• Aorta

• Pulmonary vein

• Vena cava

• Carotid artery

Which arteries branch from the aorta and provide blood to the myocardium?

• Pulmonary arteries

• Coronary arteries

• Carotid arteries

• Femoral arteries

Fill in the blank: The smallest of the arteries, called ______, deliver blood to the capillaries.

• Arterioles

• Venules

• Veins

• Aorta

What is a capillary bed?

• A network of tiny blood vessels

• A large vein

• The left ventricle

• The aorta

Fill in the blank: Arterial blood flows into a capillary bed, and ______ blood flows back out.

• Venous

• Arterial

• Pulmonary

• Oxygenated

Since capillaries are so small in diameter, blood will not flow as quickly as it does in arteries and veins, allowing time for exchange of nutrients, oxygen, and waste material.

• True

• False

Fill in the blank: ______ carry blood back to the heart. Blood leaving capillaries first enters small venules, which then merge into larger veins.

• Veins

• Arteries

• Capillaries

• Aorta

Arteries carry blood ______

• from the heart to the body

• from the body to the heart

• from the brain to the heart

What is the primary difference between arteries and veins in terms of blood flow?

• Arteries carry blood towards the heart, while veins carry blood away from the heart

• Arteries carry oxygenated blood, while veins carry deoxygenated blood

• Arteries carry blood away from the heart, while veins carry blood towards the heart

• There is no significant difference in terms of blood flow

Arteries carry

• oxygenated blood away from the heart
• deoxygenated blood away from the heart
• food to the stomach
• art supplies to class
