does the right atrium have oxygenated or deoxygenated blood? - ANSWER ✔✔-deoxygenated
oxygen is carried by _____ cells. It binds to proteins called _____ that contain iron. - ANSWER ✔✔-
erythrocytes; hemoglobin
which element is responsible for immune function, clotting, and gas transfer? (in this particular order) -
ANSWER ✔✔-leukocytes; platelets; erythrocytes
what are the major functions of blood? - ANSWER ✔✔-- plays a role in immune function
- temperature regulation

a patient has a stroke volume of 70ml/beat, a heart rate of 70 beats per minute, a mean arterial pressure
of 100, systolic BP of 95 and diastolic BP of 60. Calculate the output of this patient. - ANSWER ✔✔-CO =
SV x HR
70 x 70 = 4900ml/min
= 4.9L/min
