Resorption vs. Reabsorption

Resorption involves the transfer of substances from a site directly into the bloodstream, excluding the intestine.
Reabsorption refers to the transfer of substances from the bloodstream back into the bone.

Key Cell Types

Osteoclasts are specialized cells responsible for breaking down bone tissue through the process known as resorption, regulated by parathyroid hormone.
Osteoblasts are cells that aid in bone formation, contributing to reabsorption, and are influenced by hormones such as calcitonin.
