Which of the following is needed to digest fats?

A. Inflammation: inflammation causes vasodilation and increased capillary permeability so immune cells and plasma components reach the injured/infected tissue.
B. Activation of NK cells: NK cell activation is an innate cytotoxic response against infected or malignant cells but does not itself describe the vascular changes listed.
C. Complement activation: complement promotes opsonization, chemotaxis, and membrane attack, but the described vasodilation/permeability hallmark is inflammation.
D. Activation of mononuclear phagocytic system: activation of macrophages/monocytes contributes to defense and cleanup, but the vascular response described is specifically the inflammatory process.

A. Production of bile: the liver synthesizes and secretes bile (stored in the gallbladder).
B. Detoxification of toxins: the liver metabolizes and detoxifies many endogenous and exogenous compounds.
C. Production of glycogen: the liver synthesizes and stores glycogen (glycogenesis) to regulate blood glucose.
D. Digestion of nucleic acids: nucleic acid digestion is performed by pancreatic and intestinal enzymes in the small intestine, not by the liver.
