Oxygen is a byproduct generated during photosynthesis, and exits through stomata, root cell walls, and other routes. Plants can get rid of excess water by transpiration and guttation. It has been shown that the leaf acts as an 'excretophore' and, in addition to being a primary organ of photosynthesis, is also used as a method of excreting toxic ...

It can be due to infections or other conditions, including coeliac disease , and inflammatory bowel disease affects the layers of the gastrointestinal tract in different ways.
The benefits to society of managing human excreta are considerable, for public health as well as for the environment. As a rough estimate: For every US$1 spent on sanitation, the return to society is US$5.50. [23]: 2 For developing countries, the economic costs of inadequate sanitation is a huge concern.
Fecal sludge is defined very broadly as what accumulates in onsite sanitation technologies and specifically is not transported through a sewer.It is composed of human excreta, but also anything else that may go into an onsite containment technology, such as flushwater, cleansing materials and menstrual hygiene products, grey water (i.e. bathing or kitchen water, including fats, oils and grease ...
