What makes an organism look the way it looks? It's the genes! A gene is a sequence of molecules on a larger structure called the DNA. There are only 4 different molecules available and their order defines the way an organism looks like. Humans have around 30.000 genes (+/-).There are different types of genes. The most important ones in the context of the look of an organism are genes that code for proteins (the bricks of life). A sequence of 3 molecules on the DNA codes for the synthesis of one amino acid. Several amino acids are put together to form a protein (i.e. a chain of amino acids) and finally such a synthesised protein can be used for various organic building purposes.
How is a protein synthesized on the basis of a genetic code? Through a process called gene expression! The DNA containing all genes sits in the nucleus of a body cell. A molecule (mRNA) makes a copy of an exposed gene and leaves the nucleus with it making a stop at a cell organelle called the ER (Endoplasmatic Reticulum). There, other molecules called ribosomes read the copy and translate the copied code into a protein.

What is the function of the heart? It delivers chemical substances to various body parts by pumping blood that contains those substances! more to follow!
What is the function of the lunge? It provides energy by extracting oxygen out of breathed in air! more to follow!
What is the function of the brain? It produces adapted behavior by processing affective and cognitive aspects of information ! more to follow!
What does affective and cognitive processing mean? Affective processing means answering "how" questions related to stimuli, whereas cognitive processing answers "what" questions! more to follow!
Eye-opening knowledge! Don't be scared, just open your eyes and start understanding nature, especially the brain. This is the perhaps most interesting knowledge one can have!

The human mind sits in the brain and the brain contains all the neurons that process information underlying decision making and behavior production.
