As I read it, these physicists came across the notion of windkessel in some medical/physiological literature and realized that this is an understudied physical phenomenon. So I think the claim is less that they’re doing something revolutionary for understanding the circulatory system but rather that they’ve come across something whose underlying physics are a lot less studied than they expected.
