In science, ex vivo refers to experimentation or measurements done in or on tissue from an organism in an external environment with minimal alteration of natural conditions. [ 2 ] A primary advantage of using ex vivo tissues is the ability to perform tests or measurements that would otherwise not be possible or ethical in living subjects.
Hypothermic perfusion of kidneys is a relatively widespread practice. For the heart normothermic preservation has been used in which the heart is provided with warm oxygenated blood and so continues to beat ex-vivo during its preservation.
Ex vivo reconstruction, short for ex vivo renal artery reconstruction and autotransplantation, is a technique mainly used for complex disease involving multiple segmental branches in patients with fibromuscular dysplasia.
Ex vivo lung perfusion, EVLP, is a form of machine perfusion aimed at sustaining the active aerobic cellular metabolism of donor lungs outside the donor's body prior to lung transplantation. This medical preservation technique typically occurs within a specialised machine engineered to mimic the conditions of the natural circulatory system .
The Langendorff heart or isolated perfused heart assay is an ex vivo technique used in pharmacological and physiological research using animals and also humans. [1] Named after the German physiologist Oskar Langendorff , this technique allows the examination of cardiac contractile strength and heart rate without the complications of an intact ...

The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [ 1 ]
A prosection is the dissection of a cadaver (human or animal) or part of a cadaver by an experienced anatomist in order to demonstrate for students anatomic structure. [1] In a dissection, students learn by doing; in a prosection, students learn by either observing a dissection being performed by an experienced anatomist or examining a specimen that has already been dissected by an experienced ...
