Digestion Part 2 Flashcards
What is the swine stomach like?
Muscular & Thick Lining
Hydrochloric Acid (Stress)
What is the horse stomach like?
Larger than other species
Two Regions (Glandular & Non Glandular/Sqamous) which are divided by the margo placatus
Ulcers (Stress)
Larger abomasum?
Transformation?
Food out of rumen into a sick animal
Gastrin
Hormone that causes release of digestive enzymes
Released in response to stimuli (stomach dissension, presence of partially digested proteins especially amino acids, hypercalcemia)
Inhibited by presence of acid in stomach HCI
Somatostatin
Hydrochloric Acid
Activates Pepsin
Constitutes the majority of gastric acid
Secreted by parietal cells (block)
Dissolve everything in the stomach
Activate Pepinogen
Pepsinogen
Pepsin is a proteolytic enzyme that begins protein digestion
Released by the chief cells
Degrades food proteins into peptides
Rennin
Natural complex of enzymes produced in any mammalian stomach to digest the mother’s milk
Kidney Brown Adipose Tissue(Make heat/warm)
Mitochondria
Small Intestine
Duodenum
Jejunum
Ileum
Duodenum
Receives Secretions from Pancreas and Brunner’s Gland
* secrets majority of digestive juices with hormonal secretion
Ase
Enzymes
Jejunum
- active site of nutrient absorption
(Amino acids, sugar molecules, fatty acids, glycerol)
Vili- increase absorption area (pulpili in rumen)
Ileum
Active site of nutrient absorption
(As much absorbed as it can)
Liver (everything happens)
Bile salts (emulsify fats, activate lipase)
Cholesterol
* bile salts emulsify fats and neutralize acidic chyme are stored in the gall bladder (goes to be clean )
Vitamin A liver ?
Large Intestine
- Three sections
Cecum, Colon, Rectum
*Microbial digestion~ VFA, MCP - Absorption of water
- Synthesis of B Vitamins
Large Intestine (Horse)
- 60 % of GIT (cecum, large colon, small colon, rectum)
*Cecum (Bacterial Function / breakdown )
synthesis of water soluble vitamins and vitamin K
proteins considered of limited value to horse
