1. name the structure and whether it contains oxy- right atrium; deoxy-
genated or deoxygenated blood genated
2. name the structure aortic semilunar valve
3. oxygen is carried by cells. it binds to erythrocytes; hemo-
proteins called that contain iron globin
4. of the formed elements, which cells are responsi- leukocytes, platelets,
ble for immune function, clotting, and gas trans- erythrocytes
fer-in that order?
5. what are the major functions of blood? (you must 1) plays a role in im-
name 3) mune function
2) temp regulation
3) pH regulation
4) gas/nutrients/ waste
transport
5) regulates water loss
6. a patient has a stroke volume of 70ml/beat, a heart CO=SVxHR=70ml/beat/
rate of 70 beats/min, a mean arterial pressure of
100, systolic BP of 95 and diastolic BP of 60. cal-

which ions mediate the upstroke, plateau, and upstroke=sodium; de-
downstroke of a cardiac action potential. indicate polarization
the contraction phase that correlates to these plateau=calcium; con-

um; relaxation
8. what are the three layers of the heart? epicardium, myocardi-
um, endocardium
9. what is the fluid filled sac called that surrounds pericardium
the heart?
10. when red blood cells get broken down, the iron transferrin
molecule is transferred from the macrophage to
the liver with which transfer protein?
11. Which wave indicates atrial depolarization? P wave
