I think it's E too.

  #5

Secretion by regulation

  #6

I think it is C because enteroendocrine (EEC) cells are endocrine cells so their granules are located in the basal part of the cell from where they secrete their products into blood.

Goblet cells (GC) have secretory granules in the apical part of the cell from where they secrete their products into the lumen of intestines. Both EEC and GC have regulated secretion i.e. they secrete their products on stimuli


  #7

I am not sure the answer. But I found this to support Mildus.

Another cell type in the stomach is the enteroendocrine cell. This cell is polarized in the opposite direction to that of the other gland cells. It lies at the base of the glands, underneath the chief or parietal cells. Its secretory granules face the blood vessels in the lamina propria.


  #8

What types of hormones do the enteroendocrine cells in the stomach secrete?


  #9

Secretion of mucus from goblet cells is elicited primarily by irritating stimuli rather than in response to hormones.

  #10

[IN STOMACH] G Cells___ Gastrin ; EC Cells___ Secretin and Histamin ; A Cells___ Glucagon ; D Cells____ Somatostatin

[IN SMALL INTESTINE] I Cells ___ CCK ; S Cells___ Secretin ; K Cells___ GIP ; L Cells___ GLP {GIP and GLP increase Insulin release ,others are obious}
