a)
outline the flow of filtrate through the nephron.
b) outline the flow of blood through the nephron.
c) describe the properties of the ultrafiltrate of
plasma
(Please be neat when labeling the sketch)
Describe the flow of fluid through a nephron and to the external
environment. Include a simple labelled sketch with your
description
Trace the pathway of urine formation from the
nephron/collecting duct until urine leaves the body through the
urethra. Be sure to include all structures urine passes before it
exits at the external urethral orifice. Note the differences in the
male and female urethra.
Draw and label the parts of the uriniferous tubule. Include all
parts of the nephron and the collecting duct. List the sequence of
filtrate moving through the nephron to collecting duct in the
correct sequence.
Outline and diagram the effects of Vasopressin (ADH) on the
nephron, and how it promotes water conservation in the kidneys. Be
sure to EXPLAIN the cellular mechanisms of action.

Describe the order of blood flow through the nephron in
order and explain each step of the pathway-
afferent arteriole, glomerulus, efferent arteriole, peritubular
capillaries, vasa recta
Doubly‑charged calcium ions, Ca 2 + , are released into your
bloodstream and flow through your capillaries. The diameter of a
capillary is about 8.90 μm, calcium ion concentrations are
approximately 1.10 mol/m 3 , and typical electric current flow due
to the Ca 2 + ions is around 1.2 nA. Calculate the drift speed v
drift of the calcium ions. v drift = m/s
