What organ is organ X in the
diagram?
This diagram shows several of the
organs that are involved in the human digestive system. Let’s have a go at labeling some of
these organs so we can work out what the organ labeled X is.
At the bottom of the image, we can
see part of the duodenum, which is the first section of the small intestine. The small intestine is the site of
digestion of lipids, carbohydrates, and proteins into their constituent subunits,
which can then be absorbed across the small intestine wall to be transported to the
cells that require them.
The pancreas is visible in this
diagram, located next to the duodenum. One of the functions of the
pancreas is to secrete digestive enzymes directly into the duodenum to help break
down the lipids, carbohydrates, and proteins that pass through the small
intestine.
The gallbladder is the small green
organ, partially hidden by organ X. The gallbladder stores bile and
secretes it into the duodenum to aid in lipid digestion. The organ responsible for producing
this bile, among multitudes of other functions, is the liver.
The liver is the large organ that
has been labeled on this diagram with an X. So, we can confirm that organ X is
the liver.
