Healthy volunteers (ages 18-40) needed for muscle blood flow research study.

“Exploring microcirculatory control in humans”

The University of North Texas Health Science Center and the Human Vascular
Physiology Laboratory are currently recruiting volunteers (ages 18-40) to examine if
small passageways located on the surface of blood vessels contribute to blood vessel
dilation in skeletal muscle of humans. We are recruiting men and women to take part in
this research study.

Study Requirements:
• Visit Human Vascular Physiology Laboratory at UNTHSC for testing on 2 separate
days; the first will be 1-2 hours, the second will be approximately 5 hours, for a total
study time commitment of ~7 hours.

• Participation in this study is voluntary, and if you are a student or employee of
