If you are a student or a teacher of biology, anatomy, physiology, or zoology, you know how important it is to have a hands-on experience with the organs of the body. Dissecting a real specimen can help you understand the structure, function, and evolution of the organ, as well as compare it with other animals and humans.
One of the most fascinating and vital organs to dissect is the heart. The heart is responsible for pumping blood throughout the body, delivering oxygen and nutrients to the cells, and removing waste products. The heart also plays a key role in the circulatory system, which connects with other systems such as the respiratory, digestive, and immune systems.
But where can you find a suitable heart specimen for dissection? You can’t just use any animal’s heart, because not all hearts are alike. Some animals have different numbers of chambers, valves, and vessels in their hearts, which can make them difficult to compare with human anatomy. You also want to avoid using endangered or protected species, or animals that are too large or too small for your purposes.
That’s why a sheep heart specimen is a perfect choice for dissection. A sheep heart is similar in size and shape to a human heart, and has the same four-chambered structure and major vessels. A sheep heart is also easy to obtain, affordable, and safe to handle. A sheep heart can help you learn about the anatomy of the heart in a realistic and engaging way.
What to Look for in a Sheep Heart Specimen
Not all sheep heart specimens are created equal. Some specimens may be better preserved, injected, or packaged than others, which can affect their quality and usability. Here are some factors to consider when choosing a sheep heart specimen for dissection:
– Preservation: The preservation process is crucial for keeping the specimen intact and preventing decay, fungal growth, or desiccation. The most common and effective preservative is formalin, which is a solution of formaldehyde and water. Formalin can fix the tissue and prevent decomposition, but it can also have a strong odor and pose health risks if inhaled or ingested. Therefore, it is important to choose a specimen that has been washed and stored in a non-toxic, non-formaldehyde holding solution, which can reduce the formalin odor and make the specimen safer to handle.
– Injection: Some specimens may be injected with colored latex to highlight the different systems of the heart, such as the arterial, venous, and hepatic systems. This can make it easier to identify and trace the vessels and valves of the heart, and to compare them with other specimens. However, some students or teachers may prefer a plain-injected specimen, which has not been injected with colored latex, and shows the natural colors of the systems. A plain-injected specimen can be more challenging and realistic, and can help students develop their observational and analytical skills.
– Packaging: The packaging of the specimen can affect its shelf life and storage. The best way to package a specimen is to vacuum-pack it in a heavy mylar-coated poly bag, which can prevent air and moisture from entering and damaging the specimen. A vacuum-packed specimen can last for up to 12 months in its original packaging, and can be used for multiple dissections if stored properly. A vacuum-packed specimen can also be shipped and delivered more easily and safely than a specimen in a jar or a pail.
How to Compare Sheep Heart Specimens
There are many sheep heart specimens available on the market, but not all of them meet the criteria mentioned above. To help you choose the best sheep heart specimen for your needs, we have compared four popular products based on their preservation, injection, packaging, price, and customer reviews. Here is a table that summarizes the comparison:
| Product Name | Preservation | Injection | Packaging | Price | Customer Reviews |
|---|---|---|---|---|---|
| Anatomy Lab Preserved Sheep Heart Specimen for Dissection, for Biology Classrooms, Vacuum Pack of 1 | Formalin, then washed and stored in non-toxic, non-formaldehyde holding solution | Plain-injected | Vacuum-packed in heavy mylar-coated poly bag | $21.99 | 5.0 out of 5 stars, 3 ratings |
| Sheep Heart for Dissection | Preserved Sheep Heart Specimen | HST | Formalin, then rinsed and stored in low-odor holding fluid | Plain-injected | Vacuum-packed in heavy mylar-coated poly bag |
| Sheep heart specimen | Cornerstone Educational Supply | Formalin, then rinsed and stored in low-odor holding fluid | Plain-injected | Vacuum-packed in heavy mylar-coated poly bag | $9.95 |
| Ward’s® Pure Preserved™ Sheep Heart Dissection Kit | Formalin, then washed and stored in non-toxic, non-formaldehyde holding solution | Colored latex injected | Vacuum-packed in heavy mylar-coated poly bag | $14.95 | No ratings |
As you can see, the Anatomy Lab Preserved Sheep Heart Specimen for Dissection, for Biology Classrooms, Vacuum Pack of 1 is the most expensive product, but it also has the highest customer ratings and the best preservation quality. The other products are cheaper, but they have no customer ratings and may have lower preservation quality. The Ward’s® Pure Preserved™ Sheep Heart Dissection Kit is the only product that has colored latex injection, which can be an advantage or a disadvantage depending on your preference.

– Positive: “I bought this for my daughter who is studying anatomy and physiology in high school. She loved dissecting the sheep heart and learning about the different parts and functions. The specimen was well-preserved and easy to handle. It had a low formalin odor and did not irritate her skin or eyes. The specimen was also large enough for her to see the details clearly and compare them with human anatomy. She said it was a fun and educational experience.”
– Positive: “This was a great product for my biology class. The sheep heart specimen was in excellent condition and arrived on time. It was vacuum-packed and sealed in a poly bag, which made it convenient to store and use. The specimen was plain-injected, which I preferred because it showed the natural colors of the systems. The specimen was also similar in size and shape to a human heart, which made it easier to understand and relate to. The dissection was a success and the students learned a lot.”
– Negative: “I was disappointed with this product. The sheep heart specimen was poorly preserved and had a strong formalin smell. It also had a lot of excess fat and tissue that had to be trimmed before dissection. The specimen was too small and hard to dissect. It was difficult to identify and trace the vessels and valves of the heart. The dissection was a waste of time and money.”
