Systolic pressure is the amount of pressure in the arteries when contraction takes place in heart. Diastolic pressure is the pressure the heart when it relaxes. It is the lower number of blood pressure reading
When the systolic pressure is >120mm Hg and diastolic is less than 80mm Hg it is normal
120-129mm Hg and diastolic less than 80mm Hg it high and such person needs a regular medical check up
But when systolic 129-139 mmHg
and diastolic is 90mm Hg or above it means the individual is having hypertension stage 1
Above 140mm Hg is hypertension stage 2 and it is the most severe stage. It means the person is hypertensive and medical attention needs to be seek for necessary treatment as this could lead to death of such individual if not well managed.

So, fungi is re-evaluating its position in the tree of life and in present there is a individual kingdom for fungi.
They are called reactants
