- tongue
-
Has series of small projections called papillae
F: ingestion - epiglottis
-
Small triangular projection (flap of tissue) at back of the throat
Function: covers the opening to the windpipe (trachea) when you swallow food→ prevents choking - larynx
-
The enlarged portion of the trachea
Function: Voice box, protects trachea (adam's apple) - parotid gland
-
Large, granular, diffuse looking gland
Located above the submaxillary gland
Sometimes sticks to skin
See fig. 4 in manual (book/online)
Function: salivary gland (like submaxillary gland) - submaxillary gland
-
⬢ Small bean shaped gland posterior to the masseter muscle (the large round muscle on the curve of the jaw)
under parotid, above thymus (Fig 3)
now called "submandibular gland"
produces saliva - thymus glands
-
⬢ Long pinkish glands on either side of the trachea
⬢ Function: important part of immune system
o As pig matures, these glands degenrate - thyroid gland
-
⬢ Small dark brown or pink gland sitting on the trachea, just above rib cage
⬢ Function: regulates metabolism by producing various hormones. - liver
-
⬢ Large red-brown
⬢ Just below diaphragm
⬢ Function:
-Produces Bile
-metabolism regulation
-waste removal - diaphragm
-
sheet of muscles
anterior to liver
seperates thoracic & abdominal cavities
Function: Important for respiration - gall bladder
-
• Small sac-like organ under the liver
• On pig’s right side
• May be slightly green, or same color as liver
• Function: stores bile, releases bile - stomach
-
⬢ Sac-like organ posterior to the liver
⬢ Function: Digestion of food (but not absorption of nutrients) - spleen
-
⬢ Reddish strap-like organ along outer curve of stomach
⬢ Function: plays role in immunological processes - Pancreas
-
⬢ under stomach
⬢ Triangular shaped, pink or gray granular looking organ
⬢ 2 functions:
-Produces insulin for regulation of blood sugar levels
-Secretes pancreatic juice into S.I. which contains digestive enzymes - small intestine
-
connects to stomach
⬢ Nutrients from food are absorbed here - large intestine
-
water reabsorbed
undigested food consolidated
moves waste to anus - caecum
-
⬢ Function: A blind sac that functions as a fermentation reservoir with bacteria that help digest cellulose.
⬢ At the junction of small and large intestines - colon
-
⬢ After large intestine
⬢ Leads to rectum and anus
