Reabsorption vs. Resorption: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 19, 2023
Reabsorption is the process of absorbing substances again, often in kidneys; resorption is the breakdown and assimilation of tissues, like bone.

Key Differences

Reabsorption primarily occurs in the kidneys, where essential substances like water, glucose, and salts are reabsorbed into the bloodstream. In contrast, resorption refers to the process where body tissues, especially bone, are broken down and the minerals are assimilated back into the body. Reabsorption is a selective process, crucial for maintaining homeostasis in the body, whereas resorption is a part of natural physiological processes like bone remodeling.

In reabsorption, specific mechanisms in the kidney tubules actively transport certain substances from the filtrate back into the blood. On the other hand, resorption involves the breakdown of solid tissue, often bone, by cells such as osteoclasts. Reabsorption helps in conserving valuable nutrients and maintaining the body's internal environment, while resorption plays a key role in growth, healing, and maintaining the mineral balance in the body.

The process of reabsorption is critical in regulating the body's water and electrolyte balance, directly impacting kidney function and overall fluid balance. Resorption, particularly of bone, is essential in shaping and repairing bones and is influenced by various hormones and nutritional factors. Reabsorption can be influenced by various factors like hydration levels and hormones, whereas resorption is often affected by age, hormonal changes, and certain diseases.

In the context of diseases, impaired reabsorption in the kidneys can lead to conditions like diabetes insipidus, whereas abnormal resorption can result in osteoporosis. Reabsorption is often targeted by diuretics to treat conditions like hypertension, while treatments for osteoporosis aim to regulate bone resorption.

Both reabsorption and resorption involve the process of absorption, reabsorption is specific to the kidney and vital for fluid and electrolyte balance, and resorption is mainly associated with the breakdown of tissues, particularly bone, playing a crucial role in growth and maintenance.
