Physiology 300: Hemodynamics, Cardiac
Function, and Blood Pressure Exam
Questions and Answers with Verified
Solutions | Latest Updated 2026
What is Hemodynamics? The physics of blood flow, explaining how
pressure, resistance, and vessel diameter
determine blood movement.
What is the pathway of pulmonary Heart → Lungs → Heart (Right atrium →
circulation? right
ventricle → pulmonary arteries → lungs →
pulmonary veins → left atrium)
What are the characteristics of Low pressure and low resistance to protect
pulmonary circulation? delicate lung capillaries.
What is the purpose of systemic To deliver oxygen and nutrients to the
circulation? body and
return carbon dioxide and waste to the
heart.
What is the pathway of systemic Heart → Body → Heart (Left ventricle →
circulation? aorta →
arteries → capillaries → veins → right
atrium)
, What are the characteristics of High pressure and high resistance to
systemic circulation? ensure blood
reaches distant organs.
What is the function of arteries? To carry blood away from the heart,
characterized
by thick muscular walls and high pressure.
Why are arterioles considered Small changes in their radius dramatically
resistance vessels? change
resistance, controlling blood distribution
and
blood pressure.
What is the function of capillaries? To facilitate the exchange of oxygen,
nutrients, and
wastes due to their extremely thin walls.
What is the composition of blood The liquid portion of blood (~55%),
plasma? containing
water, proteins, hormones, nutrients, and
electrolytes.
What is the function of To transport oxygen using hemoglobin,
erythrocytes? with more
RBCs increasing blood viscosity.
What is the function of leukocytes? To provide immune defense against
bacteria,
viruses, and pathogens.
