What happens to chyme in the small intestine during the process of digestion?
In the small intestine, chyme is further broken down by enzymes and absorbed into the bloodstream for nutrients to be used by the body.
What is the oval organ that sends fluid into the small intestine to chemically digest and neutralize chyme?
The pancreas is the oval organ that sends fluids, such as enzymes and bicarbonate, into the small intestine to aid in the chemical digestion and neutralization of chyme.
What controls the amount of chyme entering that small intestine?
The pyloric sphincter controls the amount of chyme entering the small intestine from the stomach. It regulates the flow of partially digested food to ensure that it is properly mixed with digestive enzymes and bile for further digestion. This helps to maintain optimal conditions for nutrient absorption in the small intestine.
What digestive substances does the small intestine secrete?
The small intestine secretes enzymes such as amylase, lipase, and protease to break down carbohydrates, fats, and proteins, respectively. It also produces bicarbonate to help neutralize the acidic chyme from the stomach. Additionally, the small intestine releases mucus to protect its lining and facilitate the movement of food.
What do fats in chyme stimulate the secretion of?
Fats in chyme stimulate the secretion of bile from the gallbladder and enzymes from the pancreas to help with fat digestion and absorption in the small intestine.

What watery liquid moves from the stomach to the small intestine?
The watery liquid that moves from the stomach to the small intestine is called chyme. Chyme is a mixture of partially digested food, stomach acid, and enzymes that is produced in the stomach to aid in digestion and absorption of nutrients in the small intestine.

This helps to maintain optimal conditions for nutrient absorption in the small intestine.
Where is the chyme located?
Chyme is located in the small intestine, specifically after it has passed through the pyloric sphincter from the stomach. It is a semi-liquid mixture of partially digested food, gastric juices, and digestive enzymes. The presence of chyme in the small intestine initiates further digestion and nutrient absorption.
Why doesn't the small intestine contain the acid chyme?
The duodenum is the main site for digestion in the small intestine. Here, more enzymes are added to the chyme, some of which come from the intestinal wall and others from the pancreas. The pancreas is one of the major glands of the body, and has two functions: releasing digestive enzymes into the gut, and releasing hormones into the blood. Pancreatic juice also contains sodium bicarbonate, which neutralizes the acid chyme arriving in the duodenum, and provides an alkaline environment for optimum functioning of pancreatic and intestinal enzymes. These enzymes include proteases to continue protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Enzymes in the intestinal juice generally start off the later stages of digestion.

Fats in chyme stimulate the secretion of bile from the gallbladder and enzymes from the pancreas to help with fat digestion and absorption in the small intestine.
What happens when the juices from the pancreas are mixed with the chyme in the upper part of the small intestine?
When pancreatic juices mix with chyme in the upper part of the small intestine, they contribute critical digestive enzymes and bicarbonate. The enzymes, such as amylase, lipase, and proteases, help break down carbohydrates, fats, and proteins into their smaller components. The bicarbonate neutralizes the acidic chyme from the stomach, creating a more alkaline environment optimal for enzyme activity and further digestion. This process is essential for nutrient absorption as the chyme progresses through the small intestine.
What changes the pH of chyme as it enters the duodenum?
The duodenum releases bicarbonate-rich pancreatic juice to neutralize the acidic chyme coming from the stomach. This helps raise the pH of the chyme in preparation for digestion by enzymes in the small intestine.
Does chyme enter the small intestine on the right or the left?
Chyme enters the small intestine from the stomach on the right side, known as the pyloric sphincter. Once in the small intestine, chyme is further broken down and nutrients are absorbed into the body.
Where does the chyme go?
Chyme is the partially digested food mixture that passes from the stomach to the small intestine for further digestion and absorption of nutrients. From the small intestine, the remains of the chyme continue through the large intestine where water is absorbed and waste products are formed before being excreted from the body.
