Project: Urine Formation Diagram
OBJECTIVE:
To illuminate the processes on pressure filtration, selective reabsorption, and tubular excretion by showing the movement of all components across the capillary and tubule walls, indicating whether each component moves by osmosis, diffusion or active transport.
GUIDELINES:
All visuals must be original and hand drawn.
Drawn in pencil, then outlined in coloured markers or pencil crayons.
INSTRUCTIONS:
Separate the page into 6 sections (as shown) to reflect regions of the nephron. Label each section accordingly.
Glomerulus/             Peritubular Capillary Network/    Peritubular Capillary Network/
Bowman's space/       Interstitial fluid/ Proximal          Network/ Interstitial fluid/
Bowman's Capsule    Convoluted Tubule                      Descending Loop of Henle


Peritubular Capillary Network/ Peritubular Capillary Network/ Renal Venule/
Interstitial fluid/                         Interstitial fluid/                         Interstitial fluid/
Ascending Loop of Henle          Distal Convoluted Tubule          Collecting Duct

In each region (when relevant),
Show the movement of the following substances: water, nitrogenous waste (urea, uric acid), salts (Na*, C1, K*), H*, nutrients (glucose, amino acids), creatinine, penicillin and drugs
Make sure to include blood cells, platelets and plasma proteins where appropriate
Use a legend to indicate whether the movement of the above substances is by osmosis, diffusion or active transport, pressure
Clearly label the processes of pressure filtration, selective reabsorption, and tubular excretion wherever they occur.
Identify the locations affected by ADH and aldosterone, and explain/show their effect(s)
In the final section, list the main components of the urine/filtrate in the collecting duct and the main components of the blood in the renal venule
Before submitting, self-evaluate your work using the criteria sheet on the back side of this handout and then staple it to the front of your project.
Remember, this assignment is for your benefit and to help you understand the steps of urine formation.
