The are independent and can work together. Pretend the lens is your eyes. How open and closing your eyes(lens) is the shutter function. Open them fast you let in less light, do it slow and you let in more light
Aperture is how wide you open your eyes(lens). Open them wide, you let in more light and blur the background. Open them narrow, you let in less light, but get a sharper image with more depth of field in focus.

They are directly or inversely related.
They both have to do with the amount of light coming into the camera.
As you increase the shutter speed, you need to open up the aperture more.
A faster shutter speed means less light is getting into the camera, so in order to let more light into the camera, you need to open up the aperture (lower the f-number).
Looking at it from the aperture side. As you close down the aperture (the f-number gets higher), you are letting in less light, so you have to compensate by slowing down your shutter speed.

Shutter speed affects aperture only if you are using one of the "auto" modes. In Manual mode, you are in full control and shutter speed and aperture are completely independent.
In "auto" modes, ... do some research man... here's a good, easy to understand, tutorial on the subject

They are independent functions, unless you have a camera that automatically changes aperture when you change the shutter speed.
In that case, if you move to a lower shutter speed, the aperture will close down more... which will allow more "depth of Field" (more things in focus)

International Standards Organization
Mechanical Aperture, Shutter Speed, and ISO
Change one and you must change another to maintain the same exposure!
One standard aperture permits one-half or double the amount of light to enter the camera. Aperture f5.6 permits double the light to enter that f8 permits. And f8 permits half the light to enter that f5.6 permits. Of course, a 1/250th of second shutter speed is half the time of 125th of a second, and 125th of a second is twice the time of 1/250th.
