Most Digestive organs are covered by Serous Membrane known as (outer covering) ____________
The Space between the Visceral and Parietal Peritoneum
What purpose does the Peritoneal fluid serve in the Peritoneal Cavity?
Lubricates the visceral and peritoneal membranes... decrease friction

What Organs have no Mesentery? (within the digestive system)
*What is the special name for these guys*
Pancreas & Large Intestine
These structures are called retro-peritoneal
Walls of the Digestive Tract consist of 4 layers... What are they going from the "Inside --> Out" ?
Mucosa --> Submocosa --> Muscularis Externa --> The Serosa
What is the Mucosa composed of? (2 major terms/layers)
Epithelial Layer: Stratified... Oral cavity, Esophagus... Simple (stomach, small intestine)
Lamina propria: blood vessels, mucous glands, sensory nerve endings ...
One of the 4 tissue layers of the Alimentary Canal **Mocosa, Submucosa, Muscularis externa and Serosa** is responsible for Peristalsis... which one is it?
Muscularis externa... This region is dominated by smooth muscle cells
This layer of alimentary canal contains, blood vessels and some exocrine glands that secrete buffers/enzymes into lumen of digestive tract... which one?
