A composting toilet consists of two elements: a place to sit or squat and a collection/composting unit. [3] The composting unit consists of four main parts: [2] storage or composting chamber; a ventilation unit to ensure that the degradation process in the toilet is predominantly aerobic and to vent odorous gases
A flush toilet (also known as a flushing toilet, water closet (WC); see also toilet names) is a toilet that disposes of human waste (i.e., urine and feces) by collecting it in a bowl and then using the force of water to channel it ("flush" it) through a drainpipe to another location for treatment, either nearby or at a communal facility.
The modern toilet utilises a cistern to reserve and hold the correct amount of water required to flush the toilet bowl.

Gap junctions were first described as close appositions as other tight junctions, but following electron microscopy studies in 1967, they were renamed gap junctions to distinguish them from tight junctions. [2] They bridge a 2-4 nm gap between cell membranes. [3] Gap junctions use protein complexes known as connexons to connect one cell to another.
