Hemodynamic

/ˌhɛmoʊdaɪˈnæmɪk/ adjective

Definition

Relating to the physical forces and pressures involved in blood circulation and blood flow through the body.

Etymology

From Greek 'haima' (blood) and 'dynamis' (power/force). The adjective form emerged in medical science in the 19th century as physicians began studying blood circulation as a mechanical system.

Kelly Says

Hemodynamic is how doctors describe the 'physics of your heartbeat'—it's why your heart needs to pump harder when you exercise, and why blood pressure changes affect how your organs work!
