Cardiovascular System Hemodynamics
(Test:4) Exam Actual Questions and
Answers 2026
Review of Hemodynamics -
correct answer ✅1.Hemodynamics: the principle of blood flow, the
physical principles governing pressure, flow, and resistance.
2.HIGH to LOWER pressure: The arteries and arterioles provide the
high pressure end of the gradient.
-BLOOD MOVES ALONG TOWARD THE VEINS ( a lower pressure
system)
-THE GREATER THE PRESSURE DIFFERENCE THE FASTER THE BLOOD
FLOW
Components of the circulatory system
Blood Vein/Vessel Lining -
correct answer ✅"Tunicae"
-Intima(Inner most layer)
Lined with endothelial cells that provide a smooth slippery surface
for blood cells to glide over.
-Media- Smooth muscle layer
,Cardiovascular System Hemodynamics
(Test:4) Exam Actual Questions and
Answers 2026
Controls the diameter of a vessel(Middle Layer/Thickist)
-Externa - Fibrous connective tissue
"Athro"Sclerosis:
vs "Arteriol"Sclerosis -
correct answer ✅"Athro"Sclerosis: Attacks the BIG VESSELS
"Arteriol"Sclerosis: Attacks the LITTLE VESSELS in your Peripherally.
Overview of the Circulatory System: -
correct answer ✅1.Distribution of blood
-9% in the pulmonary circulation (LUNGS)
-7% in the heart
-84% in the systemic circulation
-Force that drives flow is greater than resistance
How does blood get back to the heart?

What makes blood flow -
correct answer ✅1.HIGH to LOWER pressure: The arteries and
arterioles provide the high pressure end of the gradient.
-BLOOD MOVES ALONG TOWARD THE VEINS ( a lower pressure
system)
-THE GREATER THE PRESSURE DIFFERENCE THE FASTER THE BLOOD
FLOW
Resistance:
1. Vessel Diameter
2. Vessel Length
3. Blood Viscosity
TPR: The total peripheral resistance that the blood encounters as it
flows through the systemic circulation
Factors Affecting Resistance -
correct answer ✅1.Vessel Radius
-Plaques & clots
-WHERE DOES THIS COME FROM?
