated blood away from the heart

Explain the structure of an artery.

• The structure of an artery consists of two main layers: the tunica media and tunica externa.

• The structure of an artery consists of only one layer: the tunica intima.

• The structure of an artery consists thick layer and small lumen

• The structure of an artery consists of four main layers: the tunica intima, tunica media, tunica externa, and tunica interna.

Explain the structure of a vein.

• Veins have a layer of bone tissue called tunica media

• Veins have a thick outer layer called tunica externa

• Veins have an outer layer of endothelial cells called tunica intima

• Veins have a thin outer layer and large lumen

Explain the structure of a capillary.

• Multiple layers of smooth muscle cells

• Hollow center filled with red blood cells

• Thick outer layer made of connective tissue

• Single layer of cells one cell thick

What is the role of blood vessels in the circulatory system?

• Regulating body temperature

• Transporting blood throughout the body

• Producing red blood cells

• Carrying oxygen to the lungs

What is the difference between arteries and veins?

• Arteries and veins both carry oxygenated blood away from the heart.

• Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart.

• Arteries carry deoxygenated blood away from the heart, while veins carry oxygenated blood back to the heart.

• Arteries and veins both carry deoxygenated blood back to the heart.

How do blood vessels help in maintaining blood pressure?

• By producing more blood cells to increase pressure

• By changing the color of the blood to control pressure

• By secreting hormones to regulate blood pressure

• By constricting or dilating to regulate blood flow and adjusting vessel diameter to control resistance.
