|---|---|---|---|---|---|
| pharynx | where food and air passages cross
🗑
|
||||
| Salivary Amylase | enzyme in saliva which hyrdrolyzes starch to maltose (disaccharide)
🗑
|
||||
| Goblet Cells | specialized epithelial cells that secrete mucus
🗑
|
||||
| Stomach | churning produces acidic semi-fluid mixture called chyme; secretes pepsin and HCl (activates certain proteins and kills bacteria)
🗑
|
||||
| Pepsin | protein hydrolyzing enzyme; secreted by chief cells
🗑
|
||||
| parietal cells | secrete HCL, intrinsic factor (B-12 absorption)
🗑
|
||||
| Cholecytoskinin (CCK) | hormone made by cells of duodenum, stimulates bile release
🗑
|
||||
| Enterogastrone | produced in the duodenum; inhibits stomach gland secretion and slows stomach’s muscular movement when fatty food is in the intestine (more time for digestion)
🗑
|
||||
| G-cells | secrete the hormone gastrin which stimulate the HCL production of parietal cells; innervated by vagus nerve, found w/i gastric glands of stomach
🗑
|
||||
| Mucus | protects stomach from acidic environment (pH = 2)
🗑
|
||||
| Small Intestine | chemical digestion completed here; duodenum, jejunum, ileum; villi are used for absorption (contain capillaries and lacteals) / active absorption (glucose, AA) and passive
🗑
|
||||
| Most digestion done in duodenum secretes secretin | causes pancreas to secrete buffer (HCO3- )- secretions of intestinal glands, pancreas, liver and gall bladder mix
🗑
|
||||
| Intestinal mucosa secretes | lipases (fat digestion), aminopeptidases (polypeptide digestion), and disacchiridases (breakdown of maltose, lactose, sucrose)
🗑
|
||||
| Portal vein | directs glucose and other monosaccharides to the liver from the intestinal tract
🗑
|
||||
| Liver | albumin synthesis, bile production, destruction of worn-out old red blood cells, converts nitrogenous waste into urea, glycogen storage
🗑
|
||||
| Bile | emulsifies fat; contains no enzymes; exposes greater surface area of fat to lipases
🗑
|
||||
| Pancreas | produces amylase (carb digestion), trypsin (protein digestion), and lipase (fat digestion); secretes BICARBONATE juice that neutralizes chime
🗑
|
||||
| Large Intestine (colon) | functions in absorption of salts/ water not absorbed by small intestine
‑Bacteria in large intestine = main source of vitamin K
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
