Turbulent flow is most likely to occur at high flow rates, where the inertial forces overcome the viscous forces.

Increasing the diameter of a blood vessel decreases resistance, thereby increasing blood flow according to Poiseuille's law.

Gravity affects fluid flow in the body, varying with body position; for example, it increases venous return when standing.

Red blood cells are the primary component that affects blood viscosity and flow properties.

Hydrostatic pressure is the primary driving force for fluid flow in the circulatory system, pushing blood through the vessels.

Laminar flow is characterized by fluid moving in parallel layers with minimal disruption between them.

Blood vessel length does not affect the viscosity of blood; viscosity is influenced by temperature, hematocrit level, and plasma protein concentration.

Poiseuille's law describes the relationship between pressure, volume, and flow rate in a fluid, particularly in laminar flow.

Dehydration can lead to increased blood viscosity due to a higher concentration of cells and proteins in the plasma.
