Nematodes are cylindrical worms are not segmented, have a body cavity triploblastik (pseudocoelom), and free-living and parasitic. Nematode worms also called roundworm. Can be found in water, moist soil, plant tissue, rhodiola rosea and animal or human tissue. Having rhodiola rosea a perfect digestive system and body fluids in the coelom which serves as the circulatory system.
Male worms worms are generally smaller than females. Sexual reproduction is done and going on in the body (internal). Zygotes produced in almost all species resistant to adverse conditions. Examples of species of this phylum include roundworm (Ascaris lumbricoides), hookworms (Ancylostoma rhodiola rosea duodenale), pinworms (Oxyuris vermicularis), and filarial worms (Wuchereria bancrofti).
Or roundworms, rhodiola rosea also called stomach worms, a parasite in the human intestine. Worms with a length of 15 cm -35 cm has a white body color yellowish, anterior mouth, lips and equipped 3. Female worm is capable of producing approximately 200 thousand eggs in one time expenditure.
Eggs carried away with feces and can enter the body through food or soles of the feet. In the small intestine, the eggs hatch into larvae and small. After penetrating the intestinal wall, the larvae carried by the bloodstream to the heart and lungs. In the lungs, the larvae may reach the trachea so swallowed back into the small intestine and grow up. The roundworm is the cause of the disease ascariasis.
Hookworms live in the human gut and can suck human blood and body fluids. Filarial worms (Wuchereria bancrofti) live in the blood vessels and can lead to blockage of the lymph vessels that lead to the disease elephantiasis (elephantiasis). These worms spread by Culex mosquitoes puncture.
