Animal Quote by August Krogh
“When a suitable quantity of India ink is introduced into the circulation of a living anaesthetized animal, it is evenly mixed with the blood, and if the animal is suddenly killed by stopping the circulation a few minutes later, and preparations are made from the muscles and other organs, these show the capillaries which were open at the time.”
About This Quote
Source Scientific Paper: Study of Microcirculation, 1925
Injecting ink into blood reveals which capillaries were open at the moment of death, mapping circulation pathways.
In simple terms: Ink shows open capillaries at death.
