What digestion does saliva help with?
Chemical digestion
What is it called the solid food that becomes a semi-liquid mixture in the stomach?
Chyme
undigested food remains are removed from the body throughout what process?
Defecation
What is the process of breaking large food molecules down into simpler molecules?
Digestion
What are the sections of the small intestine?
Duodenum, jejunum and ileum
What describes the contractions of smooth muscle that keep food moving?
Esophagus
Stores bile, the contractions makes food available to duodenum and is in the liver
Gall bladder
Produce hydrochloric acid and pepsinogen
Gastric glands
Where can you found saliva?
In the mouth
Name 4 types of teeth you have in your mouth
Incisors, canines, premolars and molar
Physiology of the digestive system
Ingest, digest, absorb and eliminate
Produce an enzyme-poor "juice" containing mucus; found in the submucosa of the small intestine
Intestinal glands
Organ closest to the end of small intestine
Large intestine
Produces bile, which is transported to the duodenum via the bile duct
Liver
What process breakdown food in the mouth and turns it into smaller pieces when you chew?
Mechanical digestion
Where does digestion begin?
Mouth
Alimentary organs through which food moves while it is being processed by the digestive system
Mouth, pharynx, esophagus, stomach, small intestine, large intestine
Tissues layers from the esophagus to the large intestine
Mucosa, submucosa, muscularis externa and serosa
Parts of the pharynx that are parts of the digestive system
Oropharynx and laryngopharynx
Ducts a variety of enzymes in an alkaline fluid into the duodenum
Pancreas
What organ releases juices into duct and produces enzymes that break down food?
Pancreas
What organs help to complete digestion in the small intestine?
Pancreas, liver and gallbladder
Types of digestive cells which help to do its digestive job
Parietal, chief and pepsinogens cells
It has the function to swallow the food and is a pathway to the esophagus
Pharynx
chemical digestion
Process by which enzymes break down food into small molecules that the body can use
The movement of food along the digestive tract
Propulsion
What does salivary glands release into the mouth?
Saliva
Secretion includes amylase, which begins starch digestion in the mouth
Salivary glands
What are the accessory organs of the digestive system?
Salivary glands, teeth, pancreas, liver and gallbladder
Villi
Small fingerlike projections on the walls of the small intestines that increase surface area to absorbs nutrients
Absorbs nutrients into the bloodstream, covered by the villi, digest proteins, fats and carbs.
Small intestine
Good moves from the stomach into the...
Small intestine
Where is digestion completed?
Small intestine
Why the digestive system processes food?
So that the food can be absorbed and used by the body's cells
What separates each digestive organ from the next?
Sphincter
Organ closest to the beginning of the small intestine
Stomach
What organ can stretch to twice it's original size?
Stomach
Functions of the teeth
Tear and grind the food, breaking it down into smaller fragments
Absortion
The process by which nutrient molecules pass through the wall of the digestive system into the blood
What are the two sections of the mouth?
Vestibule (between the cheeks) and oral cavity proper ( area by the teeth)
divisions of large intestine
cecum, appendix, colon, rectum, anal canal
defecation
elimination of feces from the digestive tract through the anus
voluntary process of placing food into the mouth is referred to as
ingestion
smooth muscle
involuntary muscle found in internal organs, peristalsis
The part of the pharynx that is a passageway for air only is the
nasopharynx
Sections of the pharynx
nasopharynx, oropharynx, laryngopharynx
Segmentation
the division of the body of an organism into a series of similar parts
Peristalsis
the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wavelike movements that push the contents of the canal forward.
