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.
This trend continued in 1999â2000, with an increase in obesity of 28 percent of men and 34 percent of women. â  The percent of adults with healthy weights declined approximately 10 percent from 1960 to 1994, with an additional decline of approximately 8 percent from 1994 to 2000 (figure 2).easurements of height and weight help to assess the overall health and nutritional status of adults. Overweight, obesity, and healthy weight can be defined by the Body Mass Index (BMI), calculated as weightin kilograms/height in meters squared.
