Ruminant - Mouth/Teeth (F)

(Ruminant)

starting point of digestion
\-chemical = saliva
\-mehanial = teeth

Ruminant - Salivary Glands (E)

(Ruminant)

Secretes saliva to aid in digestion

Ruminant - Reticulum (G)

\-honeycomb
\-filter foodstuffs
\-holds foodstuffs
\-site of regurgitation

\-1st compartment

Ruminant - Rumen (C)

\-fermentation vat
\-not active in early stages of life
\-microbial digestion
\-gas -carpet -80%

\-2nd compartment

Ruminant - Omasum (H)

\-many folds (book)

\-dries foodstuffs

\-absorbs water & nutrients

\-abnormal for a stomach to absorb nutrients

\-3rd compartment

Ruminant - Abomasum (I)

\-“true stomach”
\-acidic digestion
\-hydrochloric acid
\-same as mono gastric
\-pepsin breaks down proteins
\-renin breaks down milk

\-4th compartment

Ruminant - Large Intestine (B)

-absorbs water to send to blood stream
-formation of feces

Ruminant - Small Intestine (J)

(Ruminant)

\-absorption of nutrients
\-main site
\-absorbs to the bloodstream
\-3 sections (Dw about them)

Ruminant - Cecum (K)

-helps break down fiber
-full function still unknown

Ruminant - Anus (A)

(Ruminant)

\-excretes fecal matter

Monogastric - Mouth/Teeth/Tounge (A)

(Monogastric)

\-begins mechanical (teeth) & chemical (saliva) digestion

Monogastric - Salivary Glands (B)

(Monogastric)

\-produces saliva, which aids in chem digestion

Monogastric - Esophagus (C)

“food tube” - transports food to stomach (moistened by saliva)

Monogastric - Stomach (D)

- churns & mixes food - uses acidic digestion to break food down further (bottom is lined to protect from digesting itself)

Monogastric - Large Intestine (I)

-absorbs water / dries

Monogastric - Small Intestine (E)

(Monogastric)

\-does enzymatic digestion and absorbs nutrients

Monogastric - Pancreas (J)

produces & secretes enzymes

Monogastric - Gallbladder (K)

stores bile

Monogastric - Cecum (F)

no function in most monogastrics; in modified monogastrics (hind-gut fermenters) it ferments roughages (similar to a rumen in ruminants)

Monogastric - Colon (G)

end of large intestine - storage of fecal matter

Monogastric - Anus (H)

(Monogastric)

excretes fecal matter

Female - Uterus (A)

-where the egg attaches
-the “womb”

Female - Cervix (B)

\-tight barrier between itself and uterus

\-site of artificial insemination (AI)

Female - Vagina (C)

-“tube”
-site of natural insemination (NI)
-most common site of infection

Female - Vulva (D)

-“entryway”
-swells & covers w/ mucus during estrus

Female - Oviducts (F)

\-where egg is released during corpus luteum

\-path between ovaries and uterine horns

Female - Ovaries (G)

-holds egg supply (finite)
-releases egg during ovulation

Female - Uterine Horns (E)

-between ovary & uterus
-length/development determines reproductive capability (size of litter)

Male - Scrotum (B)

outside skin, protects testes slightly from outside world. rises and lowers based on temperature

Male - Testicle (C)

produces spermatozoa

Male - Head of Epididymus (D)

stores immature sperm cells

Male - Tail of Epididymus (A)

stores mature sperm cells

Male - Prostate Gland (Unlabeled)

-adds a buffer solution (change in pH) for sperm cells to survive in female repro. this is what becomes semen

Male - Cowper’s Gland (E)

-cleans remaining urine out of urethra
-“m y q u e e n” (v. sorry to the rest of you this is only for bella and brady)

Male - Sigmoid Flexure (Unlabeled)

-fills with blood, enlarges in order to be inserted into a vagina

Male - Retractor Muscle (G)

pulls sigmoid flexure back when reproduction is finished

Male - Vas Deferens (F)

transports sperm from epididymis to prostate

Monogastric - Liver (L)

produces bile
