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.
_____ Glucagon acts by raising blood sugar levels; insulin acts by lowering blood sugar levels. 46. _____ Secretin is released by the small intestine due to the presence of acid and leads to bicarbonate release from the gall bladder. 47. _____ CCK is released by the stomach due to the presence of fats and leads to bile release from the pancreas.
Exocrine portion secretes digestive enzymes carried to the duodenum. Endocrine portion secretes hormones into the blood stream to help the body regulate sugar
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.
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
Epinephrine . Melatonin . Glucagon 25. Which hormone secreted by the pituitary gland functions to make the tubules more permeable to water, thereby increasing water’s absorption? A. Atrial Natriuretic Hormone B. Anti Diuretic Hormene C. Follicle Stimulating Hormone D. Insulin Like Growth Factor 26.
The bulk of the pancreas is a ___________ gland. 217. What type of specialized cells are present in the pancreas to secrete pancreatic juice? 218. Where does the pancreatic duct lead to?
SCI/241 THE SCIENCE OF NUTRITION January13,2012 Human Digestion How the does the digestive system works to absorbs nutrients? Digestion starts with the smell of food, it activates the salivary glands. The gland secret saliva that moistens food, it also contains a digestive enzyme called amylase that breaks down some carbohydrates before it leaves the mouth. Then the food is swallowed and goes into the lumen through the esophagus. The esophagus muscles contractions called peristalsis forces the food through the sphincter valve and into the stomach.
The sum of all chemical reactions in the body is? Metabolism 27. Polysaccharide that serves as a storage form of energy in muscle and liver cells? Glycogen 28. Two organ systems that regulate and maintain homeostasis are the Nervous and endocrine systems 29.
Fat is also store in the system as triglycerides that forms three of our good saturated fatty acids. This process is formed on the cellular level of respiration. Adenosine triphosphate is our main source of receiving energy to the body. 1. Describe how the storage of molecules is broken down and used to produce ATP.
