Organs
This muscular organ churns food to further break it down into chyme, the semi-liquid mixture that moves into the small intestine.
Stomach
This voluntary process is the first step of digestion, where food enters the mouth.
Ingestion
What is the process by which the body breaks down food into smaller molecules to absorb nutrients?
Our bodies get the energy they need from food from the process of
Metabolism
This condition is characterized by the inability to digest lactose, causing bloating and diarrhea.
Lactose Intolerance
The absorption of nutrients happens primarily in this organ during the digestive process
Small Intestine
This process eliminates indigestible substances from the gastrointestinal tract in the form of feces and is the final step in digestion.
Defecation
These structures in the small intestine increase surface area for absorption.
Villi
_______is the process that produces the energy required for all activity in the cells.
Catabolism
This happens when intestinal contents have moved too quickly through the intestines for fluid absorption to take place
Diarrhea
In this component of the digestive system, secretion of lubricating fluid containing enzymes that start breaking down carbohydrates
Salivary Glands
This muscular movement is involuntary and involves alternating waves of contraction and relaxation to push food through the digestive tract
Peristalsis
This is the acid found in the stomach that aids in the breakdown of food
Hydrochloric Acid
It supports the growth of new cells, the maintenance of body tissues, and the storage of energy for use in the future.
Anabolism
This disorder occurs when the gallbladder forms stones that block bile flow.
Gallstones
This tube connects the mouth to the stomach and uses peristalsis to move food from one end to the other, bypassing the mechanical digestion process.
Esophagus
These four organs secrete digestive enzymes or juices that assist in the breakdown of food during digestion.
Salivary glands, stomach, pancreas, and small intestine
This enzyme in the stomach breaks down proteins.
Pepsin
This process converts excess glucose into glycogen for storage, primarily in the liver and muscles.
Glycogensis
This condition occurs when stomach acid flows back into the esophagus, causing discomfort
Gastroesophageal reflux disease (GERD)
This valve controls the passage of digested food from the small intestine to the large intestine and prevents backflow.
Ileocecal Valve
These five structures are involved in the mechanical and chemical breakdown of food
Teeth, Tongue, salivary glands, stomach, and pancreas
When chyme enters the small intestine, it triggers the mucosal cells to release hormones like this one, which stimulates the pancreas to release bicarbonate-rich juice
Secretin
During this process, the liver breaks down stored glycogen to release glucose into the bloodstream.
Glycogenolysis
This autoimmune disorder affects the small intestine, preventing nutrient absorption.
Celiac Disease
