Correct Verified Answers
Location, size, and position of heart
✓ A triangular, hollow organ, shaped and sized roughly like a closed fist; located
between the lungs in the lower portion of the mediastinum; and positioned in
the thoracic cavity between the sternum in front and the bodies of the thoracic
vertebrae behind. 2/3 of the heart is to the left of the midline of the thoracic
cavity and 1/3 of the heart is to the right of the midline of the thoracic cavity.
Apex of the heart
✓ Lower edge of the heart that lies on the diaphragm and points toward the left;
located in the space between the fifth and sixth ribs on a line even with the
midpoint of the left clavicle; physicians and nurses often place a stethoscope on
the chest, directly over the apex, and listen for the apical beat.
Cardiopulmonary Resuscitation (CPR)
✓ Rhythmic compression of the heart combined with effective artificial respiration
to maintain blood flow through the body in cases of cardiac arrest.
Atria (singular: atrium)
✓ Upper receiving chambers of the right and left side of heart (right atrium, left
atrium)
Ventricles
Top Mark !!!
, Top Mark Questions and Correct Verified Answers
✓ Lower discharging chambers of the right and left side of the heart (right
ventricle, left ventricle)
Auricle
✓ Earlike extension, extending from each atrium.
Myocardium
✓ Thick middle muscle layer of the heart
Interatrial septum
✓ Partition between the right and left atrium
Interventricular septum
✓ Partition between the right and left ventricles
Endocarium
✓ A layer of thin, smooth tissue lining each chamber of the heart; inner lining of
the heart
Endocarditis
✓ Inflammation of the inner lining of the heart (endocardium); can be fatal
because inflammation of this lining may cause it to become rough and abrasive.
This texture triggers red blood cells to release platelet factors that can form a
deadly blood clot.
Thrombus
