The organ most vulnerable to ischaemia due to shock-
The susceptibility of a tissue to hypoxia influences the likelihood of infarction.
Neurons are most sensitive to hypoxia (irreversible changes develop in 3-4 minutes) followed by myocardial cells (irreversible changes develop in 20-40 minutes).
Fibroblasts are amongst the most resistant cells to hypoxia.
