How is ruminants stomach different from human stomach?

Human stomach cannot digest fatty acids while ruminant stomach can digest them.

Explanation:

There are certain fatty acids which can be absorbed directly through ruminal wall into blood stream which usually fulfills 60 to 80 % of energy needs of Ruminants. On the other hand human stomach can not break down cellulose and derive no energy from it. So we can say that Ruminants stomach can digest fatty acids while human stomach cannot break down these cellulose.
