D. Mucus
Correct Answer Is Option = Bile
Notes / Explanation
The largest gland in the human body, which also performs many vital functions, is the liver, and one of its important products is a digestive juice called bile. The liver is a large organ situated in the upper part of the abdomen, and it is remarkable for the enormous number and variety of tasks that it performs in maintaining the health of the body. Among its many functions, the liver produces bile, which is a fluid that plays an essential role in the digestion of food, particularly in the digestion of fats. After bile is produced by the liver, it is stored in a small sac and then released into the digestive system, where it helps to break down the fats in the food into smaller particles so that they can be more easily digested and absorbed by the body. Without bile, the body would find it very difficult to make proper use of the fats in the diet. However, the production of bile is only one of the many roles played by the liver. The liver also acts as a kind of chemical factory and storehouse for the body. It helps to process the nutrients absorbed from the food, converting them into forms that the body can use or store for later. It stores certain vitamins and other substances and releases them when they are needed. One of the most important functions of the liver is to act as a filter that removes harmful and poisonous substances from the blood, breaking them down into less harmful forms so that they can be removed from the body. The liver also helps in controlling the level of sugar in the blood, in producing substances that are needed for the clotting of blood, and in many other processes that are essential for life. Because of the great range of its functions, the liver is sometimes described as one of the hardest-working organs in the body. It also has a remarkable ability to repair and regenerate itself when part of it is damaged, which is unusual among the organs of the body. For PPSC and other competitive examinations, the key points to remember are that the liver is the largest gland in the human body, that it produces a digestive juice called bile which helps in the digestion of fats, and that it performs many other vital functions such as filtering harmful substances from the blood, storing nutrients and regulating blood sugar.
