What is the most protected part brain or heart?

The heart is more protected than the brain.

The brain is housed within the skull, which is a hard, protective barrier. However, the skull can be penetrated by sharp objects, such as bullets or knives, and the brain can be damaged by blunt force trauma. The brain is also vulnerable to damage from strokes, which occur when the blood supply to the brain is interrupted.

The heart is located within the ribcage, which is a strong, protective barrier. The ribs are also covered by muscle, which provides additional protection. The heart is also protected by the pericardium, a tough, fibrous membrane that surrounds the heart. The pericardium helps to keep the heart in place and prevents it from being damaged by nearby organs.
