* Aortic valve: The aortic valve is located between the left ventricle and the aorta. It is typically around 2.5 to 3.5 centimeters (cm) in diameter.
* Mitral valve: The mitral valve is located between the left atrium and the left ventricle. It is usually about 3 to 4 cm in diameter.
* Pulmonary valve: The pulmonary valve is situated between the right ventricle and the pulmonary artery. It is approximately 2 to 2.5 cm in diameter.
* Tricuspid valve: The tricuspid valve is placed between the right atrium and the right ventricle. It is typically around 3.5 to 4.5 cm in diameter.
It's important to note that these are just approximate measurements, and the actual size of a pig heart valve may vary from these values.
