Anastomosis
An anastomosis (plural anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams.

Artery
An artery (plural arteries) is a blood vessel that takes blood away from the heart to all parts of the body (tissues, lungs, etc).

Ethmoid sinus
The ethmoidal sinuses or ethmoidal air cells of the ethmoid bone are one of the four paired paranasal sinuses.

Frontal sinus
The frontal sinuses are situated behind the brow ridges.

Greater palatine artery
The greater palatine artery is a branch of the descending palatine artery (a terminal branch of the maxillary artery) and contributes to the blood supply of the hard palate and nasal septum.

Kiesselbach's plexus
Kiesselbach's plexus, which lies in Kiesselbach's area, Kiesselbach's triangle, or Little's area, is a region in the anteroinferior part of the nasal septum where four arteries anastomose to form a vascular plexus.

Maxillary artery
The maxillary artery supplies deep structures of the face.

Maxillary sinus
The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, and drains into the middle meatus of the nose.

Nasal meatus
A nasal meatus is a nasal passage of the nasal cavity, of which there are three; the superior meatus, middle meatus and inferior meatus.

Nasal septum
The nasal septum separates the left and right airways in the nose, dividing the two nostrils.

Nosebleed
A nosebleed, also known as epistaxis, is the common occurrence of bleeding from the nose.

Posterior lateral nasal arteries
The sphenopalatine artery passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus.

Posterior septal branches of sphenopalatine artery
Crossing the under surface of the sphenoid the sphenopalatine artery ends on the nasal septum as the posterior septal branches; these anastomose with the ethmoidal arteries and the septal branch of the superior labial; one branch descends in a groove on the vomer to the incisive canal and anastomoses with the descending palatine artery.

Sphenoidal sinus
Each of the paired sphenoidal sinuses (components of the paranasal sinuses) is contained within the body of the sphenoid.

Sphenopalatine foramen
The sphenopalatine foramen is a foramen in the skull that connects the nasal cavity with the pterygopalatine fossa.
