Answer 1

Answer:

no we cannot leave without brain,Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.

no we can't leave without heart,A device called the Total Artificial Heart helps some of the sickest heart-failure patients regain function — outside of the hospital — while awaiting a transplant.

Answer 2

Answer:

1. yes we can live without brain

Reason:

To understand this, let us look at a case. In 2014, a 24 years old Chinese woman complained in a hospital about her nausea and dizziness. After a CT scan, the doctors found that the woman was born without a cerebellum but yet lived her life normally without knowing anything about it.

This is because the brain’s functionality is not just localized to these parts, but rather spread across the brain. The interesting fact is that most of these brain parts have the power to adapt to the functionality of other parts. This phenomenon is popularly called as Neuroplasticity.

Another interesting case occurred in 2001 when Trevor Waltrip was born without a forebrain. This condition is called as Hydranencephaly where the usual cerebral hemispheres are missing and the cranial cavity is filled with just cerebrospinal fluid. But even without a brain, Trevor Waltrip lived for 12 years. Thus he set an example of the limits of human survival without a brain.

But how did Trevor Waltrip managed to live without a brain? Even though he did not have his cerebral hemispheres, he still had his brain stem intact. This allowed him to breathe, maintain his heartbeat and respond to some basic stimuli. So we can see that the brain stem is the most important part of the brain which is necessary for human survival.
