The cervical vertebrae (C1-C7) are part of the spinal column and the spinal cord passes through them.
Vertebral artery passes through transverse formamina of C1-C6!
Sinus cavity
A bolus (of food, for instance) passes through the esophagus.
The trachea is the airway that passes through the mediastinum anterior to the esophagus. It is a tube-like structure that carries air to and from the lungs, and is situated in front of the esophagus in the chest cavity.
When light enters the eye, it first passes through the cornea, which is the transparent outer layer of the eye. The cornea helps to focus the light as it enters, before it passes through the aqueous humor and then the pupil, which is controlled by the iris to regulate the amount of light that continues into the eye.

It is called conduction when electricity passes through a metal due to the movement of free electrons within the metal's structure.
A bolus (of food, for instance) passes through the esophagus.
The structure in the eye through which light passes to allow you to see an image is the lens. The lens in the eye helps focus light onto the retina at the back of the eye, where the image is formed and sent to the brain for processing.
No, not all objects are opaque. Some objects are transparent (light passes through easily), translucent (light passes through but is diffused), or opaque (blocks light from passing through). It depends on the material and structure of the object.
