The Human Body in Health and Illness by Barbara Herlihy
Questions with Answers
Aorta - correct answers Largest artery in the body
Arteries - correct answers Blood vessels that carry blood away from the heart
Arterioles - correct answers smallest arteries
capacitance vessels - correct answersthe term for veins because they have the ability to stretch. they
have a large diameter and are more distensible to hold more blood. this reduces stress on the heart.
Capillaries - correct answersMicroscopic vessel through which exchanges take place between the blood
and cells of the body
Circle of Willis - correct answersA circle of arteries at the base of the brain that supply blood to the brain
conductance vessels - correct answersBlood vessels that are primarily concerned with carrying blood to
smaller blood vessels; functional name for arteries.
ductus arteriosus - correct answersa blood vessel in a fetus that bypasses pulmonary circulation by
connecting the pulmonary artery directly to the ascending aorta
ductus venosus - correct answersconnects the umbilical vein to the inferior vena cava, bypassing the liver
exchange vessels - correct answersCapillaries are also known as _____.
fetal circulation - correct answersthe system of blood vessels and structures through which blood moves
in a fetus
foramen ovale - correct answersconnects the two atria in the fetal heart
, hepatic portal system - correct answersthe veins that carry blood from the digestive organs to the liver
pulmonary circulation - correct answersflow of blood from the heart to the lungs and back to the heart
pulse - correct answersBeat of the heart as felt through the walls of the arteries.
Resistance vessels (arterioles) - correct answerssmall diameter with a few layers of smooth muscle;
contraction or relaxation of that muscle creates great changes in diameter, and thus great changes in
resistance to blood flow
systemic circulation - correct answerscirculation that supplies blood to all the body except to the lungs
umbilical arteries - correct answerscarry deoxygenated blood from the fetus to the placenta
umbilical vein - correct answersdelivers oxygenated blood from the placenta to the fetus
Veins - correct answersBlood vessels that carry blood back to the heart
venae cavae (vena cava) - correct answerstwo large blood vessels that drain oxygen-poor blood from the
veins into the right side of the heart
Venules - correct answerssmall vessels that gather blood from the capillaries into the veins
tunica intima - correct answersthe innermost layer of a blood vessel
tunica media - correct answersThe middle and thickest layer of tissue of a blood vessel wall, composed
of elastic tissue and smooth muscle cells that allow the vessel to expand or contract in response to
changes in blood pressure and tissue demand.
tunica adventitia - correct answersThe outer layer of tissue of a blood vessel wall, composed of elastic
and fibrous connective tissue.
