Document Summary
Transport: short distance transport: transports water and solutes from cell to cell at level of tissues and organs. Long distance transport: transport within the xylem and phloem at the level of the whole plant: proton pump: moves h+ ions out of cell while hydrolyzing atp for energy (active). Flame cells function like a kidney, removing waste materials: scolex: the anterior end of a tapeworm, bearing suckers and hooks for attachment. Incurrent/excurrent siphon: openings found in tunicates allowing water and waste to enter/exit: tissue (4 types): epithelial, connective, muscular, nervous, epithelial tissue: covers body or lines cavity; responsible for protection, absorption, secretion or. Synapses: neurons communicate at these junctions: harversian channel: microscopic channel where nerves in the bone tissue run through the capillaries. Lacuna: where chondrocytes in cartilage lie either alone, in groups of 2 or in groups of 4 in an unfilled gap space.
