Veins and Arteries Quiz
Questions: 16 · 10 minutes
1. After becoming oxygenated in the lungs, blood reaches the left atrium through which vessels?
Coronary veins
Pulmonary veins
The superior and inferior venae cavae
Pulmonary arteries
2. Which major vessels carry blood upward through the neck toward the head?
Carotid arteries
Venae cavae
Jugular veins
Pulmonary veins
3. If smooth muscle in an artery contracts and narrows its lumen, what generally happens to resistance to blood flow, assuming other factors remain unchanged?
Resistance decreases because blood moves through a smaller space.
Resistance increases because the passage is narrower.
Resistance remains unchanged because only veins regulate flow.
The artery becomes a vein until its smooth muscle relaxes.
4. Blood ejected from the right ventricle is directed toward the lungs through which vessels?
Pulmonary veins
The aorta
The venae cavae
Pulmonary arteries
5. During walking, calf muscles repeatedly compress nearby veins. How does this help venous return from the legs?
Compression causes capillaries to generate a heartbeat-like pressure wave.
Compression closes the leg arteries so blood can enter the veins.
The calf muscles transfer oxygen directly into venous blood.
Compression pushes blood along, while venous valves help keep it moving toward the heart.
6. A vein and an artery receive the same small increase in blood volume, but the vein stretches more with a smaller pressure increase. What does this illustrate?
Veins are more compliant and can accommodate more blood at relatively low pressure.
Veins generate the main pulse that drives systemic circulation.
Capillaries control how much either vessel can stretch.
Arteries have thinner walls than comparable veins.
7. When you feel a rhythmic pulse at the wrist, what are you detecting?
A vein briefly closing during each inhalation
An artery expanding as a pressure wave passes after a heartbeat
A capillary actively contracting to move blood
A lymphatic vessel responding to muscle movement
8. Blood traveling from the tissues of the foot back toward the heart generally passes through which type of vessel?
Systemic arteries
Coronary arteries
Pulmonary arteries
Systemic veins
9. If an artery supplying part of the lower leg becomes blocked, what is the most direct effect on tissue beyond the blockage?
Venous return from the tissue immediately increases
Capillary exchange accelerates because pressure rises downstream
The tissue receives less oxygenated blood through that arterial route
Venous valves reverse to deliver arterial blood
10. Which major vessels drain blood from the head and neck toward the heart?
Jugular veins
Pulmonary arteries
Coronary arteries
Carotid arteries
11. Which vessels return most systemic blood directly to the right atrium?
The pulmonary veins
The coronary arteries
The superior and inferior venae cavae
The carotid arteries
12. Which sequence correctly traces blood from a systemic artery, through tissue exchange vessels, and back into a systemic vein?
Artery → arteriole → capillary → venule → vein
Artery → capillary → arteriole → venule → vein
Artery → venule → capillary → arteriole → vein
Artery → vein → capillary → arteriole → venule
13. What is the primary role of the coronary arteries?
To carry blood from the brain to the heart
To return blood from the lungs to the left atrium
To supply oxygenated blood to the heart muscle
To connect the aorta directly to the venae cavae
14. Under a microscope, a vessel has a relatively thick muscular wall and keeps a rounder shape than a nearby vessel of similar size. What is it most likely to be?
A capillary
A vein
A lymphatic vessel
An artery
15. What is the main function of valves found in many limb veins?
To create the pressure pulse produced by the heart
To limit backward blood flow as blood returns to the heart
To allow oxygen to diffuse directly into muscle cells
To redirect blood from arteries into lymphatic vessels
16. Which characteristic defines an artery?
It contains valves throughout its entire length.
It always carries oxygen-rich blood.
It carries blood away from the heart.
It is always located deeper than a vein.
