• Endoderm.

• Ectoderm.

• Prenotochordal plate.

In a patient with chronic enterocolitis (inflammation of the intestine), a violation of digestion and absorption of proteins in the small intestine was found as a result of an insufficient amount of dipeptidases in the intestinal juice. In what cells is the synthesis of these enzymes disrupted?

• Columnar with edge

• Cells Of Paneth

• Columnar without edges

• Goblet-shaped

The histological micrograph shows the body of the stomach. What tissue forms the submucosa (3.1) membrane?

• Loose fibrous connective.

• Smooth muscle.

• Dense fibrous loose connective.

• Dense fibrous formed connective.

The epithelium of the colon mucosa differs from the epithelium of the small intestine:

• a large number of goblet cells

• cell shape

• lack of limb epithelial cells

• lack of borderless epithelial cells

How many layers the muscularis externa of the stomach has?

• An innner oblique layer , a middle circular and an external longitudinal layer.

• An innner oblique layer ,an external longitudinal layer.

• one layer of smooth muscle

• An innner circular layer ,an external longitudinal layer.

In human, as a result of chronic gastritis, the structure of the mucous membrane is disturbed, all indicators of the acid-forming function of the stomach are reduced. The most significant negative consequence of this will be a violation ...

• protein digestion 

• pancreatic juice secretion

• secretin secretions

• evacuation of the chyme into the 12 duodenum

.The structure on the histological preparation of the organ parenchyma is represented by lobules, which are shaped like hexagonal prisms and consist of anastomosing beams, between which lie sinusoidal capillaries that radially converge to the central vein. What anatomical organ has this morphological structure?

• Liver 

• Pancreas

• Thymus 

• Spleen
