Answer:

The liver stores vitamin A, D, E, K and B12. The first four of these are all fat soluble. This means that the bile secreted during digestion is essential for absorbing them so that the body can use them. If bile production is compromised by liver damage, the proper absorption of these vitamins may be affected.
