Plain Sheep Heart Dissection Specimen for Biology Labs | Mammalian Heart Anatomy

This preserved sheep heart dissection specimen is a great choice for teaching students about mammalian heart anatomy and how the heart functions to move blood throughout the body. Commonly used in middle school, high school, and introductory college biology labs, the sheep heart closely resembles the human heart in size and structure, making it ideal for hands-on study of chambers, valves, and major vessels. Each specimen is prepared to maintain clear visibility of anatomical features, making it well suited for hands-on classroom dissection focused on structure and function.

This preserved sheep heart specimen for dissection supports instruction in vertebrate biology and circulatory system function, making it an excellent choice for anatomy labs, life science courses, and homeschool science programs. Dissection specimens are preserved in formalin to fix tissues, then rinsed and vacuum packed in a low-odor holding fluid to ensure safe handling and long-lasting educational use. Each order includes one individually vacuum-packed specimen.

Did You Know? A sheep’s heart can beat more than 100 times per minute, pushing blood through a network of vessels that would stretch for miles if laid end to end—helping students appreciate how efficiently the heart supports the body’s needs.

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.
