The simple answer is 'they do.'
If you were to hold a piece of paper up to direct sunlight, you would be able to the sunlight coming through the paper. The paper is opaque but not completely so, some light does get through. If you were to put a piece of glass on top of this piece of paper you would see it too. Even though glass is transparent to visible light it still has refractive and reflective properties that effect the light that falls on it.
The same is true for x-rays. Flesh and bone is opaque to x-rays but not completely so. Shining x-rays on a limb will show something of the things in it.
No, the human body is not transparent to the visible spectrum of light. Skin, muscles, and other tissues in the body absorb and scatter visible light, which is why we cannot see through the human body like we can with glass.
Its temperature increases. It continues to radiate a spectrum of light ("black body") representative of its new higher temperature. At some level of current, we see it as a source of visible light.
Yes, a glass of water can transmit visible light. Water is a transparent substance, meaning that light can pass through it without being scattered. The amount of light transmitted through the water may vary depending on its clarity and any impurities present.
Yes, the human body does produce light, although it is extremely faint and not visible to the human eye. This light is known as biophotons and is generated as a byproduct of biochemical reactions that occur within the cells of our bodies.

A female guppy has a darker brown line that is visible through its body. The male has a very light brown line.
Because x-rays - as opposed to visible light - can go through fairly thick parts of the body. Useful if you suspect a broken bone for instance. Visible light will only go through thin parts of your body, like cheeks, earlobes. And will only give a reddish blur at that. Not particularly useful to find out what's going on inside.
The only light that travels through the body is the image seen by the retina at the back of the eyeball. It travels through the lens and is inverted. This is sent by the optical nerve to the brain where it is turned right side up again.
it travels through your body because it does.
On average, it takes about 20-30 seconds for blood to travel through your body.
Yes, photons of light can pass through our bodies. Photons interact with atoms in our body, but most of the time they pass through without being absorbed or scattered, allowing them to travel through us. This is why we can see light and feel warm sunlight on our skin.
Its temperature increases. It continues to radiate a spectrum of light ("black body") representative of its new higher temperature. At some level of current, we see it as a source of visible light.
Alpha radiation, it's force is too weak to even penetrate the outer layer of dead skin. Beta and Gamma radiation can pass through, Beta has trouble passing through clothes whereas Gamma is able to go straight through the body.
Assuming you mean through the victim's body - it travels through the bloodstream.
A red blood cell takes about 20 seconds to travel through the body.
X-rays are a form of electromagnetic radiation, like light waves, but they have a much shorter wavelength and higher energy than visible light. This allows them to penetrate through tissues and create detailed images of the inside of the body.
