Nutrition, Vitamins & Digestion Questions with Solutions
This topic covers human nutrition: carbohydrates, proteins, fats, vitamins and minerals, their sources and the diseases caused by their deficiency, balanced diet, and the human digestive system with its organs, glands and enzymes.

The liver is the largest gland in the human body and produces bile.
