On this episode of ID the Future, physician Howard Glicksman explains the hugely complex blood flow systems required to keep us clear-headed and alive even while doing everything from gymnastics to simply getting up in the morning. There are various methods the heart and blood vessels use to keep the body properly supplied. It’s also about hormones and nervous-system signaling. Does Darwinism provide a satisfactory explanation for such an intricately coordinated system? Dr. Glicksman argues that it does not, and that a far better explanation is intelligent design.
