HEART STRUCTURE & FUNCTION MICROCIRCULATION
HEART VALV E S
• There are four chambers of the heart: the two upper atria and the
two lower ventricles
• The right atrium receives deoxygenated blood from the body and
then the right ventricle pumps this blood to the lungs to be
oxygenated
• The newly-oxygenated blood travels to the left atrium and the left
ventricle pumps it to the body
• The heart and the blood vessels comprise the cardiovascular
system
• This system circulates blood throughout the body, providing tissues
with nutrients while removing metabolic waste products
• Blue arrows indicate the flow of deoxygenated blood; pink arrows
indicate the flow of oxygenated blood
• The semilunar valve at the
entrance of the pulmonary
trunk is called the pulmonary
valve
• The semilunar valve at the
entrance of the aorta is called
the aortic valve
• The valve between the right
atrium and ventricle is called
the tricuspid valve, due to its
three cusps
• The valve between the left
atrium and ventricle has two
cusps (as shown here) and is
referred to as the bicuspid
(mitral) valve
