3. BROKEN HEART SYNDROME Is there such a thing a broken heart?

4. 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

5. Vascular System Arteries and arterioles – ______________________________________ Capillaries – _______________________________________ Veins and venules – _______________________________________

7. 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 ________________________________

9. 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

10. Comparison of the Pulmonary and Systemic Circulation

11. 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 ________________________

12. 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 semi- lunar valve into the __________________.  The blood then flows to the __________________________

13. 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

14. Erythrocytes and Hemoglobin Bind and transport ______ and _______ in the blood – Amount of oxygen carried in blood depends on ________________________________(PO 2 ) – __________ in lungs, hemoglobin binds easily to oxygen,_________at tissues, unbinds oxygen - tissues Protein made up of iron
