Plain Sheep Kidney Dissection Specimen for Biology Labs | Mammalian Anatomy

This plain preserved sheep kidney dissection specimen is a high-quality educational specimen commonly used in middle school, high school, and introductory college biology labs to teach mammalian anatomy and excretory system function. Sheep kidneys are an excellent model for anatomy studies because their size and internal structure closely resemble those of the human kidney. Each specimen is preserved to maintain clear visibility of anatomical structures, making it ideal for hands-on classroom dissection. Students begin by examining the external anatomy of a sheep kidney, then proceed to explore the internal anatomy of the kidney to better understand filtration, waste removal, and fluid balance.

Sheep Kidney Anatomy Structures (External & Internal):

Renal capsule
Renal cortex
Renal medulla
Renal pyramids
Renal columns
Renal pelvis
Calyces
Ureter
Renal artery
Renal vein
Nephrons
Collecting ducts

This preserved sheep kidney specimen for dissection supports instruction in vertebrate biology, physiology, and human anatomy comparison, making it an excellent choice for anatomy labs, life science courses, and homeschool science programs. Pair it with a sheep kidney dissection kit that includes tools, a dissecting guide, and a tray for a complete lab experience. Specimens are initially fixed using a formaldehyde solution to preserve tissue structure, then rinsed and stored in a glycol-based solution, producing a moist, low-odor, long-lasting specimen suitable for educational use.

Did You Know? Each sheep kidney contains millions of tiny filtering units called nephrons. In humans, if all the nephrons from one kidney were laid end to end, they would stretch for more than 50 miles—showing just how efficient and complex the excretory system really is.

Store specimens in an area of room temperature away from direct sunlight. Do not freeze or expose to high temperatures (more than 85ºF). Specimens will last up to 12 months when left unopened. After opening, the specimen should be placed in a zip-top bag and may be kept for up to one month.

Discounts available for purchases of 10 or more sheep kidney specimens!
