function of the digestive system
|
Securing food
Conducting and storing food Mechanical and chemical digestion Absorption of food |
|
mouth
|
Buccal or oral cavity
Obtains food Provides for mechanical breakdown of food Assisted by: teeth, tongue and salivary glands (provide enzymes for breakdown of food |
|
pharynx
|
Crossover for digestive and respiratory system
Muscular tube Connects the back of the nasal and oral cavity with the esophagus and larynx/trachea Conveys food from mouth to esophagus by process of deglutition (swallowing) |
|
|
|
|
|
|
|
intrinsic glands
|
In walls, release secretions into lumen (mucus, enzymes)
|
|
extrinsic glands
|
Outside the walls, deliver secretion to lumen via ducts (salivary glands, pancreas, liver)
|
|
esophagus
|
Muscular tube that conducts food from the pharynx to the stomach by peristalsis
|
|
stomach
|
Muscular-glandular sac for storage and chemical digestion
|
|
small intestines
|
Long thin tube with expanded luminal surface area
Designed for further digestion Main function is for absorptions of digested carbohydrates, protein and fat |
|
large intestine
|
Wider and shorter than small intestines
Mainly designed for absorption of water Rectum is designed to store waste until it is expelled from anus |
|
|
|
|
peritoneum is
|
Smooth shiny serous membrane
Lines the abdominal cavity and party of the pelvic cavity |
|
peritoneum is composed of
|
Surface layer of simple squamous epithelium (mesothilium) which lies on a layer of connective tissue containing blood vessel nerves and lymphatics.
Semi permeable to water and small molecules. |
|
the function of peritoneum is
|
secret the watery peritoneal fluid that acts as a lubricant to decrease friction
|
|
peritoneal cavity
|
Cavity enclosed by peritoneum
Divided into peritoneal portion and pelvic portion |
|
parietal peritoneum
|
Peritoneum attached onto wall of abdominal wall of the abdominal cavity
|
|
visceral peritoneum
|
Peritoneum lining the external surfaces of the viscera (soft internal organs)
|
|
connecting peritoneum
|
Composed f double serous membranes
|
|
mesentary
|
Peritoneum from the intestine to the dorsal wall of the abdominal cavity
|
|
common or great mesentary
|
Connects most of the small intestine to the abdominal roof at the level of the first or second lumbar vertebrae.
|
|
mesocolon
|
Attaches the colon (large intestine) to the abdominal roof and continues into the pelvic inlet as the mesorectum
|
|
greater omentum
|
Peritoneum from the stomach to the wall of the abdominal cavity or other viscera
|
|
lesser omentum
|
Passes from the lesser curvature of the stomach to the liver
|
|
ligament
|
Reflections of the peritoneum between the viscera, or between viscera and the abdominal wall.
