17. MUSCULATURE OF THE
HEART

18. CHAMBERS OF THE HEART
THE RIGHT ATRIUM
It is the right upper
chamber of the heart.
Receives venous blood
from the whole body.
Pumps into the right
ventricle.
Forms the right
border,part of upper
border and base of the
heart.

19. THE RIGHT VENTRICLE
It is a triangular chamber.
It receives blood from the
right atrium.
Pumps it to the lungs
through pulmonary trunk
and arteries.
It forms the inferior border
and the sternocostal
surface of the heart.
It has two
surfaces,anterior and
inferior.

20. THE LEFT ATRIUM
It is a quadrangular
chamber.
It forms the left two-thirds
of the base of the
heart,greater part of upper
border,part of anterior
surface and left border.
It receives oxygenated
blood from lungs through
four pulmonary veins.
And pumps it into te left
ventricle through left atrio-
ventricular orifice.

21. THE LEFT VENTRICLE
It forms the apex of the
heart,a part of the anterior
surface,left
surface,inferior surface
and left border.
It receives oxygenated
blood from left atrium.
Pumps it into the aorta.
Interventricular septum-its
upper part seperates not
only two ventricles but
also right atrium and left
ventricle.

22. VALVES OF THE HEART
Valves maintain unidirectional flow of blood.
Prevents its regurgitation in opposite direction.
There are two pairs of valves.
a)) atrioventricular pair
b))semilunar pair
These valves have cusps.
CUSPS-they are folds of endocardium,strengthene
by fibrous tissue.

23. ATRIOVENTRICULAR
VALVE
There are two
atrioventricular valves,
right and left.
Both are made up of
fibrous
ring,cusps,chorda
tendini,papillary
muscles.

24. Right atrioventricular
valve
Left atrioventriclar
valve
Also called as tricuspid
valve.
Has three
cusps.anterior,posterior and
septal.
Admits the tip of three
fingers.
Also called as bicuspid or
mitral valve.
Has two cusps.anterior and
posterior.
Admits the tip of two fingers.

25. SEMILUNAR VALVES-there are
two semilunar valves. Right and left.
RIGHT VALVE LEFT VALVE
Right valve is commonly
known as the pulmonary
valve.
It has three cusps.
It does not have a fibrous
ring.
Left valve is commonly
known as aortic valve.
It has three cusps.
It does not have a fibrous
ring.

30. RIGHT CORONARY ART. LEFT CORONARY ART.
1)It is larger than the right.
2)Branches-1)branches to the
inferior surface.
2)ant.
interventricular
3)Area supplied-
Left atrium
Small part of rt. Ventricle.
Greater part of left Ventricle
Ant. Part of interventricular
septum.
Left branch of the A.V.
bundle.
1)It is smaller than the left.
2)branches-1)marginal
2)post.
interventricular
3)Area supplied-
Rt. Atrium
Greater part of rt. Ventricle.
Smaller part of left ventricle.
Post. Part of interventricular
septum.
Entire conducting sytem except
left branch of the A.V. bundle.

31. VEINS

32. STRUCTURE OF WALL
OF A VEIN

33. VENOUS SYSTEM OF THE
HEART
Great cardiac vein
Middle cardiac vein
Right marginal vein
Vein supplying the rt. And
left atrium.
Anterior cardiac vein
Thebesian veins
Beyond the anterior cardiac
vein and the thebesian veins
all the remaining veins drain
into the coronary sinus
while they drain directly into
the rt.atrium.
