GI tract)
Slide4Slide5Salivary Gland
Slide6Slide7Slide8Slide9Gastric Gland
Slide10Slide11Slide12Villi are small finger-like projections located in the walls of the small intestine. Their function is to increase the surface area in order to maximise the absorption of digested food.
Slide13Structure
of villus
Slide14Glands associated with SI Liver: Produce bile and store in GallbladderPancreas: Produce Pancreatic Juice
Slide15Slide16Large Intestine
Slide17The taeniae coli (also teniae coli or tenia coli) are three separate longitudinal ribbons (taeniae meaning ribbon in latin
) of smooth muscle on the outside of the ascending, transverse, descending and sigmoid colons.The teniae coli contracts length wise to produce the haustra, the bulges in the colon. Haustra are pouches in the colon that give it its segmented appearance. Haustral contraction is activated by the presence of chyme and serves to move food slowly to the next
haustra
, along with mixing the
chyme
to help with water absorption
.The mesoappendix is the portion of the mesentery connecting the ileum to the appendix. It may extend to the tip of the appendix. It encloses the appendicular artery and vein, as well as lymphatic vessels, nerves, and often a lymph node.
