A venule is a small blood vessel that collects blood from capillaries and merges to form larger veins. They play a crucial role in the circulation of deoxygenated blood back to the heart, serving as a conduit for the return of blood from tissues and organs. Venules also participate in the exchange of nutrients, waste products, and immune cells between the bloodstream and surrounding tissues.
