Trichinella spiralis
Stayin' Alive
Acquiring nutrients is
very simple in these organisms because they are parasitic.
When these organisms are ingested, they begin to develop and
travel until they arrive in the bloodstream.
Within the blood stream there are tons of nutrients that
these organisms can utilize, such as sugars, lipids,
proteins, and carbohydrates.
In simplest terms, these
organisms steal whatever nutrients their hosts have acquired.
They accomplish this through the use of their buccal cavity
in the uptake of nutrients from the bloodstream.
When the nutrients have been ingested through the buccal
cavity, they travel through the digestive system of
these organisms. These organisms are small enough that they
don’t need a circulatory system to supply their tissues with
nutrients because all of the cells of these organisms
get sufficient nutrients through simple diffusion across
their membranes. The nutrients left over after absorption
are excreted from the body through the rectum.
