The emulsion on the film of a camera is where the image is focused and captured. In the eye that function is performed by the retina.
its called cornea of eye

The iris.
The eyelid.

The shutter.
shutter speed
it is a device that is part another device mostly a camera that makes a shutter sound to tell you that the picture is taken
the shutter speed is how fast the shutter can go eg. an dslr has a faster shutter speed than a digital camera the shutter is a part on the camera that opens and closes when it opens it draws the light from the object focused on and places it on the lcd screen of film giving you your pic

The Shutter.
As in a camera, this part is usually called an iris diaphragm. It can make the aperture bigger to let in more light, or smaller to make the image sharper. The shutter in a camera is not the same thing.
If the camera has a "shutter priority mode", usually called "S mode", then the shutter speed is controlled directly by the user when the camera is in this mode, by moving a dial or pressing a button (or both). If the camera has a "manual" mode, usually called "M mode", then the shutter speed and aperture are both controlled directly by the user by moving dials or pressing buttons (or both). Some cameras have automatic modes which allow the user to control the minimum and maximum shutter speeds that will be selected by the camera when considering all other factors. If the minimum shutter speed is reached, the camera will increase the ISO or aperture size to compensate for under-exposure. If the maximum shutter speed is reached, the camera will decrease the ISO or aperture size to compensate for over-exposure.

The shutter is a piece of the camera that opens up when you take a photo. The shutter speed is how long this shutter stays open, the longer the time , the more light getting through - and the more motion blur. The aperture is the part of the camera that controls how much light is getting through, the smaller the f stop the more light getting through, and vice versa. The aperture is like the black part of are eye, I do not know if you have ever noticed, but, when you go in to a dark place the black dot gets bigger, when you go to a place with a lot of light the black dot gets smaller, same for the camera. Also, you did not mention ISO, that is not a part of the camera but just a setting. The higher the ISO the more sensitive the shutter is to light, but you also get more noise with high ISO.
