Peritoneum
the serous membrane lining the cavity of the abdomen and covering the abdominal organs. Parietal peritoneum- lines inner surfaces of body wall, Visceral peritoneum- covers organs, Peritoneal fluid- provides lubrication, separates peritoneal surfaces and allows sliding without friction.
-
Mesentery
double sheet of peritoneal membrane separated by loose C.T. a fold of the peritoneum that attaches the stomach, small intestine, pancreas, spleen, and other organs to the posterior wall of the abdomen.
-
lesser omentum
the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum.
-
greater omentum
A peritoneal fold passing from the stomach to the transverse colon, hanging like an apron in front of the intestines
-
peristalsis
waves of muscular contractions, moves bolus further down
-
segmentation
random ringlike constrictions that mix and churn contents with intestinal secretions
-
epiploic appendages
Fatty tissue on the out wall of the large intestine.
-
enamel
strongest structure of the entire body, hard part of tooth.
-
periodontal ligament
ligament anchors the teeth to maxilla and mandible.
-
taenia coli

-
bile acids
(salts) emulsify fats and aid in their digestion kupffer cell
-
parietal cell
an oxyntic (acid-secreting) cell of the stomach wall, secrete HCL and intrinsic factor.
-
chief cell
secrete pepsinogen, Pepsinogen convers to pepsin which digests proteins.
-
absorptive cell
the predominant epithelial cell type lining the lumen of the small intestine and colon. These cells are specialized for absorption of nutrients across the apical plasma membrane and export of these same nutrients across the basal plasma membrane.
