Place a single word into each sentence to make it correct, then arrange each sentence into a logical paragraph order. Not all terms will be used.
In the gastric gland, the CHIEF cells secrete pepsinogen.
Also in the gastric gland, the parietal cells will secrete HCI.
HCL will remove some amino acids from pepsinogen and turn it into PEPSIN.
Pepsin enzymes can then digest dietary PROTEINS in the lumen of the stomach.
Place a single word into each sentence to make it correct, then arrange each sentence into a logical paragraph order.
The act of protein digestion begins in the mouth with MECHANICAL digestion.
Once in the stomach, PEPSIN hydrolyzes peptide bonds.
Then, in the small intestine, trypsin, chymotrypsin, and CARBOXYPEPTIDASE will continue the breakdown and begin absorption.
The BRUSH border in the intestines will finish the breakdown and begin absorption.
Drag each label into the appropriate position in order to identify whether the structure is associated with the large or small intestine.
Drag each label into the appropriate position in order to identify which type of macromolecule is the target of each digestive enzyme or compound.
Complete each sentence by dragging the proper label into the appropriate position.
Three main vessels make up the HEPATIC TRIAD including the HEPATIC PORTAL vein, HEPATIC artery, and BILE ductules.
The hepatic portal vein delivers nutrient rich, oxygen POOR blood to the liver cells.
The HEPATIC ARTERY is responsible for delivering oxygen RICH blood to the hepatocytes and thus providing for the large metabolic demand for this tissue.
The HEPATIC DUCTULES collect bile produced in the hepatic lobules and deliver it to the hepatic ducts on their way to the GALLBLADDER for storage.
