Digestive System and Organs
The digestive has a massive part in nutrition. Food is broken down by
the digestive system into nutrients like proteins, lipids, and carbs.
The body can utilise them for energy, growth, and repair after they
are absorbed into the bloodstream.
,The human body depends on its primary internal organs to carry out
a number of essential duties in order to survive and procreate. A
bodily system is made up of component pieces that are formed when
two or more organs and the structures they are connected to
function together.
Organ Function Location
Mouth When you chew, the Skull
(Amylase produced to break digestive process begins in
down dense carbs) your mouth. Saliva is a
digestive juice produced by
your salivary glands that
helps food pass more
readily past your
oesophagus and into your
stomach by moistening it.
Additionally, saliva contains
an enzyme that starts to
break down the starches in
food.
Pharynx Transports liquid and food Behind the nose,
to the digestive system.
Prevents food from being down the neck,
inhaled by forcing it into the placed at the top of
oesophagus. Drains fluid the trachea and
from the ears and balances
pressure inside them. oesophagus
Oesophagus The oesophagus main job is Above diaphragm in
to carry food from the
mouth through to the chest
throat and into the
stomach. After a few taste
buds on the organ,
that function begins at
the beginning of the
oesophagus.
Stomach An muscular hollow organ, Upper abdomen, left
the stomach. It takes food
from the oesophagus (food side of the body
pipe) and mixes and digests
it before transferring little
amounts of it to the small
intestine.
Small Intestine The duodenum, jejunum, Lower abdomen,
, (duodenum, jejunum and and ileum are the three beneath stomach
ileum) sections of the small
intestine. It aids in the
further digestion of
stomach-born meals. It
takes in water, vitamins,
minerals, carbs, lipids, and
proteins from food so that
the body can utilise them.
The digestive system

Gall Bladder Bile from the liver is stored Underneath liver
and concentrated in the
gallbladder. The bile is
subsequently expelled into
the duodenum, the first part
of the small intestine, where
it aids in the digestion and
absorption of lipids from
food.
Liver The liver is a multi- Beneath ribcage,
