BLOOD VESSELS AND CIRCULATION Flashcards
which transport blood from the right
ventricle of the heart through the lungs and back to the left atrium
PULMONARY VESSELS
which transport blood from the left
ventricle of the heart through all parts of the body and back to
the right atrium
systemic vessels
carry blood away from the heart; usually, the blood is oxygenated (
arteries
where exchange of substances such as O2,
CO2, nutrients, and other waste products occurs between the blood
and the tissue fluid
capillaries
carry blood toward the heart; usually, the blood is deoxygenated
veins
Blood flow through capillary
networks is regulated by smooth muscle cells called
precapillary
sphincters.
the system of blood vessels that
carries blood from the right ventricle of the heart to the lungs and
back to the left atrium of the heart.
pulmonary circulation
the system of blood vessels that carries
blood from the left ventricle of the heart to the tissues of the body
and back to the right atrium.
systemic circulation
All arteries of the systemic circulation branch directly or indirectly
from the
aorta
the part of the aorta that passes superiorly from the left ventricle
ascending aorta
The aorta arches posteriorly and to the left as the
aortic arch
the longest part of the aorta
descending aorta
Blood pressure measurements
are normally taken from the
brachial artery
a measure of the force blood exerts against the
blood vessel walls.
blood pressure
the pressure reaches a maximum value called the
systolic pressure
