Chapter 50.3, Problem 5R
Summary Introduction
To review:
In ruminants, HCl is secreted only in the abomasum.
Introduction:
Ruminants are animals like cows, goats, and giraffe, which are capable of obtaining nutrition directly from plants as they have the ability to break down cellulose. They have a mechanism to ferment their food before digesting it.

All the structures of the alimentary canal have 4 similar major histological tissues . Which of the following descriptions of the tissue layers contains innacurate information?
A) The mucosa layer consits of a simple epithelium (responsible for absoprtion), a lamina proprioa (supports the epithelium) and muscularis mucosae (thats ivolved with peristalsis.
B) The muscularis externa has 2 or 3 layers of smooth msulce and is involced with persistalsis
C) The submucosa layer is a connective tissue layer that anchors the mucosa layer and contains many blood vessels, lyphatic vessels, and nerves
D) The serosa layer is a connective tissue layer that tethers the alimnetary canal to the appropirate body cavitities.
I believe that D is false but I am not certain
A histological specimen of submandibular salivary gland represents basket *
cells from which some processes radiate and embrace the secretory unit.
Contraction of the processes of these cells helps in expelling secretions
from the lumen of secretory units and moving them to the system of
excretory ducts. Name these cells:
Serous cells
O Mucocytes
Epithelial cells
O Adipocytes
O Myoepithelial Cells
In the duodenum lipid stimulate cck secretion. Explain how this would affect gastric emptying, pancreatic function, gallbladder secretion, and the sensation of hunger.
