The 2 groups of organs that compose the digestive system

Gastrointestinal tract, Accessory digestive organs

Churns food

Mechanical digestion

Hydrolysis

Chemical digestion

Passing into blood or lymph

Absorption

Elimination of feces

Defacation

Connective tissue with blood and lypmhatic vessels and mucosa-asscociated lymphatic tissue

Lamina propria

Thin layer of smooth muscles making folds to increase surface area

Muscularis mucosae

Connective tissue binding mucosa to muscularis

Submucosa

Contains many blood and lymphatic vessels

Submucosa

Voluntary skeletal muscle found in mouth, pharynx, upper 2/3 of esophagus, and anal sphincter

Muscularis

Outermost covering of organs suspended in abdominopeliv cavity

Serosa

It is also called Visceral peritoneum

Serosa

It is the intrinsic set of nerves and also the "brain of gut"

Enteric nervous system

Extrinsic set of nerves

Autonomic nervous system

It controls secretions

Submucosal plexus

Gastrointestinal tract motility

Myenteric plexus

It increases secretion and activity by stimulating ENS (Enteric Nervous System)

Parasympathetic stimulation

Decreases secretion and activitiy by inhibiting ENS (Enteric Nervous System)

Sympathetic stimulation

Lines wall of cavity

Parietal peritoneum

Covers some organs and is also called serosa

Visceral peritoneum

Oral or buccal cavity. Formed by cheeks, hard and soft palates, and tongue

Mouth

It is the act of swallowing and is facilitated by secretions of saliva and mucus

Deglutition

Bolus passes to oropharynx

Voluntary

Involuntary passage though pharynx into esophagus

Phrayngeal

Involuntary passage through esophagus to stomach

Esophageal

Serves as mixing chamber and holding reservoir

Stomach

Mixing waves - gentle, rippling peristaltic movements - creates chyme

Mechanical digestion

Digestion by salivary amylase continues until inactivated by acidic gastric juice

Chemical ingestion

Acidic gastric juice activates lingual lipase

Chemical digestion

Parietal cells secrete H+ and Cl- separately but net effect is HCl

Chemical digestion

Mixture of fluid and digestive enzymes

Pancreatic juice

Pancreatic juice has ____-____ml daily

1200-1500

Heaviest gland of the body

Liver

Major functional cells of the liver

Hepatocytes

Ducts between hepatocytes that collect bile

Bile canaliculi

Highly permeable blood capillaries receiving oxygenated blood from hepatic artery and deoxygenated nutrient-rich blood from hepatic portal vein

Hepatic sinusoids

Contraction of smooth muscle fibers eject content of gallbladder into cystic duct

Gallbladder

Functions to store and concentrate bile produced by the liver until it is needed in the small intestine

Gallbladder

Absorbs water and ions to concentrate bile up to tenfold

Gallbladder

Principal bile pigment

Bilirubin

It's overall function is to complete absorption, produce certain vitamins, and form and expels feces

Large intestines

Smell, sight, thought or initial taste of food activates neural centers - prepares mouth and stomach for food to be eaten

Cephalic phase

Neural and hormonal mechanism promote gastric secretion and motility

Gastric phase

Begins when food enter small intestine, slows exit of chyme from stomach, and stimulates flow of bile and pancreatic juice

Intestinal phase
