Your brain creates a mental image of what you look like based on sensory information and memories. This image may not always match your actual appearance, as it can be influenced by emotions and past experiences.
A chimp's brain is a bit smaller than a human.
In reality, the human heart does not look like the traditional heart depicted on Valentines Day cards. The human heart has several cavities; both ventricles and atrium's. It also contains valves (pulmonary, aortic, mitral, tricuspid), which move the blood throughout (in and out of) the heart. The human heart is about the size of a human fist and, because the heart is a muscle with lots of blood supplied to it, it appears red like meat. Hope this helps!

No. Humans evolved from a common ancestor we have with today's "great" apes (chimpanzees, orangutans, gorillas). This is proven specifically for human evolution by ERVs and the fused chromosome #2. Brain coral is just an example of Pareidolia... the phenomena of the human mind to see patterns in things that aren't really anything (like religious images in toast, faces in mountain sides, etc).
