  2. 1- Phylum: Porifera Systematic Position: Kingdom: Animalia الحيوانات Subkingdom: Parazoa تحت مملكة نظائر البعديات Phylum: Poriferaشعبة الاسفنجيات (المساميات) ex: Sponges

  3. Sponges are sessile with porous bodies أجسام مساميةand choanocytesالخلايا المطوقة أو المسوطة . • The germ layers الطبقات المنبتةof sponges are not really tissues because the cells are relatively unspecializedغير متخصصة . • Sponges do not have nervous, digestive or muscle systems. • Most sponges are marine بحريةand some live in fresh water. • The body of a sponge consists of two cell layers separated by a gelatinous region, the mesohylالمادة الهلامية. • Most sponges are hermaphroditesخنثي(bisexual) , with each individual producing both sperm and eggs. • The body of a simple sponge resembles a sacيشبه كيس perforated with holesفتحات • All sponges are suspension feedersيتغذى على العوالق collecting food particles from water.

  4. التجويف المركزي الفويهة الفوهة أو المسام • Choanocytes use their flagella to create water currents تيارات مائيةthrough external pores called ostiaفوهات. • Bring food (bacteria, Protists, etc.) and oxygen and remove metabolic wastes from the center of the sponge, spongocoel. • Choanocytes use collar-like rings to filter food. • Wastes and water flow out a central osculum; an excurrent pore. البرعم

  5. Diploblasticaالحيوانات ثنائية الطبقات 2- Phylum: Coelenterata Systematic Position: Kingdom: Animalia مملكة الحيوان Subkingdom: Metazoa تحت مملكة البعديات الحقيقية Phylum: Coelenterata شعبة الجوفمعويات Class: Hydrozoaطائفة الهيدريات Examples: Hydraالهيدرا, Obeliaالأوبليا

  6. This basic body has two Parts: the sessile polypالقرص الجالس and the floating medusaالميدوزا العائمة . • The polyps adhere to the substratum by the aboral end and extend their tentacles, waiting for prey. • Medusas(also called jellies) are flattened, mouth-downالفم لأسفل . • They are carnivoresلاحمthat use tentaclesاللوامسarranged in a ring around the mouth to capture prey and push the food into the gastrovascularالوعاء الجوفمعوي chamber for digestion. • Muscles and nerves exist in their simplest forms.

  7. Hydra sp. • The basic body plan is a sac with a central digestive compartment, the gastrovascular cavity التجويف الجوفمعوي. • Hydra exist only in the polyp form. • When environmental conditions are favorable, a hydra reproduces asexually by buddingالتبرعم

  8. Triploblasticaالحيوانات ثلاثية الطبقات 3- Phylum: Platyhelminthes Systematic Position: Kingdom:Animaliaمملكة الحيوان Subkingdom:Metazoaتحت مملكة البعديات الحقيقية Phylum:Platyhelminthesشعبة المفلطحات 1- Class :Trematodaطائفة التريماتودا example:Schistosoma sp.البلهارسيا (الشيستوسوما) 2- Class:Cestodaطائفة السيستودا example: Taenia sp. (Tapeworms) الدودة الشريطية (التينيا)

  9. Platyhelminthes (Flatworms) الديدان المفلطحة • They are acoelomatesعديمة التجويف السيلومي with gastrovascular cavities تجويف وعائي-معوي • They are living in marine and freshwater. • They also include many parasitic species, such as the flukesديدان البلهارسيا and tapewormsالديدان الشريطية . • Flatworms are triploblasticثلاثية الطبقات , with a middle embryonic tissue layer, mesodermالطبقة الوسطى , which contributes to more complex organs and organs systems and to true muscle tissue.

  10. Schistosoma sp. البلهارسيا • Trematodes parasitizeawide range of hosts, and have complex life cycles with alternation of sexual and asexual stages. • It requires an intermediate host in which the larvaeيرقات develop before infecting the final hosts (human) where the adult worm lives. • The fluke Schistosoma infects 200 million people.
