Ischaemic (“is-skeem-ic”) stroke occurs when an artery to
the brain is blocked.
The brain depends on its arteries to bring fresh blood from the
heart and lungs. The blood carries oxygen and nutrients to the brain, and takes away
carbon dioxide and cellular waste. If an artery is blocked, the brain cells (neurons)
cannot make enough energy and will eventually stop working.
If the artery remains
blocked for more than a few minutes, the brain cells may die.
Le Corbusier conceived the master plan of
Chandigarh as analogous to
human body,
with a clearly defined head (the Capitol Complex, Sector 1),
heart (the City Centre Sector-17),
lungs (the leisure valley, innumerable open spaces and sector
greens),
the intellect (the cultural and educational institutions),
the circulatory
system (the network of roads, the 7Vs)
and the viscera (the Industrial Area).
