Inside Your Arm: 5 Surprising Parts That Actually Help Move Blood — Find Out Now! Ever wonder what’s really happening inside your arm when blood flows through it? While veins and arteries get most of the spotlight, your arm contains several underappreciated structures that play vital roles in blood circulation — and blood movement in particular. Today, we’re peeling back the skin to explore 5 parts you never knew were actively moving blood inside your arm. From hidden valves to supporting connective tissues, here’s what really keeps your blood flowing smoothly — and how understanding these parts can change how you think about vascular health. --- ### 1.

Understanding this network helps explain why compression garments are so effective at boosting circulation in the arm.
