Intestinal Parasites And Their Dangers
As mentioned previously, there are a lot of parasites. Some of them live in the human body. Among some of the species of parasites living in human, one of the dangerous and harmful ones is intestinal parasites.
The intestinal parasites, as the name implies live inside or near the intestine, they usually feed upon the different nutrients that are present in the intestine, and use them for their growth and life.
Intestinal Parasites get in your body, and start feeding off your body. They are present internally, and though initially are very microscopic in size, as time progresses the parasites that live in humans can essentially grow with the help of the energy present in the body, up to a few cm on average.
The effects can range from Diarrhea, Nausea, Respiratory and Liver problems, to Death.
The cure is usually to take medicines that wipe out such parasites from the body after a doctor prescribes you to them. And then, after they are dead, they will be automatically excreted out just like other intestinal waste products.
But then again, the only way you can cure intestinal worms is first actually identifying them, and that can only be done by first finding that a parasite is living in your body, and that can only be done by first studying the different symptoms that are present in a human body that a parasite is living in.
Either they can be intracellular or intracellular parasites, either way they are dangerous and harmful for the human body if they are living in humans.
Therefore, naturally the human body has natural protections that prevent attack from many of the parasites that try to invade the body. Of course, they aren’t fool-proof, and that’s the reason why Malaria and some intestinal worms can enter the human body. But that’s quite reasonable considering the thousands of species of parasites that are present.
The first layer of protection against Parasites is the human skin itself. The human skin acts as a physical barrier between any invading parasite and the human body. The skin is lined up with dead cells containing the protein keratin which makes skin hard and dry. As most of the parasites need water to survive, they essentially die out when there’s no water present. Similarly a chemical present in the skin “cebum” is toxic to many of the invading parasites.
The mouth and stomach also act as strong barriers for the entry of invading parasites. The mouth contains saliva and Iysozime which prevents entry of any foreign parasite successfully. Similarly, the acidic conditions of the stomach are not suitable for most of the parasites to survive.
Lastly, the immune system is the final step taken to get rid of parasites living on humans. The immune system detects any foreign parasite or germs, and thereby activates the lymphocytes which successfully get rid of the foreign invader.
