Digestive System

Master the digestive system! Label diagrams, match functions, and explore disorders with our engaging worksheet.

use the word bank below to label the diagram;enamel, cementum,gum, blood vessels and nerves, dentine enamel dentine gum blood vessels and nerves cementum, The figure above shows the organs of the digestive system (labeled A-F). Match each organ to its function. relies on peristalsis to move food to the stomach E produces bile A mechanical and chemical digestion begins here D hydrochloric acid is released to promote digestion of proteins F releases bile into the duodenum B secretes bicarbonate and digestive enzymes into the small intestine C Match each of the following disorders associated with the digestive system to its description. inability to digest milk sugar due to lack of an enzyme; symptoms include bloating, abdominal cramps, and diarrhea lactose intolerance Heartburn is a burning feeling in the chest caused by stomach acid travelling up towards the throat reflux inflammation of the lining of the stomach. gastritis open sores that develop on the lining of the stomach or duodenum ulcer are swollen veins in the lowest part of your rectum and anus hemorrhoids refers to bowel movements that are infrequent or hard to pass. constipation is loose and watery stool during a bowel movement diarrhea The process by which food is propelled through the digestive tract by alternating contraction and relaxation of smooth muscle is: elimination. secretion. chemical digestion. peristalsis. absorption. Which major digestive process involves nutrient molecules passing across the mucosal layer of the gastrointestinal tract into the blood or lymph? elimination absorption digestion secretion mechanical processing and movement During swallowing, the epiglottis bends to close the trachea. smooth muscle in the esophagus contracts slightly. the tongue flattens to the bottom of the mouth. salivary secretions stop. the hard palate rises to close the nasal passages Which one of the following components of saliva has antibacterial properties? sodium bicarbonate amylase mucin lysozyme HCl Gastric juice in the stomach is composed of; HCL, fluids secreted from gastric glands, pepsinogen. chyme, HCL, mucus. HCL, secretin, saliva. pepsinogen, secretin, gastrin fluids from gastric glands only. The watery mixture of partially digested food produced in the stomach is called bolus. chyme. segmentation. dentin. mucin Pepsin is a digestive enzyme that specifically targets fatty acids. steroids. starch. glycogen. protein. Nutrient-rich blood moves from the small intestine to the liver via the pancreatic duct. lacteal vessels. the pulmonary circuit. the hepatic portal system arterial flow from the gastrointestinal tract to the liver Bile assists in the chemical digestion of triglycerides by hydrolyzing them to glycerol and fatty acids. emulsifying large fat droplets into tiny ones, providing more surface area for enzymes. breaking peptide bonds and hydrolyzing them to amino acids forming chylomicrons. assisting with the active transport of triglycerides into the blood. All of the following are involved in the digestion of proteins EXCEPT which one? pepsin amylase carboxypeptidase chymotrypsin trypsin Bacteria residing in the large intestine release vitamin K which is absorbed by the human host and used for the process of blood clotting. true false Gastrin is a hormone secreted by the stomach true false Secretin modulates digestion by acting as an enzyme in the duodenum triggering bile release into the intestine. triggering buffer release from the pancreas. acting as an enzyme in the stomach. triggering acid release in the stomach In which of the following structures does absorption of water, vitamin K, and salt occur? large intestine small intestine liver stomach pancreas fill in the table below with the correct information about carbohydrates digestion enzymes for carbohydrates digestion source where active salivary amylase salivary glands mouth pancreatic amylase pancreas small intestine intestinal enzymes(Disaccharidase) small intestine small intestine
