Document Summary

Name the main functions of the urinary system. As a result, larger solutes are left behind. For instance, a decrease in blood flow and glomerular bp results in afferent arteriole dilation and efferent constriction. Gfr central regulation is carried out if autoregulation doesn"t work. It involves the central regulation by endocrine (renin-angiotensin system) and autonomic ns means. For instance, a drop in bp leads to sympathetic activation then widespread vasoconstriction: identify where countercurrent multiplication takes place and describe the processes that drive it, it takes place in the thin descending limb and thick ascending limb. The thick ascending limb is permeable to solute but impermeable to water whereas the thin part of the descending limb is permeable to water but not solute. The driving factor behind countercurrent multiplication is the active transport of ions out of the thick part of the ascending limb (sets up a concentration gradient).
