Resistance

Definition

In the context of the nervous system and blood flow, resistance refers to the opposition to blood flow in the blood vessels. It is influenced by factors such as vessel diameter, blood viscosity, and overall vessel length.

Related terms

Blood Viscosity: The thickness or stickiness of blood, which affects how easily it flows through vessels.

Vessel Diameter: The width of a blood vessel; smaller diameters create higher resistance to blood flow.

Blood Pressure: The force exerted by circulating blood on the walls of blood vessels, often influenced by resistance within those vessels
