The parotid glands contribute a serous fluid rich in amylase amylase is a digestive enzyme that begins carbohydrate digestion the submandibular glands secrete a primarily serous fluid that also contains some mucus mucus secreted from the sublingual glands helps bind food together and acts as a lubricant during swallowing as food is swallowed it enters the esophagus
And is moved downward by a wave-like muscular contraction called peristalsis the contractions progress from the superior end of the esophagus to the gastroesophageal junction where the contents of the esophagus empty into the cardiac region of the stomach the lining of the stomach secretes gastric juices that contain digestive enzymes peristalsis churns and mixes the
Food with gastric juices while moving the food toward the first part of the small intestine the duodenum in the duodenum food is digested even further the bile duct from the liver and gallbladder and the pancreatic duct from the pancreas all empty their secretions in the duodenum the bile works to break down fats while the pancreatic enzymes aid in the digestion of
Other food particles together these digestive juices help prepare the food so that the small intestine can absorb as many nutrients from the food as possible the majority of the absorption takes place in the second portion of the small intestine a three-foot section called the jejunum as the food travels through the jejunum it’s gradually broken down into smaller
And smaller particles folds line the walls of the intestine and act to increase the absorptive surface area the green nutrient particles and the yellow fat particles get caught in these folds and are absorbed into the intestinal wall larger less digested particles are pushed on to the large intestine where much of the water they contain is reabsorbed before being
Expelled from the body a closer inspection of the folds reveals that the intestinal wall is covered with thousands of finger-like villi a network of tiny blood vessels called capillaries runs just below the surface of each villus these capillaries absorb the available nutrients in the intestine and transport them to the liver the yellow fat nutrients are absorbed
Into a vessel called a lacteal that carries them to the circulatory system nutrients absorbed by the blood in the villi are carried to the liver by way of the portal vein in the liver the blood is filtered and the nutrients are extracted and processed after processing the nutrients are either stored for future use or released into the bloodstream to be used throughout the body you
