What are the functions of the digestive system?
|
Parietal Cells
What cell secretes HCL?
|
Need to be consumed in large quantities
What are macronutrients?
|
building up (small to large)
What is anabolic reactions?

|
List the digestive layer tract from superficial to deep
Serosa Muscularis Externa Submucosa Mucosa
List the digestive layer tract from superficial to deep
|
histamine
What does ECL cells secrete?
|
Components of RNA & DNA Sell signaling Energy Components of some vitamins found between joints to provide cushioning & lubrication
What are the functions of Carbohydrates?
|
breaking down (large to small)
What is catabolic reactions
|
pyruvate
What is made during glycolysis?
|
|
Peristalsis: coordinated muscle contractions & relaxation. Wavelike movements. Bolus moves forward. Seen a lot in the esophagus
Segmentation: simultaneous muscle contractions. back and forth movements. bolus gets mixed with digestive enzymes. promotes mixing Peristalsis: coordinated muscle contractions & relaxation. Wavelike movements. Bolus moves forward. Seen a lot in the esophagus
What is the difference between peristalsis and segmentation?
|
HCO3 pumps into the bloodstream making it more alkaline (basic)
What is the "alkaline tide"?
|
Saturated Fatty Acids
What type of fat is solid at room temperature?
ex. Butter |
high blood glucose
In the absorptive state pancreas produces insulin in response to what?
|
32
How many ATP are made during oxidative phosphorylation?
|
|
Oral cavity: both
stomach: both duodenum: chemical jejunum: chemical
Where does mechanical or chemical digestion in the oral cavity, stomach, duodenum, and jejunum?
|
binds to gastrin to shut everything down
When is somatostatin released? |
produced by the body
What are non-essential proteins?
|
glucagon
In the post-absorptive state what does the pancreas release in response to low blood glucose?
|
36
How many ATP are made per 1 molecule of glucose? |
|
Epiglottis cartilage covers the opening of the larynx
upper esophageal sphincter relaxes food moves safely into esophagus
What happens during the epiglottis bend phase during swallowing?
|
To pump H+ ions into the lumen of the stomach because it is going from low to high concentration
Why is an active pump needed?
|
ADEK
What are the lipid soluble vitamins?
|
excess glucose converted to glycogen What happens in the liver during the absorptive state? |
mitochondria
Where does the citric acid occur? |
