Though bile juice is devoid of any digestive enzymes, it is required for the digestion of fats. The fats cannot be digested easily because they are insoluble in water and are present as large globules. Bile juice breaks down big fat droplets into smaller droplets.

The food will not be digested..
First of all the food particles will not be broken into simpiler substances.

Introduction:
The human digestive system is a complex network of organs that work together to break down food and absorb nutrients. Two important components of this system are bile juice and saliva. Bile juice is produced in the liver and stored in the gallbladder, while saliva is produced in the salivary glands. Both these substances play crucial roles in the digestion process. If bile juice and saliva are not secreted in the human digestive system, it can lead to various negative consequences.

Effects of Bile Juice Absence:
1. Impaired Fat Digestion: Bile juice is essential for the digestion and absorption of fats. It emulsifies the fats, breaking them into smaller droplets, which increases the surface area for enzymes to act upon. Without bile juice, the digestion of fats would be compromised, leading to reduced absorption of fat-soluble vitamins and essential fatty acids.

2. Nutrient Deficiencies: Bile juice also aids in the absorption of fat-soluble vitamins, such as vitamins A, D, E, and K. Without bile juice, the absorption of these vitamins would be impaired, potentially leading to nutrient deficiencies and related health issues.

3. Gallbladder Complications: The gallbladder stores and releases bile juice as needed. If bile juice is not secreted, the gallbladder may become stagnant, leading to the formation of gallstones or inflammation of the gallbladder (cholecystitis).

Effects of Saliva Absence:
1. Impaired Digestion: Saliva contains enzymes, such as amylase, that initiate the breakdown of carbohydrates. Without saliva, the initial digestion of carbohydrates would be compromised, making it more challenging for the subsequent digestive processes to occur efficiently.

2. Dry Mouth and Difficulty Swallowing: Saliva also helps moisten the mouth, lubricate food for easy swallowing, and maintain oral hygiene by washing away bacteria. The absence of saliva can result in a dry mouth, making it uncomfortable to eat and speak. It may also lead to difficulties in swallowing food.

3. Dental Problems: Saliva plays a crucial role in maintaining oral health by neutralizing acids produced by bacteria, preventing tooth decay, and remineralizing tooth enamel. In the absence of saliva, dental problems such as tooth decay, gum disease, and bad breath may occur more frequently.

Overall Impact:
The absence of bile juice and saliva in the human digestive system can have significant negative consequences on digestion, nutrient absorption, and oral health. It can lead to impaired fat digestion, nutrient deficiencies, gallbladder complications, impaired carbohydrate digestion, dry mouth, difficulty swallowing, and dental problems. Therefore, the secretion of bile juice and saliva is essential for maintaining a healthy digestive system and overall well-being.
