Reabsorption vs. Resorption: Know the Difference
By Shumaila Saeed || Published on January 4, 2024
Reabsorption is the process of absorbing substances again, especially in the kidneys, while resorption refers to the breakdown and assimilation of bone or tissue.
Key Differences
Reabsorption is primarily a biological process where materials, particularly in the kidneys, are absorbed back into the bloodstream after being filtered. This is crucial in maintaining bodily homeostasis. In contrast, resorption is a physiological process involving the breakdown and assimilation of substances, commonly seen in bone remodeling, where bone tissue is broken down and nutrients are absorbed into the bloodstream.

In reabsorption, essential substances like glucose, amino acids, and water are selectively reabsorbed from the kidney tubules into the bloodstream, preventing wastage. Resorption, however, is more about the destruction and subsequent assimilation of materials, as observed in the bone where osteoclasts break down bone tissue, releasing minerals like calcium into the blood.

Reabsorption is a conserving mechanism, often seen in renal function, helping the body reclaim and retain vital substances from excretory pathways. On the other hand, resorption plays a pivotal role in growth, healing, and maintaining mineral balance, by breaking down tissues or structures when they are no longer needed or to release stored minerals.

Reabsorption is also a term used in environmental contexts, referring to the process where previously emitted substances, like greenhouse gases, are absorbed again by natural systems. In contrast, resorption, particularly in a medical context, relates to the body's way of recycling its components, such as in the absorption of an old or damaged tissue.

In summary, while reabsorption is about reclaiming and recycling, ensuring that valuable substances are not lost, resorption is about the strategic breakdown and assimilation of materials for various physiological requirements, be it for growth, repair, or maintaining homeostasis.
