The distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule. Cells lining the tubule have numerous mitochondria to produce enough energy (ATP) for active transport to take place.he distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule.

Obesity is officially classified as a disease under the World Health Organisation's International Classification of Diseases. In a report published in 2000, the WHO said: Obesity is a chronic disease, prevalent in both developed and developing countries, and affecting children as well as adults.
The classification of obesity as a disease comes as two new weight-loss drugs were approved by the Food and Drug Administration. The AMA hopes that the new classification will lead to even more new treatments for obesity, including medication.Reclassifying this is going to encourage greater investment and research.he decision came at the annual meeting of the American Medical Association (AMA). Though a committee of experts recommended against classifying obesity as a disease, the association's delegates voted to approve the change.
