Question

Where are the major arteries in your ears? If you puncture a major artery when you pierce your ear, will you die?

Answer 1

Hint: The arteries are blood vessels that deliver oxygenated blood from the heart to other tissues of our body. Artery is mainly a muscular tube lined by smooth tissue and has three layers: the inner layer lined by smooth tissue called endothelium.

Complete answer:
Our ear receives the majority of blood from a branch of the external carotid artery. Posterior auricular artery is an area posterior to the auricular structure.
The posterior auricular artery is mainly a muscular artery that emerges from the external carotid artery. This artery travels through the posterior region of our ear. It's main function is to connect the scalp and the ear.
Usually the arteries are deeply situated and are not exposed like the veins in our body. Therefore there are less chances that an artery gets damaged, while piercing the ear. As if it gets damaged the clotting system will immediately spring into action to prevent blood loss and the puncture injury due to piercing we get is also small.

Note:
The primary source of blood in our inner ear is the labyrinthine artery. The semicircular canals are supplied by the stylomastoid branch of the occipital artery or posterior auricular artery.
