where does the blood come from during a nosebleed
Nosebleed
The vast majority of nose bleeds occur in the anterior ( front ) part of the nose from the nasal septum . This area is richly endowed with blood vessels ( Kiesselbach 's plexus ) . This region is also known as Little 's area . Bleeding farther back in the nose is known as a posterior bleed and is usually due to bleeding from Woodruff 's plexus , a venous plexus situated in the posterior part of inferior meatus . Posterior bleeds are often prolonged and difficult to control . They can be associated with bleeding from both nostrils and with a greater flow of blood into the mouth .
