Because Christianity doesn't require the belief that God gave us perfect bodies, I don't need to. That said:
1. A couple of these are a little silly. I'm not a doctor, but for example I'd imagine that a ball and socket joint at the knee would be worse than the knee we actually have (more prone to failure, needlessly complex, etc.). The one about the pharynx also just admits that their "solution" would interfere with our ability to speak.
2. Some of these (like the one about our eyes) are likely more complicated than even experts realize. In the same way that we used to think our appendix was vestigial and now no longer do, I imagine future research will reveal that there's a good reason for some of these "flaws."
3. Is it a flaw of design that I can't drop a cinder block on my phone if I want it to keep working? The fact is that when you're working with physical materials, you are necessarily limited and have to choose what problems you want to solve and what problems you're willing to put up with. Some of these "issues" never impact us in our day-to-day lives, and are thus totally acceptable.
4. It's entirely feasible that God created us in a flawed state knowing that the butterfly effect of our flaws would bring about more good than harm. Perhaps our bad backs are the only reason chiropractors exist, and therefore are the only reason why some of us practice medicine and thereby are made more caring and humble. Perhaps our bodies break down with age intentionally, so that the young are made to care for their parents, which has caused us to value and respect our elders more than we otherwise would. Or maybe we have a blind spot so that a person who would otherwise start World War 3 will instead get accidentally hit by a truck. We have literally no way of knowing whether things would be better if these things changed.
5. If (not that he necessarily did, so please don't start an argument, YECs) God decided to create humans via evolution, perhaps this is as good as He could have made us, all things considered.
6. Perhaps our limitations are the just desserts for our sin, and will be taken away in Heaven. Consider that in Genesis God tells Eve that painful childbirth is a result of the Fall, for example.
7. Perhaps our flaws are there to provide plausible deniability to the notion that we were designed. God wants us to freely choose Him, and perhaps some level of doubt about His existence is necessary to keep some from being forced into belief.
