Pronunciation: [ɐlˈɑː vˈe͡ɪn] (IPA) 
The alar vein is a blood vessel located in the nose. It is spelled with the phonetic transcription of /ˈælər veɪn/. The "a" in "alar" is pronounced like the "a" in "cat," while the "l" is pronounced with the tongue touching the roof of the mouth. The "v" in "vein" is pronounced with the bottom lip touching the top teeth, and the "e" sounds like the "a" in "place." The "i" in "vein" is pronounced like the "ee" in "sheep."
The alar vein is a term primarily used in anatomy and physiology to describe a specific vein found in the human body. It is part of the circulatory system and is located in the region of the nose.
The alar vein runs through the nasal cavity and serves as a drainage pathway for blood from the area. Specifically, it collects blood from the alar region, which refers to the sides of the nose. The alar vein is responsible for the transportation of deoxygenated blood, carrying waste materials and carbon dioxide, to the heart and lungs for purification and oxygenation.
In terms of its structure, the alar vein is a relatively small vessel compared to other major veins in the body. It is typically located beneath the surface of the skin, making it less visible to the naked eye. Its location within the nasal cavity provides it with vital protection and allows for efficient blood flow.
Understanding the alar vein's role in the circulatory system is crucial for medical professionals, as it can have implications for various health conditions related to the nasal region. Its proper functioning is paramount for normal blood circulation and overall well-being.

- "Vena" is the Latin word for "vein".
- "Alaris" derives from the Latin word "ala" meaning "wing".
The term "alar vein" is often used in anatomy to refer to a vein located within the wing of an insect or the wing-like structures of certain animals.
