Which statement is true about the greater omentum?

The greater omentum is a significant fold of peritoneum that hangs down from the greater curvature of the stomach and covers the intestines. It is indeed composed of four layers of peritoneum because it originates from the dorsal mesentery during development. The four layers provide a protective covering and also contain fat and immune cells, which contribute to the body's defense mechanisms. This structure plays an essential role in fat storage, immune responses, and even in insulative functions, but it is not designed primarily for nutrient absorption, which occurs in the intestines. Understanding the composition and function of the greater omentum helps clarify its importance in both anatomy and physiology, especially concerning the abdominal cavity's organization and the body's immune defense strategies.
