The pharynx is the passageway leading from
Esophagus
Secreted by the pancreas, stimulates gastric acid production
Hydrochloric acid
Secreted by stomach and pancreas and breaks down fats
Lipase
Secreted by the pancreas and raises blood sugar
Glucagon
Secreted by the pancreas and breaks down proteins:
Trypsin
In this first segment of the small intestine, food is mixed with enzymes and bile to help break down food:
Duodenum
In this segment of the small intestine, the walls are made of circular folds to increase the surface area for absorption:
Jejunum
In this segment of the small intestine, bile acids and vitamin B12 are absorbed.
Ileum
The initial phase when food is taken into the digestive tract:
Ingestion
Accessory Organs of the Digestive System are
teeth, tongue, glandular organs, liver, gallbladder, and pancreas.
What is the main purpose of the villi in the small intestine?
Increase surface area for absorption
What does the pancreas produce to aid in digestion?
Enzymes and hormones
When food is transferred through the GI tract using swallowing and peristalsis
Propulsion
What is the main role of the gallbladder?
Produce, concentrate, and thicken bile.
What is/are the roles of the Liver?
Produces bile. It breaks down fat into smaller manageable droplets(emulsification). Filters out toxins.
What is the role of the Large Intestine?
Reabsorbs water and mineral irons. Forms feces.
When nutrients, water and electrolytes are transferred from the small intestine into cells and blood
Absorption
What enzyme breaks down proteins in the stomach?
Pepsin
secreted by the pancreas, lowers blood sugar
Insulin
secreted by pancreas, controls appetite
Amylin
secreted by gallbladder and lives; emulsifies fats
Bile
secreted by salivary glands and pancreas.
Amylase
Celiac
autoimmune disease from eating gluten
Peptic Ulser
sore I esophagus, stomach, or small intestine
