What is a nasolacrimal duct?
The nasolacrimal duct is a tubular structure that drains tears from the eye's surface into the nasal cavity. It begins at the lacrimal sac, located at the inner corner of the eye, and extends down to open into the inferior meatus of the nasal cavity. This duct helps maintain tear drainage and prevents overflow, which can lead to tears spilling onto the face. Dysfunction or blockage of the nasolacrimal duct can result in conditions such as epiphora, where tears accumulate excessively.
What structure drains excess tears to the nasal cavity causing the nose to run?
The nasolacrimal duct is responsible for draining excess tears from the eyes to the nasal cavity, which can cause the nose to run. Tears are produced in the lacrimal glands and then flow across the surface of the eye to the corner of the eye, where the nasolacrimal duct is located. From there, tears drain into the nasal cavity, which can lead to a runny nose.
Which bone contains the nasolacrimal duct?
The nasolacrimal duct is found in the nasolacrimal canal and formed by the maxilla and lacrimal bone.
Are your tear ducts connected to your sinuses?
Yes, tear ducts are connected to the sinuses through a system of small passages. The tear ducts drain tears from the eyes into the nasal cavity, specifically through the nasolacrimal duct, which empties into the inferior nasal meatus. This connection is why your nose may run when you cry, as excess tears can flow into the nasal passages.

What empties into nasal cavity?
I'll assume you mean, how it gets from the nose to the lungs, rather than how it gets in the nose, as that should be obvious. Well if you breath really fast through your nose, especially with cold air you will feel it rush down this passage that is back in your throat where your food is swallowed, except it is up, of course. Then this goes the same way as air you breath through your mouth.
