Quiz Questions
Question 1: What is the function of the salivary glands?
The salivary glands produce saliva, which helps to break down food and make it easier to swallow. Saliva also contains enzymes that start the digestion of carbohydrates.
Question 2: What is the function of the stomach?
The stomach is a muscular sac that churns and mixes food with stomach acid and enzymes to break it down further. It also helps to kill any harmful bacteria that may be present in food.
Question 3: What is the function of the small intestine?
The small intestine is where most of the nutrients from food are absorbed into the bloodstream. It is lined with tiny finger-like projections called villi, which increase the surface area for absorption.
Question 4: What is the function of the large intestine?
The large intestine absorbs water and electrolytes from the remaining indigestible food matter, forming feces. It also houses bacteria that help to break down some of the remaining nutrients.
Question 5: What is the function of the rectum and anus?
The rectum and anus are the final parts of the digestive system. The rectum stores feces until it is ready to be eliminated, and the anus is the opening through which feces are expelled from the body.
