HUMAN HEART ANATOMY
Figure 21.2. Location of the
Heart in the Thoracic Cavity.
The heart is situated within the middle
portion
of
the
mediastinum,
immediately posterior to the sternum.
(a) Anterior view of the open chest
cavity, showing the position of the
heart and major vessels relative to the
lungs. The sectional plane indicates the
orientation
of
part
(c).
(b)
Relationships between the heart and the
pericardial cavity. The pericardial
cavity surrounds the heart like the
balloon surrounds the fist (right).
(c) Diagrammatic view showing the position of the
heart and the location of other organs within the
mediastinum. In this sectional view, the heart is
shown intact so you can see the orientation of the
major vessels. (d) A superior view of a horizontal
section through the trunk at the level of vertebra T8.
