• What are the four chambers of the heart?
right atrium, left atrium, right ventricle, left ventricle
• What are the four valves of the heart?
tricuspid valve, bicuspid valve, pulmonary valve, aortic valve

Tricuspid valve
Chordae tendineas
Upper chamber of the heart
Prevents blood movement from R. ventricle to
R. atrium
Membranes around heart
Groove separating left and right ventricles
Prevents blood movement from L. ventricle to
L. atrium
Inner lining of heart chamber
Layer largely composed of cardiac muscle
tissue
Space containing serous fluid to reduce
friction during heartbeats
Drains blood from myocardial capillaries
Supplies blood to heart muscle
Distributes blood to body organs except lungs
Groove separating atrial and ventricular
portions of the heart
The visceral portion of the pericardium on the
surface of the heart
Helps open and close the valve during
contractions
Major

• The first part of a heart sound, lubb
____occurs
contraction when the
during the ventricular_______,
A-V valves are closing.
• The second part of a heart sound,
dupp
____occurs
during ventricular relaxation
______,
when the pulmonary and aortic valves are
closing.
• The external structures
of the heart include the
ventricles, atria, arteries
and veins. Arteries carry
blood away from the
heart while veins carry
blood into the heart. The
vessels colored blue
indicate the transport of
blood with relatively low
content of oxygen and
high content of carbon
dioxide. The vessels
colored red indicate the
transport of blood with
relatively high content of
oxygen and low content
of carbon dioxide.
