Arteries carry oxygenated blood away from your heart. They have thick walls and a muscular layer that keeps your blood moving. Arteries can be as wide as a nickel (about two centimeters). They are the ...

Engineered human capillaries are providing an astounding view of how red blood cells transit ultra-small blood vessels. This new platform was used in a recent study to learn how severe malaria ...

The kidneys contain millions of microscopic blood vessels known as peritubular capillaries. These vessels recapture helpful nutrients like glucose and minerals and return them to your bloodstream for ...
