Pig tissues exhibit several unique histological features that are studied extensively:
Epidermis: Similar to human skin, pig epidermis consists of multiple layers, including the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.
Cardiac Muscle: Pig cardiac muscle tissue shows striations and intercalated discs, which are crucial for synchronized contractions. The myocardial structure is comparable to that in humans.
Renal Tissue: Pig kidneys have a well-defined cortex and medulla, with clear distinctions between the nephron segments, glomeruli, and tubules.
Hepatic Tissue: The liver tissue in pigs exhibits a lobular architecture with hepatocytes arranged in cords around central veins, resembling human liver histology.
Respiratory Epithelium: The respiratory tract of pigs has a pseudostratified ciliated columnar epithelium, similar to that in humans, facilitating studies on respiratory diseases.
