BROKEN HEART SYNDROME
Is there such a thing a broken heart?
Cardiovascular System
Overview
 A ______ chambered muscular pump
 Located in the _______________________
 Connected to an extensive system of blood
vessels which brings _________ and __________
to all body cells and removes wastes
 Outputs ___________of blood per minute at rest
 The system maintains body temperature and
appropriate fluid levels to prevent dehydration
Vascular System
• Arteries and arterioles
– ______________________________________
• Capillaries
– _______________________________________
• Veins and venules
– _______________________________________
The Heart
specialized muscle tissue called cardiac muscle or
__________________
a muscle that requires _____delivery and
________________
it is the size of a fist (approximately) 250 – 300 grams
considered a _______________________
_____ chambers

The Heart
__________side pumps deoxygenated blood
(dark red) from ___________to the_______~
__________________________
_______ side pumps oxygenated blood
(bright red) from the________to
__________~ _________________________
Coronary Circulation – coronary arteries and
veins supply and drain the myocardium
Comparison of
the Pulmonary
and Systemic
Circulation
PULMONARY CIRCULATION
 Poorly oxygenated blood collects in the
______________________and the ________________________
 The superior and inferior vena cava empty into the ______________
 The ______________________(which brings blood back from the
heart itself) also empties into the right atrium.
 The right atrium is the______________of the two atria
although it receives the same amount of blood.
 The blood is then pumped through the ______________, or
atrioventricular, valve into the __________________.
 The blood then is pumped through the pulmonary ______________
valve into the ____________________.
This blood leaves the heart by ______________________and travels
through the lungs (_____________________________)
 Then into the ________________________
SYSTEMIC CIRCULATION
 The oxygenated blood then enters the ________________.
 The blood then travels through the
____________________also called mitral or left atrioventricular
valve, into the ______________________.
 The left ventricle is _______________ and more muscular
than the right ventricle because it pumps blood at a
______________ pressure.
 Also, the right ventricle cannot be too powerful or it would
cause ________________________in the lungs.
 From the left ventricle, blood is pumped through the semilunar valve into the __________________.
 The blood then flows to the __________________________
And the Process Will Continue
the blood goes through peripheral tissues
 They will ________________________from the blood,
 which will again be collected inside the _______________and the
process will continue.
 Peripheral tissues do not fully deoxygenate the blood, thus
venous blood does have _________________only in a lower
concentration in comparison to arterial blood.
 The release of oxygen from __________________is regulated.
 The diffusion of oxygen from red blood cells increases with an
increase of carbon dioxide in tissues, increase in temperature, or a
decrease in pH.
 Such characteristics are exhibited by tissues undergoing high
metabolism, as they require increased levels of oxygen
Erythrocytes and Hemoglobin
• Bind and transport ______ and _______ in the
blood
– Amount of oxygen carried in blood depends on
________________________________(PO2)
– __________ in lungs, hemoglobin binds easily to
oxygen,_________at tissues, unbinds oxygen tissues
• Protein made up of iron
