Dear Daughter,
This is my first letter to u da, the point that I would like to stress to u now in this letter is the fact that was quiet strange from the conventional point of view.
Brain is my most favourite arena, my dream field - but u my daughter have a fascination for the Heart.
Rather than looking for the differences in our passion , let me say to u someting very interesting da.
Brain and Heart have some similarities, Yes - The cardiocytes and the Neurons share some characters in common - Take your Physiology Textbook and see the topic ANP ( Atrial Natriuretic Peptide) , this hormone is from the Heart - Yes da the heart can sense the increased pressure in its chamber and when the pressure is more it can secrete a hormone , the ANP which can swim in the sea of blood to reach the brain and can then activate the necessary changes needed for the incresed excretion of urine by the kidneys , such that the blood volume will then comedown and the pressure will stand alleviated.
Very nice to learn da.
The Religious scriptures also speak about the similarity and relation between the Brain and the Heart (refer Holy Quran)
