2. Blood Flow: The Lifeblood of the Body
The Vital Flow
Blood flow is the movement of blood through the circulatory
system. It delivers oxygen and nutrients to tissues and
(emoves
waste products.
The Heart's Pump
The heart is the primary pump of the circulatory system, It
contracts and relaices to propel blood throughout the body,

3. Microcirculation: The Small
Vessels, Big Impact
Microcirculation
Microcirculation refers to
the blood flow in the
smallest blood vessels -
arterioles, capillaries, and
venules.
Vital Role
Microcirculation is critical
for oxygen and nutrient
delivery
to cells and waste
removal, influencing tissue
health and function.

4. Traditional Blood Flow
Measurement Techniques
Ultrasound Doppler
Ultrasound Doppler measures
blood
flow velocity based on the
frequency shift
of renected sound
waves.
Thermal Dilution
Electromagnetic
Flowmetry
Electromagnetic flowmetry
measures blood
flow by detecting
the magnetic field induced by
blood
movement
Thermal dilution involves injecting a cold solution into the blood stream and
measuring the temperature change
to determine blood flow.
