What are the parasites in the human body

summary

Human parasite refers to the parasite with human as host. It can be divided into internal parasites and external parasites. Most of them belong to protozoa, linear animal, flat animal, Annelida and arthropod. Let's share with you the knowledge about which parasites exist in the human body.

What are the parasites in the human body

First: among the parasites living in human body, ocular filariae is not the most dangerous. The reason why this West African parasite ranks first among the top ten human parasites is that it has a creepy habit of crawling into the eyes of the host.

Second: canine tapeworm, which is a small tapeworm that infects dogs, but they can also enter the human body. The common source of infection is sheep. After the sheep infected with canine Taenia are slaughtered, the taenia cyst in the liver is eaten by the dog along with the sheep's viscera. In the new host, the taenia larvae break out of the cyst, attach to the dog's small intestine wall, and grow into worms.

Third: Guinea worm, also known as guinea worm, is another parasite with an ugly head. The adult can grow up to 78 cm. The larvae of Dracunculus medinalis infect some aquatic crustaceans, such as water fleas, which usually live in dead pools. When people drink the unclean water without knowing it, the water fleas are digested in the body and release the larvae of Dracunculus medinalis, which are parasitic in the water fleas. A few months after infecting the human body, the male and female of Dracunculus medinalis mate, the male dies and is digested by the human body, while the female moves to the legs and feet.

matters needing attention

Parasites are usually eaten in. Some larval cysticercosis are also distributed in the lung, subcutaneous, and even brain eye. Parasites are harmful to the human body, the damage to the human body is mostly plundering nutrition, causing inflammation, blocking blood vessels and so on. Most of them belong to protozoa, linear animal, flat animal, Annelida and arthropod. In parasitology, protozoa are called protozoa, and linear and flat animals are called helminthes. The most important species of internal parasites are protozoa, Nematoda, trematode and tapeworm.
