Week 7 Flashcards
which blood vessels carry blood away from the heart
arteries
which blood vessels will have walls only one cell thick
capillaries
the pulmonary semilunar valve prevents blood from back flowing into the
right ventricle
the systemic circuit circulates blood from the __ to all the body organs except the lungs
left ventricle to right atrium
systole occurs when the
heart tissue is contracting
contraction of the right ventricle forces blood initially into the
pulmonary vein
the pacemaker of the heart is termed as the
SA node
if a person has a blood pressure of 120/80 the “120” refers to the
systole
oxygenated blood enters the heart at the
left atrium
the blood vessel that provides oxygen to the heart
coronary artery
the blood that enters the coronary artery comes from the
aorta
a person with normal blood volume and white cell count but low red cell count or low hemoglobin may be suffering from
anemia
neutrophils and lymphocytes are types of
leukocytes
platelets
initiate blood clotting
which type of blood vessel allows exchange of material between the blood and the tissues
capillaries
what is the function of the heart valves
to prevent backflow
arteries
carry blood away from the heart
the superior and inferior vena cava
carry blood to the right atrium
the coronary arteries carry blood
from the aorta to the heart
the SA node
initiates the heartbeat
