These exhibits are presented as an opportunity to learn about human anatomy and health, but they have also generated controversy and criticism for the way the bodies are obtained, the respect for the deceased and the ethics behind their display.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tissue preservation techniques used in human anatomy<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are several tissue preservation techniques used in anatomy for the preparation of specimens for study, teaching and long-term preservation. In the case of preserving blood vessels, some of these techniques are:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Plastination<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Plastination is a tissue preservation technique developed in the 1970s by the German anatomist Gunther von Hagens. In plastination, a process of dehydration and fluid replacement is used to replace tissue fluids and lipids with plastics or synthetic resins, creating a permanent sample of human or animal tissue.<\/p>\n\n\n\n<figure class=\"wp-block-image alignfull size-large\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/avcXl3n.jpeg\" alt=\"-\" title=\"\"><figcaption class=\"wp-element-caption\"><em>&#8220;The Thinker&#8221; features dissections highlighting the blood vessels of the brain and body.<\/em><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/ZZ5jZix.png\" alt=\"-\" title=\"\"><figcaption class=\"wp-element-caption\"><em><a href=\"https:\/\/www.menzelphoto.com\/image\/I0000sAomGviDFLM\" target=\"_blank\" rel=\"noopener\">Adult blood vessels<\/a><\/em><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/W4ZtrM7.png\" alt=\"-\" title=\"\"><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/www.vonhagens-plastination.com\/pages\/medical-teaching-specimens\/von-hagens-plastination.php\/blood-vessel-configurations\" target=\"_blank\" rel=\"noopener\"><em>Heart Blood Vessels<\/em><\/a><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/FwADdlf.png\" alt=\"-\" title=\"\"><figcaption class=\"wp-element-caption\"><em>Blood vessels of the leg<br><\/em><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/QrTBHYn.png\" alt=\"-\" title=\"\"><figcaption class=\"wp-element-caption\"><em>Blood vessels of the hand<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Corrosion molding<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.cambridge.org\/core\/journals\/microscopy-and-microanalysis\/article\/abs\/vascular-corrosion-casting-review-of-advantages-and-limitations-in-the-application-of-some-simple-quantitative-methods\/E00FFEDED7B5AD9F1E0B63561C98B49E\" target=\"_blank\" rel=\"noopener\">Corrosion molding<\/a> is a technique used in anatomy to create a three-dimensional replica of blood vessels and other duct systems in the human or animal body.<\/p>\n\n\n\n<figure class=\"wp-block-image alignleft size-large\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/w8FS8LE.jpg\" alt=\"-\" title=\"\"><figcaption class=\"wp-element-caption\"><em><a href=\"https:\/\/www.ripleys.com\/weird-news\/corrosion-cast-heart\/\" target=\"_blank\" rel=\"noopener\">Sheep heart<\/a><\/em><br><br><br><br><br><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In this technique, a liquid plastic or metallic material is injected into the duct system and, once the material solidifies, the tissue is immersed in a chemical solution that dissolves the soft tissue and exposes the three-dimensional cast of the duct system.
