Medsci 142: Cardiovascular Exam Questions
With Correct Answers
Pulmonary circuit - answer✔Part of cardiovascular system between RA and RV and LV and LA
via the lungs. Smaller circuit of medium pressure and low blood volume (9%)
Systemic circuit - answer✔Part of cardiovascular system between LV and LA and RA and RV
via various body systems including the gut, liver, kidneys, brain and limbs. Large circuit of high
blood volume (84%) and high pressure
Artery - answer✔A vessel which takes blood away from the heart
Vein - answer✔A vessel which takes bloody towards the heart
Portal vein - answer✔A vessel which takes blood from a system to another system
Dual supply - answer✔When a system is supplied by two major vessels eg: liver being supplied
by hepatic portal vein from gut and hepatic artery from heart.
Ventricle - answer✔Bottom chambers of the heart: strong and able to generate high pressure.
Receive blood from the atrium and pump blood through pulmonary and systemic circuit via the
pulmonary trunk and aorta respectively

Atrium - answer✔Superior chambers of the heart, receive blood from veins (Vena Cava and
pulmonary) and pump blood to the ventricles. Pump at low pressure.
Filling phase - answer✔Blood flows into the ventricle
Ejection phase - answer✔Blood flows out of the ventricle
Auricle - answer✔Appendage attached to the atria in order to increase their capacity.
Vena cava - answer✔Veins bringing blood to the right atrium from the systemic circuit.
Comprised of superior and inferior
Pulmonary trunk - answer✔Large vessel carrying blood from right ventricle to the lungs. Splits
into left and right pulmonary arteries
Inter-ventricular sulcus - answer✔Groove which separates the ventricle externally. Runs both
anteriorly and superiorly
Aorta - answer✔Large vessel carrying blood away from the left ventricle into the systemic
circuit
Peak pressures - answer✔The maximum pressure generated by each chamber of the heart. For
RA,RV,LA,LV these are 5,27,8 and 120 mmHg respectively
Tricuspid valve - answer✔Valve of three flaps between the RA and RV to stop blood flow back
into the RA when the RV contracts
