BIOL10002 Lecture Notes - Lecture 17: Respiratory Center, Osmosis, Intercostal Muscle
Document Summary
Regulation of respiration: respiratory organs gills (structure, highly folded increased surface area, specialized cover operculum, pumping mechanism moves water over gills. Water follows by osmosis, and moist thin mucus allows cilia to beat and sweep away foreign particles, including bacteria: cystic fibrosis, lack of cl- channel causes a thick, viscous mucus to form. Increased bpg increase o2 release from haemoglobin: anaerobic metabolic pathways, long-term, reset the threshold, erythropoietin acts on bone marrow to produce more rbc. Increase the number of rbc and blood hb content. Reading from life (11th edition), chapter 48: respiratory gas exchange is governed by physical factors, enhancing diffusion maximises respiratory gas exchange, humans have tidal respiration, respiratory gasses are transported via the blood.
