BIO 3102 Study Guide - Midterm Guide: Cnidocyte, Microvillus, Phagocytosis
Document Summary
Incomplete digestive tract, no end, must ingest and then spit out waste. Digestive enzymes enter gut, then phagocytosis and intracell digest. Particles, bacteria, and single-celled algae are trapped in the microvilla. Mouth connects with incomplete gut that branches throughout the body. Use longitudinal muscles, sine waves, setal hairs used to anchor. Nemotoda anterior valves to suck food in, hydrostatic pressure forces food into stomach muscles unpartitioned body cavity. Tube feet that have circular and longitudinal muscles. They suction to surface, long muscles bend and move org. Solomic cavity with tube feet pass food to eachother and into mouth. Use suction of tube feet to pry open clams (squirt digestive juices and suck in meat) Traps food in lophophore, which passes it down into the mouth. Crawl using fleshy appendage and circular and longitudinal muscles. Pentaradial symmetry for more arms to trap food.
