The carotid artery is a major blood vessel in your neck that supplies blood to your brain, face, and scalp 🧠. Think of it as the highway for blood, delivering essential oxygen to your head. There are two carotid arteries: one on the left and one on the right side of your neck. They branch off from the aorta and split into internal and external carotid arteries. Without these arteries, your brain wouldn't get the oxygen it needs, like a car without fuel ⛽. They are critical for life.
