Produces essential proteins and clotting factors for the blood and regulates metabolism and cholesterol. Gall Bladder – Stores bile secreted by liver. Bile is used to help dissolve fats in the small intestine. Pancreas – Functions both as an exocrine gland and an endocrine gland. Exocrine portion secretes digestive enzymes carried to the duodenum.
This amylase converts the remaining starch into maltose. Maltose and lactose are absorbed into the small intestine. Multiple enzymes reside in the microvilli that lines the small intestine: maltase, lactase and sucrose. They’re called brush border enzymes The brush border enzymes convert the disaccharides into monosaccharides: glucose, fructose, and galactose. The monosaccharides are them absorbed into the bloodstream.
Secretes pancreatic juice, insulin, glucagon, duodenum, and somatostatin into the bloodstream. Regulates blood sugar and completes the breakdown of protein, carbohydrates and fats 17. Responsible for the production and maintenance of the protective mucous blanket by synthesizing and secreting glycoproteins known as mucins. 18. Stores and concentrates bile 19.
d. Zach’s G.I. tract needs the substance to assist in the breakdown of food and for absorption. Epithelial cells extend into the lamina where they form secretory folds called gastric glands. Several of these glands open into the gastric pits and secretions from these glands flow into the pits. E. If Zach’s only normal digestive enzymes from his mouth, what
The lymph ascends or descends to the left or right lymphatic duct. f. Describe the lymphatic system role with regard to lipids and lipid-soluble vitamins. The lymphatic system supports the lipids and vitamin A,D,E,K from the GI tract blood stream initiates specific immune responses. 3. What are the thymus gland functions?
_____ Trypsin digests complex carbohydrates to simple carbohydrates. 42. _____ Glycogen and starch are polysaccharides of glucose and both are stored in liver and muscle. 43. _____ The pancreas produces both insulin and glucagon.
A2: 1. Mouth: The mouth starts mechanical digestion with the chewing that takes places there but also mixes amylase that is secreted from the salivary glands in with what is being chewed to start chemical digestion. (2) 2. Esophagus: The esophagus transfers food from the mouth to the stomach. (2) 3.
Absorption of nutrients occurs mainly from the a) liver b) colon c) stomach d) small intestine 15. Prolactin is produced by the a) ovary b) adrenal gland c) anterior pituitary gland d) posterior pituitary gland 22. The beta cells of the Islets of Langerhans secrete a) insulin b) amylase c) glucagon d) histamine 16. Dyspnoea is breathing that is a) fast b) noisy c) shallow d) difficult 23. 17.
CU2653 Prepare For and Carry Out Extended Feeding Techniques 1.1Anatomy and physiology of the gastro-intestinal tract: Digestion of food begins in the mouth. When you swallow, food is pushed down into the oesophagus, a muscular tube that carries food to the stomach where it is digested. From the stomach, food travels to the small intestines, where digestion continues and nutrients are absorbed into the bloodstream. 1.2 The importance of fluid and nutritional balance: Eating food provides you with nutrients that are necessary for your body to function, grow, and repair its self. We need to consume six types of nutrients to sustain life: carbohydrates, protein and fat, which all provide energy, but in different forms, vitamins and minerals,
Depending on how much food is consumed, the chyme will partially digest in the stomach and will empty out in approximately two to six hours. Once processed by the stomach, the chyme enters the small intestines. Secretions of bile come from the liver and the gallbladder (a storage place for the bile that is produced by the liver) to absorb all the vitamins, proteins, minerals, carbohydrates, and fats from the food. On the other hand, the pancreas aids the process of digestion by sending digestive enzymes to the small intestines. The left over waste, from the small intestines, transfers through the sphincter and into the large intestine.
