BIO202H5 Lecture Notes - Lecture 5: Countercurrent Exchange, Fluid Compartments, Symporter
Document Summary
Term test 1 labeling will be based on structure not physiology but may ask you in which direction blood or water is flowing. For short answer you will be provided with like 5 words and must be able to connect them to explain the concept. Amphibious marine vertebrates having k co-transporters in the boundary b/w body and external env (ie opeing to lumen aka snorting thing seen in video) Potassium co-transporters (na out of ecf into icf and then into lumen) By salt nasal glands eliminate excess salt. Ecf extracellular fluids, includes all fluids that space b/w cells and space. To pull out ions from ecf to space of wall try to build up concentration of ions in ecf to then be able to eliminate them and pass them through internal env. Na is pulled out of ecf between blood. Fluid in all cytocells in all cells in body = intracellular fluid.
