THE HEART Flashcards
pumps the blood to your right
ventricle.
RIGHT ATRIUM
It collects deoxygenated blood from the bloodstream and
moves it into the heart’s right ventricle.
RIGHT AURICLE
upper chamber
pumps the blood to your left ventricle.
LEFT ATRIUM
Receives oxygenated blood from the lungs via the pulmonary
veins.
LEFT AURICLE
Pumps deoxygenated blood to the lungs where gas exchange
occurs.
RIGHT VENTRICLE
It pumps oxygen-rich blood to the rest of your body
LEFT VENTRICLE
a used as a passageway by
two major vessels of the heart: the anterior
interventricular artery and great cardiac vein
INTERVENTRICULAR SULCUS
the biggest supplier of oxygenated blood to your heart’s
lower left pumping chamber or ventricle.
ANTERIOR INTERVENTRICULAR ARTERY
drains blood from the left side of the heart wall tissue
GREAT CARDIAC VEIN
drains blood from the right margin of the heart wall tissue
SMALL CARDIAC VEIN
provides blood to the right ventricle, right atrium, and the
SA (sinoatrial) and AV (atrioventricular) nodes, which control
the heart rhythm.
RIGHT CORONARY ARTERY
Supplies blood to the left atrium and the side and back of
the left ventricle.
CIRCUMFLEX ARTERY
supplies blood to the left side of the heart muscle
LEFT CORONARY ARTERY
the outermost tissue layer that surrounds all vertebrate
hearts, is critical for cardiac development and regeneration,
and has been linked to potential cardiac repair procedures.
EPICARDIUM
is one of the heart’s four valves. It controls blood flow
between the upper left chamber (left atrium) and the lower
left chamber (left ventricle).
MITRAL VALVE
also known as the right atrioventricular valve, controls the
flow of blood from the heart’s top chamber (right atrium) to
the bottom chamber (right ventricle).
TRICUSPID VALVE
form the leaflet suspension system, which ultimately
determines and maintains the position and tension of the
valve leaflets at the end of systole.
CHORDAE TENDINEAE
located in the ventricles of the heart. They adhere to the
cusps of the atrioventricular valves via the chordae
tendineae and contract to prevent inversion or prolapse of
these valves during systole.
PAPILLARY MUSCLE
one of four heart valves that oxygenated blood passes
through before leaving the heart. It is also known as the
aortic semilunar because of its semilunar shape. It is located
between the left ventricle and the aorta, preventing oxygenrich blood from returning to the left ventricle.
AORTIC SEMILUNAR VALVE
The pulmonary heart valve opens, allowing deoxygenated
blood to exit the right ventricle and enter the lungs via the
pulmonary artery.
PULMONARY SEMILUNAR VALVE
Blood returned to the left side of the heart is pumped out of
the heart into the aorta from which the systemic arteries
branch to supply essentially all body tissues.
AORTA
The pulmonary trunk splits into the right and left pulmonary
arteries, which carry blood to the lungs, where oxygen is
picked up and carbon dioxide is unloaded.
PULMONARY ARTERY
Deoxygenated blood from the head, neck, thorax, and upper
limbs is returned to the right atrium
SUPERIOR VENA CAVA
Deoxygenated blood from the abdomen, pelvis, and lower
limbs is returned to the right atrium
INFERIOR VENA CAVA
