exchange.
Which type of blood vessel has thick, muscular walls?
Arteries.
What do capillaries connect?
Arteries and veins.
True or False: Veins have valves to prevent backflow of blood.
True.
What is the role of the aorta?
To carry oxygenated blood from the heart to the body.
Multiple choice: Which blood vessel carries deoxygenated blood from the body to the heart? A) Aorta B) Pulmonary vein C) Vena cava D) Artery
C) Vena cava.
What is the significance of the pulmonary arteries?
They carry deoxygenated blood from the heart to the lungs.
Fill in the blank: Blood pressure is highest in ________.
arteries.
What type of blood vessel allows for nutrient and gas exchange?
Capillaries.
True or False: Arteries carry oxygenated blood only.
False.
What is the main difference between arteries and veins?
Arteries have thicker walls and carry blood away from the heart, while veins have thinner walls and carry blood toward the heart.
Multiple choice: Which of the following carries oxygenated blood? A) Pulmonary artery B) Aorta C) Vena cava D) Femoral vein
B) Aorta.
What is the structure of capillaries?
They have thin walls, one cell thick.
Fill in the blank: The ________ is the largest vein in the body.
vena cava.
What adaptation do veins have to assist blood flow?
Valves to prevent backflow.
True or False: Blood in the pulmonary veins is deoxygenated.
False.
What type of blood vessel is primarily involved in regulating blood flow?
Arteries, through vasoconstriction and vasodilation.
Multiple choice: Which blood vessel returns blood from the lungs to the heart? A) Pulmonary artery B) Pulmonary vein C) Aorta D) Coronary artery
B) Pulmonary vein.
Fill in the blank: The ________ helps maintain blood pressure during diastole.
elasticity of arteries.
What is the primary role of the coronary arteries?
To supply blood to the heart muscle.
True or False: Arteries transport oxygen-rich blood and veins transport oxygen-poor blood.
Generally true, but not in the case of pulmonary vessels.
What is the role of venules?
To collect blood from capillaries and drain into veins.
Fill in the blank: The ________ is the blood vessel that supplies blood to the liver.
