Irene Gold Boards Part 1 - Physiology
Deoxygenated blood from the upper extremity goes to the: - correct answer Superior Vena
Cava
Deoxygenated blood from the lumbar goes to the: - correct answer Azygous vein then SVC
Deoxygenated blood from the lower extremity goes to the: - correct answer IVC
Isovolumeric relaxation= - correct answer Blood flowing into the atria
Isovolumeric contraction= - correct answer Blood is in the ventricles, valves are closed, builds
pressure in the ventricles
How much of blood passively flows from atrium to ventricle? - correct answer 80%
How much of blood is actively pushed through the atrium to ventricle via atrial contraction? -
correct answer 20%
What signals the atria to contract? - correct answer SA node
What is the pace maker of the heart? - correct answer SA node
Pulmonary arteries transport what kind of blood to the lungs? - correct answer Deoxygenated
Blood is oxygenated in the lungs due to what? - correct answer Bohr Effect
Pulmonary veins carry what kind of blood from the lungs to the left atrium? - correct answer
Oxygenated
What is stroke volume? - correct answer (End diastolic) - (end systolic)
What is cardiac output? - correct answer Stroke volume x heart rate
Diastole= - correct answer Relaxation
Systole= - correct answer Contraction
What is the 1st heart sound? - correct answer Closing of AV valves (tricuspid and bicuspid) —
Lub
What is the 2nd heart sound? - correct answer Closing of semilunar valves (pulmonic and
aortic) — Dub
What is the 3rd heart sound? - correct answer Ventricular gallop
What heart sound may indicate early signs of CHF in adults, but is normal in children and
athletes? - correct answer 3rd
What is the 4th heart sound? - correct answer Atrial gallop (cardiac pathology)
