Organ What is the organ’s function in the digestive system?
Mouth Food is impasto in the oral cavity the measures of the tongue and teeth
and mixed with salivary gland excretions, which involve enzymes that aim
to moulder carbohydrates
Pharynx The role of pharynx is as piece of the alimentary canal and as an airway in
the higher respiratory system. Muscles of pharynx contract, tongue lift
against surface of mouth, epiglottis closes over glottis, thus closing off
airway.
Oesophagus Peristatic waves in the oesophagus require the food lump (bolus) across
the stomach as a piece of the operation of ingesting.
Stomach Forward with supplying food storage, the stomach moulder absorbed food
into chyme, both chemically along with release acids and enzymes that
shape the abdominal juice released by the stomach mucosa. Also,
mechanically and by the action of stomach muscles.
Small It has a pivotal function in chemical digestion and the intake of ions,
intestine water, and nutrients. At the pyloric end of the stomach the acidity of the
chyme issues the pyloric sphincter muscle to ease. Chyme, in little
quantities, can across into the duodenum.
Duodenum Chyme moves from the stomach to the duodenum across the pyloric
sphincter.
Jejunum The jejunum is more vascular, thicker, and of a heavy colour than the
ileum, and villi larger than in the ileum and large circular folds of
submucosa called plicae circulars.
Ileum It has thinner walls and few fold circulars that are small and vanish
gradually and less vascular than those of the jejunum
Large Large intestine collects some water and food, minerals, and vitamins from
intestine the small intestine. Any of this liquid that it does not ingest it removes as
solid waste. Solid waste is tentatively stored in the rectum before being
moved through its peaked end in the anal canal.

Rectum When the depressor part of the rectum is reduced, its mucous membrane
shapes linear folds that stop solid waste from drive across the anal canal,
so it is promote a sensibility that elicits the urge to motion.
Anus It is essential role being to tentatively store solid waste that is ready to be
rejected from the body.
Pancreas The blend of digestive electrolytes, enzymes, and water called pancreatic
juice, produced in acinar and epithelial cells, exhaustion into the
pancreatic channel which supply crossly from the tail toward the head.
Liver Exocrine secretion (bile) in the liver smoothers the assimilation of lipids
and the removal of overflowing cholesterol from the blood. Deoxygenated
blood clears out the liver in the hepatic vein. Hepatocytes produce bile
that enters canaliculi and travel to the gall bladder. Its reservoir in the gall
bladder while required. oxygenated blood get in the liver from the hepatic
artery and nutrient-wealthy blood from the ileum gets in the liver by the
hepatic portal vein.
Also, the liver stores glycogen to help regulate blood glucose rate, makes
plasma proteins, stores fat-soluble vitamins such as vitamin A and
metabolites drugs, alcohol, and different toxins. It breaks down waste
amino acids to produce urea for removal at the kidneys.
Gall bladder The bile is about 10 cm long and it is a thin-walled green muscular sac,
snuggled into a depression on the ventral surface of the liver. The bile is
produced by the liver stir out of the common hepatic channel across the
common bile channel into the duodenum; when the sphincter of Oddi is
sealed, the bile is stored and reduced in the expandable gall bladder.

Function of the digestive system
Whereas food is in the gut in the lumen area, it is still outside of the body suitable.
Big molecules afford hydrolysis and are digested to tiny molecules that can be take in
across the gut wall to the bloodstream for use in the body. absorption is where
digested food molecules travel into the cells of the body to be used.
