Each flatworm is different in terms of food consumption, but most platyhelminthes absorb nutrients by consuming them through a mouth. Food travels into a gut-type structure that holds and digests it. Once the food is broken down, the digestive system passes it all through the body.Flatworms, bag-shaped but flattened, also get oxygen and nutrients to their body cells easily because all their cells are close to either their outer surface or their digestive cavity (Fig. 3.40 C).Features of the Flatworms
Flatworms have an incomplete digestive system. This means that their digestive tract has just one single opening. Their digestion takes place in their gastrovascular cavity. Flatworms do not possess a respiratory system.

Where is the flatworms digestive system?
Physiological Processes of Flatworms
Most flatworms have an incomplete digestive system with an opening, the “mouth,” that is also used to expel digestive system wastes. Some species also have an anal opening. The gut may be a simple sac or highly branched.
Do flatworms have a digestive system?
Most flatworms, such as the planarian shown in Figure 1, have a gastrovascular cavity rather than a complete digestive system. In such animals, the “mouth” is also used to expel waste materials from the digestive system. Some species also have an anal opening. The gut may be a simple sac or highly branched.
How does a marine flatworm eat?
They feed on tunicates, small crustaceans, worms, and molluscs. These flatworms feed like sea stars, extruding their pharynx, which secretes enzymes to digest their prey.
How does a flatworm eat a crab?
The slender flatworm Euplana gracilis consumes its prey by sucking out their insides.
Do flatworms use intracellular digestion?
Intracellular Digestion
Most animals with soft bodies use this type of digestion, including Platyhelminthes (flatworms), Ctenophora (comb jellies), and Cnidaria (coral, jelly fish, and sea anemones).

Introduction to the Platyhelminthes
Because of the lack of any other body cavity, in larger flatworms the gut is often very highly branched in order to transport food to all parts of the body.
Phylum Platyhelminthes
To ingest (swallow) food, the planarian extends its pharynx out of its mouth. The pharynx is a muscular tube that is used by the planarian to swallow prey …
Which body part does a flatworm first use to catch its prey?
Which body part does a flatworm first use to catch its prey? Pharynx.
Are flatworms decomposers?
Since most flatworms are parasitic in nature, they are mostly responsible for sickness or disease. However, some free-living flatworms do help the environment by acting as decomposers.
What are parasites how do they feed themselves?
Parasites are plants or animals that live in or on another living thing, getting their food from it while it is still alive. The organisms that they live on are called hosts. Hosts never benefit from parasites. In fact, some parasites eventually cause their hosts to die.
What is the pharynx and how does the flatworm use it?
The pharynx is a muscular tube that is used by the planarian to swallow prey animals whole (in the case of small animals) or to suck in body juices of a larger animal.
How do flatworms work?
Flatworms lack a respiratory or circulatory system; these functions take place by absorption through the body wall. Nonparasitic forms have a simple, incomplete gut; even this is lacking in many parasitic species. Movement in some flatworms is controlled by longitudinal, circular, and oblique layers of muscle.

How do parasitic flatworms that lack a digestive system obtain nutrients?
Other types of flatworms are parasitic. That means they live inside another organism, called a host, in order to get the food and energy they need. For example, tapeworms have a head-like area with tiny hooks and suckers (known as the scolex) that help the worm attach to the intestines of an animal host (Figure below).
Where is the mouth of a flatworm?
Flatworms possess a ‘blind gut’, they have a mouth but no opening at the lower end of the alimentary canal through which solid waste is eliminated from the body.
How do nematodes digest food?
Nematoda. Nematodes have a simple digestive tract that includes only a long hollow intestinal cavity that contains only muscles that run vertically down the worms body to aid in simple contraction movement. The food enters the mouth into the pharynx and continues to the anus.
How do flatworms hunt?
The flatworm body is bilateral—the first body plan with that design. As hunters today, flatworms hunt prey with their head leading the way. Flatworms are hermaphrodites: an individual flatworm is both male and female. When flatworms mate, the worm that first receives sperm, carries the fertilized eggs.
Is a flatworm a carnivore?
Planarians are free-living flatworms, and have a much simpler life history. They inhabit freshwater, and are carnivores (even without teeth) or scavengers. Most are less than a centimeter long.
What type of feeder is a parasite?
The filter feeders filter bacteria, algae, protozoans and other bacteria from the water, these. organisms are usually sessile and relatively inactive. The Parasites are small organisms such as. worms. They enter the host in larval form and grow by obtaining food from the host.
What do flatworms use for respiration?
Flatworms have no specialized respiratory system; gases simply diffuse across the body wall.
How do flatworms reproduce?
Flatworms are hermaphroditic (having both male and female sex organs) and they typically reproduce both sexually and asexually. The majority of sexual reproduction is through cross-fertilization (where both individuals fertilize each other).
How do flatworms protect themselves?
Parasitic flatworms protect themselves from the hosts’ digestive liquids by developing teguments or coverings around their bodies.
How do planaria find food?
Planarians ingest food through a tube called the pharynx, which is usually kept inside their body. During feeding, this tube extends out of the planarian’s ventral midsection.

What is intracellular and extracellular digestion?
In intracellular digestion, the breakdown of food materials into small molecules occurs inside the food vacuoles within the cell. In extracellular digestion, the breakdown of food materials into small molecules occurs outside the cell in the lumen of the alimentary canal or on the decaying organic materials.
What is meant by intracellular digestion?
Intracellular digestion can also refer to the process in which animals that lack a digestive tract bring food items into the cell for the purposes of digestion for nutritional needs. This kind of intracellular digestion occurs in many unicellular protozoans, in Pycnogonida, in some molluscs, Cnidaria and Porifera.
