You are misusing the word "Intelligent" as in ID to mean "very smart" when what it means is that the presence of Design at all implies that An Intelligence, that is, a Mind, designed it. I'm sure you know that, you just like to make yourself smarter than God. Of course God is smarter than you but we'll just pass on by that.
You find God fails your personal test for IQ in the design of the eye and the blood. I'm sure He's very interested in your opinion and will let you know what He thinks of it in due time.
Leaving that aside, some of your complaints concern parts of the body that can be explained in terms of the Fall, not the original design of the Creation. The appendix for instance is very likely an organ that used to have a function, that it lost over the millennia due to the gradual deterioration of the body since the Fall. Wisdom teeth are no doubt a similar situation. Perhaps hemoglobin also used to serve functions now lost.
The Fall is all about human sin, human failure. You might think of that when you put yourself above the God who made you.
I'm sure you COULD go on for days telling God what He got wrong, such is the arrogance of the human race.
