We have clocks everywhere" //many different internal clocks throughout the body change in height has a lot of limitations as a biomarker [has to be measured at the same time every day] bones aren"t just solid. Made of blood plasma, calcium, phosphate a functional calcium store homeostasis systems will take the calcium from the bones to keep the blood- calcium level stable.
