Hint: Dorsoventral word is made up of two small words. These are dorsum and venter. The word dorsum means the lower part of the body of any object which is being observed whereas the word venter means the front part of a body of any object which is being observed.

Complete answer:
Dorsoventrally flattened body means the body that is flat from the lower as well as the upper surfaces. When any organ of a plant or an animal is compressed along its upper and lower side, then it is known as a Dorsoventrally flattened body. Such a type of animal or plant shows very good length as well as breadth but it does not have much thickness.

This kind of body is usually found in flatworms. Flatworms are the type of organisms that are straight dorsoventrally stretching from their head to tail. They also have a smooth dorsoventrally flattened body. These types of organisms are triploblastic, which means that they have three germ layers, namely, the exoderm, endoderm and mesoderm.

Flatworms are the other name that is given to Platyhelminthes. They are also referred to as tapeworms. They are further classified under invertebrates as they are considered to be devoid of vertebral columns. Such organisms live as parasites on other organisms' bodies including humans. Certain types of animals that are a part of this phylum are considered to be the main reason for causing specific diseases in humans.

Note: Platyhelminthes, also known as flatworms, are invertebrates because they are devoid of vertebral columns. They are also known as flatworms because they have a flat body structure. They have an unsegmented body which is very delicate in nature.
