Bile duct, common hepatic duct and cystic duct

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.
