Biology of Organisms Tutorial 3

...Tutorial 3 Bio 207 1) Glomerular filtration rate (gfr) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the tiny filters in the kidneys each minute. These tiny filters are called glomeruli. Vasa recta is the hairpin shaped capillaries that serve the long loop of henle of juxtamedullary nephrons. Each ascending porion of the vasa recta lies next to the descending portion of a loop of henle and vice versa Although the loop of henle and the vasa recta do not exchange materials directly, they function together as a counterpart of a countercurrent system that enhances nephron efficiency. (source Campbell, Reece, et al., Biology 8th edition. 2009. Renal clearance is a measurement that allows one to analyze the activity of the kidney. Renal clearance = urine concentration (M) x urine flow rate (ml/min)/plasma concentration (M)= UV/P RCGFR=secretion RC=GFR = nothing is secreted or absorbed. (source: www.austince.edu/emeyerthclearancehtm.htm) Single effect is produced by the use of metabolic energy between adjacent parts of the two oppositely flowing fluid streams in a counter current multiplier system (Source: Hill, Wyse and Anderson, Animal Physiology 2012) 2) Blood enters the kidneys through the bowman’s capsule where it enters a cluster of blood capillaries called the glomerulus. Fluid is driven through a filter in the glomerulus into the capsule’s lumen by the hydrostatic pressure of the blood. The fluid that...

Peer Tutoring and the Conversation of Mankind.Doc

...87 .,~. Peer Tutoring and the "Conversation of Mankind" by Kenneth A. Bruffee The beginnings of peer tutoring lie in practice, not in theory. A decade or so ago, faculty and administrators in a few institutions around the country became aware that, increasingly, students entering college had difficulty doing as well in academic studies as their abilities suggested they should be able to do. Some of these students were in many ways poorly prepared academically. Many more of them, however, had on paper excellent secondary preparation. The common denominator among the poorly prepared and the apparently well prepared seemed to be that, for cultural reasons we may not yet fully under­ stand, all these students had difficulty adapting to the traditional or "normal" conventions of the college classroom. One symptom of the difficulty was that many of these students refuSed .help when it was offered. Mainly, colleges offered ancillary programs staffed by professionals. Students avoided them in droves. Many solutions to this problem were suggested and tried, from mandated programs to sink-or-swim. One idea that seemed at the time among the most exotic and unlikely (that is, in the jargon of the Sixties, among the most "radical") turned out to work rather well. Some of us had guessed that students were refusing the help we were providing because it seemed to them merely an extension of the work, the expectations, and above all the social structure of traditional classroom learning. And...
