vascular resistance

Vascular resistance refers to how much the blood vessels resist the flow of blood. Imagine the blood vessels as pipes carrying water; if the pipes are narrow or clogged, it’s harder for water to flow through, increasing resistance. In the body, blood vessels can expand or constrict, affecting how easily blood flows. High vascular resistance can lead to higher blood pressure, while low resistance makes it easier for blood to circulate. It’s a key factor in understanding how the heart and blood vessels work together to deliver oxygen and nutrients throughout the body.
