What is the Origin of Systemic Hemodynamics?

The term is derived from physiology and cardiology, combining the Greek words hemo (blood) and dynamics (power or force). In the context of hormonal health, it is essential because many hormones, such as thyroid hormones, cortisol, and sex steroids, exert profound regulatory effects on vascular tone and cardiac contractility. Changes in hormonal status often manifest clinically as alterations in hemodynamic parameters.

What is the Mechanism of Systemic Hemodynamics?

Hormones regulate hemodynamics through various mechanisms, including direct effects on the smooth muscle cells of blood vessel walls, modulating the release of vasoactive substances like nitric oxide, and altering fluid balance via the Renin-Angiotensin-Aldosterone System (RAAS

Systemic Hemodynamics

Meaning

This refers to the physical forces and physiological mechanisms involved in the circulation of blood throughout the entire vascular network, encompassing blood pressure, blood flow velocity, cardiac output, and peripheral vascular resistance. Optimal systemic hemodynamics ensure efficient delivery of oxygen, hormones, and nutrients to all tissues while effectively removing metabolic waste products. This is a critical component of cardiovascular health and is significantly influenced by endocrine factors.
