I don’t know how to handle this Health & Medical question and need guidance.
It is true that the brain has three crucial functions, the cognitive, the neurological, and the perceptual functions. I also think the brain is the most complex organs in the body, as unlike other organs such as the heart or lungs which have one primary role, the brain is made to perform numerous roles for the body (The Internet Stroke Center. n.d., 2020). Damaging the brain or any part of the body that helps in nourishing the brain can have numerous consequences, most of which are fatal. The development of stroke, for instance, happens from a very simple process in the body- the formation of a clot in a blood vessel leading to the brain.
