Animal Diversity
Nematodes are commonly known as roundworms. They are free-living, very tiny organisms. They have an elongated and tubular body. These organisms have a nervous system and are mostly act as parasites to both animals and plants.
Platyhelminthes
Platyhelminthes are also known as "flatworms" because as they are dorsoventrally flattened from head to tail. They are invertebrate, soft-bodied, acoelomate, unsegmented and have bilateral symmetry.

- Provide a labelled picture which demonstrates the six cardinal planes in human anatomy.Write a long response that thoroughly explores examples of structure and function working together at the following levels in the interest of maintaining homeostasis: A – Organ B – Organ System C – Organism Be specific at each level of organization while keeping the greater good of the whole body in mind. If there was significant dysfunction at the organ level, predict how the effects of that flaw might ripple though higher levels of organization mentioned above? How might this affect the overall health of the person?Which two body systems are charged with maintaining homeostasis by responding to changes in the environment? Answer:
