Flatworms

__//**﻿FLATWORMS **//__ __//**Alejandro Rios **//__ __//**Kevin Landau **//__ On Earth, there are worms everywhere around us. Not all of them are long, slimy earthworms that do the same function. They are all characterized differently. These types of characteristics include: One of the many types of worms includes flatworms. Flatworms are the simplest worms, because they are unsegmented unlike others which are segmented. Another reason why they are very simple is that they are no thicker than a few millimeters. The definition of a flatworm is that they are soft, flattened worms that have tissues and internal organ systems. Even thought they are simple they of their few to have three embryonic germ layers (ectoderm, mesoderm, and endoderm), bilateral symmetry, and cephalization. Flatworms are part of the phylum Platyhelminthes. They are also known as acoelomates, which means that they have no coelom. A coelom is a body cavity that is fluid-filled, which is lined up with the mesoderm. The mesoderm is the layer in a tissue which is in the middle. In this type of worm there is coelom, and that there is only a digestive cavity lined up with the endoderm, the section in a tissue which is in the middle. In addition, flatworms are bilateral symmetric animals. This also means that they have two sides of their bodies which well-formed and not deformed, which can be considered as right and left. Flatworm’s bodies are very thin which means that cells are very close to the external environment. This indicates that materials, using diffusion, can pass easily to perform body functions such as respiration and circulation of the blood around the body. Two types of species of flatworms are known as free-living and parasitic flatworms. Free-living flatworms are the most common ones, because they have organ systems for digestion, reproduction, response, and excretion. On the other hand, there are parasitic flatworms which most likely came to be from their free-living ancestors. Parasitic flatworm’s internal organs and other structures were modified or even lost. Commonly parasitic flatworms are simpler than their other side. Flatworms have many functions in their body in order to perform their daily activities and in general, live. When referring to feeding, flatworms are very diverse. They can be carnivores that feed on tiny aquatic animals, but also parasitic. When flatworms are considered carnivores it can also mean that they can be scavengers that feed on dead animals. A typical flatworm, planarian can be considered as an example in which they contain only one opening and mouth in which food and also wastes goes in through. Another important internal structure is the pharynx which is a muscular tube coming out of the mouth which pumps in food into the cavity and then digested through the digestive cavity. The pharynx is used to suck food into the gastrovascualr cavity. During the process of digestion there is also nutrient assumption and all the foods spread out to all the tissues.

 * response
 * respiration
 * circulation
 * excretion
 * movement
 * reproduction.

On the other hand, parasitic flatworms base their feeding on blood, tissue fluids, or pieces of cells within the animal or body they are in, host. Due to the lack of eating like carnivores they have very simple digestive systems and do not need complex digestive systems that are only able to digest fluids such as blood and small cells. Some of these parasitic forms of flatworms have a specific type of pharynx that pumps food into dead-end intestinal sacs which work for digestion. Very few flatworms do not have circulatory systems due to the fact that it is very thin and materials transport in and out of the body very easily. The process they use is diffusion in order to get oxygen and other important nutrients, but also to remove carbon dioxide and wastes. Unlike other types of worms in the world, flatworms have no gills or respiratory organs, heart, blood vessels or blood at all. Flatworms have an excretory system which consists of many excretion tubules and also they contain flame cells on the outside of the tubes. These flame cells are cells that are specifically there to perform the act of removing excess of water from the body, It sort of serves as a filter just like in our bodies and a fish tank. Another function of these very important flam cells is that they remove metabolic wastes, for example, ammonia and urea. When flame cells join together they form a network of tubules which then is connected to the outside environment through small pores in the most upper layer of the animal’s skin. <span style="background-color: #0e0bea; color: #ffffff; font-family: 'Comic Sans MS',cursive; vertical-align: sub;"> <span style="background-color: #0e0bea; color: #ffffff; font-family: 'Times New Roman',serif; font-size: 16px; line-height: 32px; vertical-align: sub;">When relating to the nervous systems of flatworms, they are more complex for responding to their surroundings compared to sponges or cnidarians. Throughout free-living flatworms, the head is the main center of the nervous system and contains most of the nerve cells in the body which are mainly referred to as ganglia. They are as complex as a brain in a human’s body. In contrast, parasitic flatworms do little interaction with their external environment and less of a complex nervous system. Like most animals in this world, flatworms have “eyes” which are also considered to be eyespots that detect change in the amount of light that surrounds them. In addition, they also have cells which detect stimuli, which detect the internal pathways of food such as which way water is flowing. With these ganglia and eyespots they can gather information in order to locate food to find shelter during the day such as under a log or stone. Some flatworms move using cilia in the form of gliding through water and some have muscle cell which are mainly controlled by a network of nerves which also allows them to react quickly to its surroundings such as twisting and turning. In free-living flatworms reproduction takes place sexually, commonly referred to as hermaphrodites and also reproduce asexually through fission. During fission the organism splits in two and each half grows new parts to become a complete functioning organism. <span style="background-color: #00ff68; color: #fa6705; font-family: 'Comic Sans

segments referred to as progolottids and male sexual organs which are called testes. These testes produce sperm which can fertilize eggs of other tapeworms or of the same individual. The organization of the proglottids is that the youngest is at the head and the oldest on the tail. For example, tapeworms can form in a human body when humans eat incompletely cooked meat which contain cysts, which are larvae grow and then go into the muscle tissue, this larvae becomes active. This active stage is when adult worms begin to grow within human’s intestines. Sometimes these tapeworms can grow at a very fast rate and eventually at least a foot. When human release wastes when having this worm inside them, it comes out with the wastes.

category of flatworms. Turbellarians are free-living flatworms which mainly live in marine or aquatic environments. Some familiar flatworms that are in this group include planarians freshwater worms. These worms greatly vary in size, shape, and color. Anotherm group are flukes are members of the Trematoda class. They are parasitic flatworms which infect internal organs of their host. They can live on the outside or inside of their host. The primary hosts are usually a human and there are many other hosts. This group of flatworms can infect humans in very drastic ways such as releasing eggs, clogging up vessels which mainly cause swelling in a disease known as schistosomiasis. This disease is mainly the cause of exposed skin in which this type of flatworm goes in through. Another dangerous type of flatworm are tapeworms which are long, flat, and parasitic worms that adapt their lives into living in their host’s intestines. Their body walls already contain digested food and the mouth has suckers to attach to the intestines.
