3. WHAT IS DIGESTIVE SYSTEM?
The process of mechanically and enzymatically breaking down food into
substances for absorption into the bloodstream. The food contains three
macronutrients that require digestion before they can be absorbed: fats, carbohydrates,
and proteins.

5. LIVER
The liver is the largest solid organ in the body. It removes
toxins from the body's blood supply, maintains healthy blood sugar
levels, regulates blood clotting, and performs hundreds of other vital
functions. It is located beneath the rib cage in the right upper
abdomen.
6. An organ that is part of
the digestive system. The
stomach helps digest food by
mixing it with digestive
juices and churning it into a
thin liquid.
STOMACH PANCREAS
The pancreas has digestive
and hormonal functions: The
enzymes secreted by the
exocrine gland in the pancreas
help break down carbohydrates,
fats, proteins, and acids in the
duodenum. These enzymes
travel down the pancreatic duct
into the bile duct in an inactive
form. When they enter the
duodenum, they are activated
7. DUODENUM
The duodenum is the first
part of the small intestine. It is
located between the stomach and
the middle part of the small
intestine, or jejunum. After foods
mix with stomach acid, they
move into the duodenum, where
they mix with bile from the
gallbladder and digestive juices
from the pancreas.
8. RIGHT COLIC FLEXURE
Also called the
hepatic flexure,
consists of a curve at
the junction with the
transverse colon. A
peritoneal fold
extending from the
hepatorenal ligament
most likely supports
this portion of the
large intestine.
Bend in the large
intestine in the left upper
quadrant of the abdomen as
the transverse colon
continues as the descending
colon
LEFT COLIC FLEXURE
9. ASCENDING COLON
A segment of the large intestine that
passes horizontally across the abdomen
and sits beneath other organs in the
abdominal cavity.
TRANSVERSE COLON
The ascending colon
lies on the right side of
the abdominal cavity, in
front of the quadratus
lumborum and
transversus abdominis
muscle
DESCENDING COLON
Section of the large
intestine. It is the left part
of the colon that passes
downward.
10. TENIAE COLI
The teniae coli are
three separate longitudinal
ribbons of smooth muscle
on the outside of the
ascending, transverse,
descending and sigmoid
colons. They are visible and
can be seen just below the
serosa or fibrosa
A pouch that forms the first
part of the large intestine. It
connects the small intestine to
the colon, which is part of the
large intestine.
CECUM
The middle part of the
small intestine. It is between
the duodenum (first part of
the small intestine) and the
ileum (last part of the small
intestine). The jejunum helps
to further digest food coming
from the stomach.
JEJUNUM
11. APPENDIX
The S-shaped section of
the colon that connects to
the rectum. The distal colon
includes the descending
colon and the sigmoid
colon.
The appendix is
a small, thin pouch
about 5 to 10cm (2
to 4 inches) long.
It's connected to
the large intestine,
where poo forms.
Nobody knows
exactly what the
appendix does, but
removing it is not
harmful.
SIGMOID COLON RECTUM ANUS
The rectum is the end
part of the large intestine
that connects the colon to
the anus. It is the area
where a person holds stool
before excreting it from the
body.
The anus is the
opening at the lower
end of the intestines.
It's where the end of
the intestines connect
to the outside of the
body. As food is
digested, it passes from
the stomach to the
small intestine. It then
moves from the small
intestine into the main
part of the large
intestine (called the
colon).
