Digestive System Flashcards
What are the 6 major functions of the digestive system

Excretion, absorption, secretion, digestion, ingestion, mixing and movement
An action used to push down food is referred to as?
It is a muscular wave that travels the length of the GI tract, moving partially digested food a short distance down the tract.
Peristalsis
The teeth, tongue, and salivary glands in the digestive system are called
Accessory
Small and large intestines, stomach, liver, pancreas, gallbladder, and esophagus in the digestive system are called
True organs
The stomach, which is a true organ, consists of four regions that include:
Cardia, fundus, body, pylorus
Also known as the alimentary canal, consists of the pharynx, esophagus, stomach, small and large intestines, and the oral cavity, all of which work together to digest food.
Gastrointestinal tract (GI) tract
The small intestines consist of three major parts:
Duodenum, Jejunum, Ileum
The cecum, ascending, transverse, descending, and sigmoid colon, and rectum are part of the
Large intestines
- Known as the beginning of the digestive tract
- Oral cavity where teeth grind the food
- Saliva mixes with food, which turns it to a form that the body absorbs and utilizes as nutrients
Mouth
1.Also known as the throat
2.Connects nasal and oral cavities with the larynx and esophagus
3.Transport food to esophagus
Pharynx
Thin, long, muscular tube connecting the throat to the stomach
Transports food to stomach by utilizing the process of peristalsis ( series of wave-like muscle contractions)
Esophagus
Largest internal organ of the human body; located on the right side of the stomach
It has many functions, but the main one is to filter blood coming from the digestive tract before it goes to the rest of the body
Produces bile
Liver
Located behind the stomach and rests on the small intestine
Responsible for producing digestive liquids that help the intestines break down food, insulin, and other hormones
Store biles
Gallbladder
1.Muscular structure located on the left side of the upper abdomen
2. Food mixes with gastric juices through peristalsis, which assists in breaking down the food
3.Moves chyme (ground-up food) to the duodenum
4.Temporary storage container for food and other products
Stomach
Located right under the liver and to the right of the abdomen
Holds the bile and later helps to digest the fats from foods
Pancreas
- Longest organ of the gastrointestinal tract
- Absorb nutrients and transport waste to large intestines
- The duodenum’s primary responsibility is to facilitate the breakdown of foods
- The jejunum and ileum are largely responsible for the absorption of nutrients into the bloodstream
Small intestines
Connect small intestines to rectum
Absorb water and electrolytes
Responsible for dehydrating digestive residues ( fecal matter)
Stool is stored into sigmoid until emptied into the rectum
Large intestines
- Connects colon to anus
- Approximately eight inches
3.Sensors signal the brain letting a person known when it’s time to empty
4.sphincter will either relax or contract.
Rectum
- About two inches long and is considered to be the last part of the digestive system.
- Contains a sphincter that detects liquid, gas, or solid contents.
- Contents are expelled through it.
