Microscopic visualization of nitric oxide facilitating communication between endothelial cells and smooth muscle cells in vessels.

Magnified view of nitric oxides role in regulating smooth muscle relaxation.

Most people still don’t realize this — nitric oxide can literally help you breathe. In hospitals, when patients face severe respiratory distress, inhaled nitric oxide is sometimes used to open up the airways and improve oxygen flow. It works by relaxing smooth muscles in the lungs and arteries, helping more air — and more life — reach the body. It’s a reminder of just how powerful this tiny molecule is. The same one our bodies produce every day can, in the right hands, save lives. #NitricOxide #
