Lab Activities
A list of words is provided below that you are expected to identify, learn, and label on the models provided. Note that not all models will have some of the organs/structures, so be sure to find them on an alternate model. You must use all the words provided. Using the colored tape provided, write the number that corresponds to the organ/structure and place them on your model. When complete, notify your TA so they may check your work.
For each additional station, directions will be provided for the activity.

Station Five: Kidney Dissection
- Upon receiving your kidney, identify the renal hilum, from which the renal artery, renal vein, and ureter protrude (it is also the indented portion of the kidney).
- Now lay the kidney on its broadest most flat portion, with the renal hilum facing opposite your dominant hand (if you are right-handed, the hilum should be facing left).
- Using the scalpel from your dissection kit, cut the kidney in half lengthwise from the side, meaning, your scalpel should begin at the anterior, medial section of the kidney and work its way down to the posterior medial section. (DO NOT make sawing motions with the scalpel.) Continue making these incisions with your scalpel until you have separated the halves of a kidney
- Obtain pins from the table and place them on as many structures as you can identify. Your lab TA will come around and ask you to identify the pins you have placed.
- Before leaving the station, remove all the pins you have placed.
*If you are the last table to use this station, be sure to clean off the dissection kits in the lab’s sink.
Station Six: Filtrate Path and Blood Flow through Kidney
As a group, determine the route of urine through the various ducts of the kidney, originating at the glomerulus and ending with the urethra. Be sure to identify where along that path each of the structures on the vocabulary list is located.
As a group, determine the course of blood through the vessels of the kidney.
Note: The following three pages are left blank for the purpose of drawing out these two pathways.
