Answer

It starts in mouth ...an enzyme called salivary amylase or ptaylin starts digesting carbohydrates in mouth

Answer

As in mouth saliva or salivary amylase breaks down complex sugar into simple one so digestion start from mouth.

Answer

The process of digestion of food starts in the mouth.
- The mouth is the first organ involved in the process of digestion.
- It contains several structures that aid in the breakdown of food.
- The teeth are responsible for chewing and breaking down food into smaller pieces, increasing the surface area for digestion.
- The tongue helps in manipulating the food and mixing it with saliva.
- Saliva, produced by the salivary glands, contains enzymes that begin the digestion of carbohydrates.
- These enzymes, such as amylase, break down complex carbohydrates into simpler sugars.
- The food is then formed into a ball called a bolus and is swallowed, entering the food canal or the esophagus.
- From the esophagus, the bolus moves down into the stomach.
- In the stomach, the process of digestion continues with the release of gastric juices.
- These juices contain enzymes and acids that break down proteins and kill bacteria present in the food.
- The partially digested food, now called chyme, moves into the small intestine for further digestion and absorption of nutrients.
In conclusion, the process of digestion starts in the mouth where food is broken down into smaller pieces and mixed with saliva containing enzymes. Therefore, the correct answer is C: Mouth.
