Role
 of
 Mitral
 Valve
 in
 a
 Healthy
  gracious
 Heart The
 heart
 is
 a
 four-­?chambered
 pump,
 which,
 due
 to
 its
  composite
 construc6on,
 pumps
 su?cient
 volumes
 of
  oxygen
 and
 nutrient-­?rich
  inception
 to
 all
 parts
 of
 the
  gentlemans gentleman
 system.
 It
 
 has
 two,
 small,
 atria
 and
 two,
 larger,
  ventricles;
 the
 mitral
 valve
 (also
 called
 the
 bicuspid
 valve),
 is
 one
 of
 the
 two
 atrioventricular
 valves
  install
 in
  the
 heart,
 it
 separates
 the
 leB
 atrium
 from
 the
 leB
 ventricle.
 The
 valve
 is
 composed
 of
 two
 cusps
 and
 is
  surrounded
 by
 a
 ring
 of
 6ssue
 called
 the
 mitral
 annuIus.
 It
 is
 named
 the
 mitral
 valve
 as
 the
 two
 cusps
 of
 the
  valves

 to
 form
 a
 shape
 resembling
 a
 bishops
 mitre.
  Blood
 entering
 the
 leB
 atrium,
 is
 doing
 so
 via
 the
 pulmonary
 veins
 and
 is
 therefore
 oxygenated.




 The
 blood
  then
 passes
 through
 the
 mitral
 valve
 and
 into
 the
 leB
 ventricle,
 which
 is
 the
 chamber
 of
 the
 heart
 which
  produces
 the
  or so
 contrac6le
 force;
 this
 blood
 is
 then
 distributed
 to
 all
 parts
 of
 the
  tree trunk
 via
 the
 Aorta. The
 mechanism
 of
 the
 atrioventricular
 valves
 
 relies
 upon
 pressure
 di?erences
 between
 communica6ng
  parts
 of
 the
 heart.
 When
 ventricular
 pressure
 is
 less
 than
 atrial
 pressure,

 valves
