1. Which blood vessel carries oxygenated blood from the lungs to
the left atrium?: pulmonary veins
2. Where are the elastic arteries located?: near the heart
3. Medium veins do not have internal or elastic laminae and,
therefore, are not able to withstand high pressure (T/F): True

5. Veins generally have very thick walls in relation to their diameter, with
large lumen (T/F): False
6. Which statements are true about veins? Choose 2 answers: they are
more numerous than arteries
they lack smooth muscle

change in the net filtration would one expect with an increase of blood
hydrostatic pressure?: increase
8. When would an active transport mechanism be necessary?: when a
sub- stance must be moved against its concentration gradient
9. Which blood vessel has a very small diameter and is involved
in the circulation of blood to the capillaries?: arteriole

arteriole and a capillary?: metarteriole

elastic fibers?: muscular artery
12. Which type of capillaries has small pores present within them?:
fenestrated capillaries

from the heart

the liver

ensures blood flow to both hemispheres in case of injury?: the circle of
Willis
38. Which artery branches directly off of the brachial artery?: radial
39. Which artery is present near the shoulder joint?: axillary artery
40. Which arteries form arches in the hand, forming enabling collateral
circu- lation?: radial and ulnar arteries

for the lower extremities. (T/F): false
42. Which artery passes under the inguinal ligament and travels
through the thigh?: femoral artery
43. Which vein is present in the elbow?: median cubital vein
44. Which artery supplies the dorsum of the foot?: dorsal pedis
45. Which blood vessel continues from the axillary artery and runs
along the medial side of the arm?: brachial
46. What is the function of the heart?: pumps oxygenated blood to the
body tissues and carbon dioxide to the lungs
47. Which valve opens during right atrial systole?: tricuspid
48. What is the process called when the blood enters the heart at full
capacity before getting released from it?: diastole
49. Systole occurs when the heart chamber is relaxed and filling with
blood. (T/F): false

heart sound?: S4
52. Which nerve helps in regulation of the heart beat?: vagus nerve
53. What reduces the heart beat range?: parasympathetic stimulation
54. Extreme emotional states cause an increase in HR due to which part
of the autonomic nervous system?: sympathetic
55. In which structure does the depolarization occur more frequently
due to the presence of norepinephrine?: sinoatrial node
56. What is the time required to complete one cardiac cycle in a
human being?: 0.8 sec
