Such animals are called acoelomates (Fig. 10.3). In acoelomates the gut is sac-type and there • is no special transport system. Only excretory system is developed for the transport of excretory • endoderm. It forms a packing around the internal organs of the animals to support and protect • products. This system consists of lame cells, excretory ducts and excretory pores. However the • In phylum Platyhelminthes there is no body cavity or coelom, and the mesoderm forms a loose, • cellular tissue called mesenchyma or parenchyma which ills the space between the ectoderm and • nervous system is well developed. • Pseudocoelomates • from the blastocoel of the embryo and it is bounded externally by the muscles and internally by the • In Aschelminthes the space between the body wall and the digestive tube is called pseudocoelom • (false body cavity). Pseudocoelom is not homologous to true coelom because: it is not lined by • coelomic epithelium. It has no relation with the reproductive and excretory organs. It develops • cuticle of the intestine. The animals having pseudocoelom are called pseudocoelomates • Coelomates • layer which covers the alimentary canal and the cavity between them is the true coelom. It is filled • The mesoderm splits into outer parietal layer which under lines the body wall and the visceral • with fluid called coelomic fluid. The animals which possess coelom or true body cavity are called Coelom is cavity present between the body wall and the alimentary canal and is lined by mesoderm. • coelomates e.g. animals from annelids to chordates. • • About This Channel..................... • I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. • One-stop destination for all biology lectures. • _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial • _ The videos are categories under various heading to make the students life simplified • Visit My Other Channel Playlist ..................... • NMDCAT PART 1: • New 1st Year Biology • NMDCAT PART 2: • New 2nd Year Biology • Class 11th Lectures: • New 1st Year Biology • Class 12th Lectures: • New 2nd Year Biology • Class 10th Lectures: • • Matric Biology • Subscribe My Channel: • / aliacademya7r • Social Link........................ • Instagram: • https://instagram.com/ranaalibiologis...
