Sixth unit of first year's Zoology, that is, biology and human welfare. In that lesson, today we are going to discuss about ascarus lumry coitus is a parasite. Okay, that is ascarus, ascarus lumry coitus. Ascarus lumry coitus, lumry coitus that is goes to peritamin, anglidin organisms is goes to lumry coitus, the recidisamble organism, that is what we call as lumry coitus. Classification is goes to phylum, phylum, nimaachoda, phylum, nimaachoda, class, fast media, class, fast media. Okay, ascarus lumry coitus phylum belongs to nimaachoda and the class belongs to fast media, it is commonly called as roundworm. Comerly called as roundworm, it is cosmopolitan distributions. It is spread throughout the world, that is why we call as cosmopolitan, cosmopolitan indistribution. It is cosmopolitan distributions. Basically, it is infected to the human beings, it is only the complete life cycle in only single host we call as monogenetic parasite, monogenetic parasite, monogenetic parasite, and also, these are cosmopolitan distributions, monogenetic parasite, it is goes to pseudo-seelom, pseudo-seelomate, it is pseudo-seelomate mostly infected to the human beings, especially with the childrens, especially the childrens is highly infected. Next, it is the di-genetic parasite, ascarus lumry coitus a di-genetic parasite, means sexually there are two organisms, male and female differentiation, represents. That is why we call as a di-genetic parasite, di-genetic parasite, di-genetic parasite means male or female will be differentiation we call as di-genetic parasite. Let us go to structure, structure of parasite, structure of parasite. The ascarus normally goes to cylindrical body, cylindrical body, it is and drawing the organism is goes to male one, it is male one, until the part that is a half a three lips will be there, three lips will be there, the center there is a half a mouth is located, mouth is located, just beneath of the mouth area the small pore we call as excretory pore, excretory pore is presence and a digital part of the tail is goes to coiled one, here there is a half a equal panel ct, equal panel ct will be there, here there is a half a small aperture, this is cloye-cal, cloye-cal aperture, cloye-cal aperture will be there, okay this is a male one and similarly this goes to female one also just longer than the male one, the same cylindrical of the body, same cylindrical of the body, same cylindrical of the body, until there is a half a mouth, it is a mouth and just to be low off is goes to excretory pore and just three by four portions there is a half a genital pore is goes to female genital pore, female genital pore, just behind of the tip of the tail there is a half a mouth, mental side one more pore will be there, that is goes to excretory, it goes to anus will be there,
