Non-ruminants (Digestive Parts) Flashcards
This is where digestion process begins. It contains teeth for mastication (chewing) to break down food into smaller particles. The salivary glands
Mouth
A muscular tube that connects the mouth to the stomach. It transports the masticated food to the stomach through peristaltic movements.
Esophagus
A muscular organ where food is mixed with gastric juices containing hydrochloric acid and digestive enzymes like pepsin. This results in the breakdown of proteins and the conversion of food into a semi-fluid mixture called chyme.
Stomach
This is the primary site for digestion and absorption. It has 3 parts.
Small Intestine
Part of the SMALL INTESTINE that receives chyme from the stomach and digestive enzymes from the pancreas and bile from the liver.
Duodenum
Part of the SMALL INTESTINE that is where a significant portion of nutrient absorption takes place.
Jejenum
Part of the SMALL INTESTINE that is the final segment that absorbs the remaining nutrients.
Ileum
Produces digestive enzymes that are released into the duodenum.
Pancreas
Produces bile which is stored in the gallbladder and released into the duodenum as required. Bile helps in the emulsification of fats, preparing them for digestion by lipase.
Liver
A small organ that stores bile produced by liver and releases it into duodenum when needed.
Gallbladder
It is where any undigested and unabsorbed food moves. Here, water and electrolytes are reabsorbed, and the remaining waste material is compacted into feces. Beneficial bacteria present in the colon also help break down some of these residues, producing certain vitamins in the process.
Large Intestine (Colon)
Stores feces until it is expelled from the body.
Rectum
The terminal end of the digestive tract where feces are expelled from the body.
Anus
