Anatomy and Physiology Gastro System Flashcards
What two cells initiate chemical digestion of starch and lipids and produced by saliva?
amylase and lipase
What is the chemical digestion of proteins initiated by in the stomach?
pepsin
What are the chief, goblet, and parietal cells of the stomach?
pepsinogen(chief cells) mucus (goblet cells) hydrochloric acid (parietal cells)
Where is chyme located in the small intestine ?
duodenum
What is a series of muscle contractions that move food through the digestive tract?
peristalsis
Why would liver failure is a critical health emergency?
liver filters digestion products and produce urea as waste
What is the carbohydrate- digesting enzyme produced by salivary glands?
salivary amylase
What is the zymogen form of protease produced by the stomach?
pepsinogen
Cells that produce acid in the stomach
parietal cells
Valve through which chyme passes from stomach to duodenum
pyloric sphincter
Hormone produced by stomach that induces stomach secretions
gastrin
Hormone that induces bile and pancreatic juice secretion
cholesystokinen
second section of small intestine where majority of absorption occurs
jejunum
blood vesselsl that carries nutrients directly from small intestine to liver
hepatic portal
Substance mainly absorbed from waste in large intestine
water
