Digestion & Hormone Connection Flashcards
(181 cards)
T or F: Gut dysfunction initiated early in life can carry with a person as they age, even if their nutrition and lifestyle have improved.
True
Even though most digestive symptoms may be experienced down south (via constipation, bloating, diarrhea, etc.), the dysfunction typically begins somewhere BLANK?
Up north in the GI tract.
Where does digestive function begin?
In the brain
The body can only digest food when the nervous system is in a BLANK state
Parasympathetic or relaxed state so your body is able to produce enough gastric juice and enzymes to facilitate digestion.
Chewing is important to the digestive process because BLANK?
Your taste buds tell your digestive system what’s in your food so that it can prepare the right enzymes for digestion.
What are the Salivary Amylase?
They are some enzymes actively present in your saliva which begins the breakdown for carbohydrates
What are the Salivary Lipase?
They help initiate the breakdown of fatty acids
Once the food has been chewed up and swallowed, what is its official name?
Bolus?
Once the bolus hits the esophagus, it triggers certain nerves within the esophageal muscles to initaite a movement called BLANK, which does BLANK?
Peristalsis, which forces the bolus down the long tube and into the stomach.
What is the Lower Eosphageal Sphincter?
Where the eophagus meets the stomach. This sphincter only opens to release the bolus into the stomach and then closes again shortly after as to prevent stomach acid from flowing back up into the esophagus.
Before any food reaches the stomach, it is typically at a resting pH or about BLANK, which is rather acidic.
1.5 - 3
What is acid necessary for?
Breaking down food into small enough particles to pass through the rest of the GI system.
When the bolus enters the stomach, the pH rises to about BLANK which stimulates the stomach to do WHAT?
Neutral; produce gastric juices from the parietal cells such as Hydrochloric Acid (or stomach acid) and certain enzymes that help to break down protein, B12, and minerals that are in your food.
What helps break down the food into a very acid paste called BLANK back to the pH of 1.5 - 3?
A chemical reaction alongside a mechanical reaction which is where your stomach is pulsating and churning its contents.
Chyme
Why is extreme acidity in the stomach so important?
It triggers the opening of the Pyloric Sphincter, which is the connection points between the stomach and the small intestine.
What is the small intestine known as?
The duodenum.
When the Pyloric Sphincter opens, the chyme is allowed to safely enter into the first part of the small intestine.
From there, the acidity triggers the pancreas to produce bicarbonate - a very alkaline mixture - to raise the pH of the food back to neutral.
The pancreas delivers the BLANK to help absorb the nutrients further in the small intestine.
Digestive enzymes
If fat is present in ths cyme, this triggers the duodenal cells to produce the hormone BLANK, which triggers the BLANK to squeeze stored bile into the duodenum to help emulsify the fat - or break it down into smaller particiles - which also helps with absorption.
Cholecystokinin (CCK); gallbladder
What is the primary role of the duodenum or small intestine?
As the preparation chamber, where is prepares the food content for the rest of the digestive process
Once the preparation phase is complete, the contents then enter into the BLANK where the nutrients can be absorbed into the body.
small intestine
Why is the small intestine so long?
It’s about 20 feet in length becuase the body absorbs the nutrients in our food through the same movement process, peristalsis.
As the food passes through the BLANK, finger-like projections on the intestinal epithelial cells known as villi grab onto food particles, allowing them to safely pass through the gut and into the bloodstream to be delivered to the rest of the body’s needs.
Small intestine
What is the Migrating Motor Complex (MMC?)
An electromechanical pulsation of the small intestine that causes your stomach to “growl” when you’re hungry.
Happens in times of fasting when there is no food within the small intestine as an effort for the body to “clear and clean” the intestines of debris.
It is one of the primary benefits of intermittent fasting.
