Question 49

Absorption of calcium and phosphate from the digestive system provide minerals for bone formation. Hormones, like estrogen, from the reproductive system influence growth of long bones in the appendicular system.

The tuberosities on long bones provide attachment sites for tendons in the muscular system. White blood cells, which are formed in marrow of long bones, contribute to the lymbic systems function.
