Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.

What characteristic is shared by cnidarians and flatworms?
a digestive system with a single opening
Why is a blood system unnecessary in either free-living or parasitic flatworms?
Flatworms, both free-living and parasitic, lack a blood system because they have a flat body structure that allows for efficient diffusion of nutrients and gases directly through their skin. Their bodies are thin enough that all cells are close to the external environment, facilitating the exchange of oxygen and waste without the need for a circulatory system. Additionally, many parasitic flatworms absorb nutrients directly from their host, reducing the need for an internal transport system.
How many opens do a flat worm have?
Flatworms have one opening that serves both as a mouth and an anus, which is part of their gastrovascular cavity. This single opening allows for the ingestion of food and the expulsion of waste. Unlike more complex organisms, flatworms have a relatively simple digestive system.
What is a digestive system with only one opening called?
A digestive system with only one opening is called an incomplete digestive tract. Organisms with this type of digestive system ingest food and eject waste through their mouth.
Does a planarian have a one way digestive system?
The gut is lined with a single layer of endodermal cells which absorb and digest food.
Does a planarian have a one way or two way digestive system?
Planarians are classified underneath the flatworm phyla, and flatworms have two way digestive systems.
How do tapeworms feed if they have no digestive systems?
Tapeworms are parasitic; they don't have need a digestive system because they absorb the nutrients they need from their host(s).
Does a jellyfish have a simple or complex digestive system?
Jellyfish have a simple digestive system. They have a digestive cavity with cells lining the wall that carry out the digestive function.
How are parasitic flukes able to live when they no longer posses a well developed digestive system?
Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.
How are the three platids different from one another?
The three platids, or groups of organisms within the broader category of platyhelminths (flatworms), are differentiated primarily by their habitat, morphology, and reproductive strategies. Turbellarians are primarily free-living and aquatic, characterized by a ciliated body surface. Trematodes, or flukes, are parasitic and often have complex life cycles involving multiple hosts, while cestodes, or tapeworms, are also parasitic but lack a digestive system, absorbing nutrients directly from their host's intestines. These differences reflect their adaptations to diverse environments and lifestyles.
