Biology of worms

The worms

The worms are multi cellular eukaryotic organisms with digestive, circulatory, neurological, reticular and reproductive organs. Parasite worms are devoted to living inside a superb host body. In contrast to non-parasite species, the following traits can be noted:

1. The digestive tract has gone undetected and the food is absorbed from food, body fluids and host tissues.

2. The nervous system has been degraded. These organisms do not require advanced nervous system because they do not need to seek food or compromise on the environment, and the conditions in which they are present are relatively constant.

3. The movement has been destroyed or completely lost. These animals are from hosts to other hosts and do not need to find suitable habitats.

4. The reproductive system is often more complicated and generates a large number of eggs and contaminates the host with their help.


Mature worms may have two legs, meaning male reproductive organs in one person and reproductive organs in the other person. In these species, reproduction depends on two adult males of the opposite sex in a common host. Adult molds may be hermaphrodite, meaning that any worm contains male and female sex organs. The two Hermaphrodite worms may mate and simultaneously split each other. Few Hermaphrodites are able to fertilize themselves

life cycle:

The life cycle of worm worms may be extremely complicated and will run on consecutive hosts. The term “host” has been given to the body that has sexually matured and sexually explicit. One or more host interfaces may be necessary for the laryngeal stage or developmental stages of the parasite

Wide worms:

Wide worms
The worms belong to this group and are flattened behind the back. Such worms have a defective digestive system, and there is only one mouth through which food enters excrement. Parasitic broadening worms include trematodes and cestodes


The body of the trematodes is flat and leafy and has an abdominal sucker body and an oral organ. The sucking organs are used to keep the living at the base of sucking fluids from the host body. Broad wools also absorb their food through the absorption of their lifeless outer coating called cuticle. On invasive tissue, the host is known to host mature worms (such as worm worms, liver worms, and blood worms). The life cycle of a broad-leaved worm is simply considered to be a wormhole. The adult mold in the echinoderm has a human body or mammals. Its size is about 6 mm wide and 12 mm long. Mature worms Hermaphrodite emit their eggs in the rhizomes. Flowers are usually excreted through feces. (Sputum is usually swallowed and the worms get stool)
Eggs should be introduced into the water to continue the life cycle. Within the eggs, the larvae of Mirceidal can be grown with mirosidium. Then, from the development of the eggs, the larvae enter the snail. Only some species of aquatic snails have the role of intermediate hosts. In the body of the snail, the worm produces non-sexual produce and produces redia. Each form of redia is Cercaria develops and pierces the body of the snail and penetrates the caviar of the crayfish. Celticus is ingested. By eating crab, meta-ulcers eventually penetrate into the lungs and enter the lids in the form of a full-grown worm Coming.
Laboratory diagnosis is based on microscopic examination of phlegm and feces and egg retrieval. Pollution from unsheltered crabs can be avoided by preventing the crab from cooking. Bloodworm spongiform encephalopathy (schistosum) does not enter the body through the mouth, but piercing the human skin and entering the circulatory system. Adult molds are found in the veins of the pelvic and intestinal tract. The problem of schistosomiasis in terms of global health A major consideration.


Cystoda or worms are intestinal parasites. The head or scollex region has suckers and small hooks for binding to the intestinal mucus. The striped hair does not eat the host tissues but it absorbs the food by absorbing the small intestine through the path The cake is made up of parts called proglutins. Premature proglottides are produced by the scollex neck region, and each progloid has male and female organs. The smallest progestogens are mature than the skeletal. The contents of the eggs are fertilized. The progloids are permanently attached to the scollex until it is alive. Is formed.
