Infarction
Which types of organs are relatively resistant to infarction?
Those with a dual blood supply eg, liver and lungs
What is the result of collateral circulations?
They allow for alternate blood route in the instance of an occlusion
Which cells are very vulnerable tom infarction and will die after 3-4mins?
Neurones

Atheroma
Anaemia
Vascular spasm (constant contraction of the arteries due to vasoconstrictors= ↓ blood flow)

Which organ is affected in a transient ischaemic attack (TIA)
The brain
Which type of arterial disease can cause blindness in one eye, can possibly cause neurological deficits, but recovers in 24 hours?
Transient ischaemic attack TIA
