bios 255 exam 1 with questions and correct answers well defined
name the structure and whether it contains oxygenated or deoxygenated blood - correct
answer-right atrium; deoxygenated
name the structure - correct answer-aortic semilunar valve
oxygen is carried by _______ cells. it binds to proteins called ______ that contain iron -
correct answer-erythrocytes; hemoglobin
of the formed elements, which cells are responsible for immune function, clotting, and gas
transfer-in that order? - correct answer-leukocytes, platelets, erythrocytes
what are the major functions of blood? (you must name 3) - correct answer-1) plays a role
in immune function
2) temp regulation
3) pH regulation
4) gas/nutrients/ waste transport
5) regulates water loss
a patient has a stroke volume of 70ml/beat, a heart rate of 70 beats/min, a mean arterial
pressure of 100, systolic BP of 95 and diastolic BP of 60. calculate output of this patient -
correct answer-CO=SVxHR=70ml/beat/min=4900ml/min=4.9L/min
which ions mediate the upstroke, plateau, and downstroke of a cardiac action potential.
indicate the contraction phase that correlates to these events - correct answer-
upstroke=sodium; depolarization
plateau=calcium; contraction
downstroke=potassium; relaxation
