Nephrology impact on quality and length of life, and so psychological support, health education and advanced care planning play key roles in nephrology. Chronic kidney disease is typically managed with treatment of causative conditions (such as diabetes), avoidance of substances toxic to the kidneys (nephrotoxins like radiologic contrast and non-steroidal anti-inflammatory drugs), antihypertensives, diet and weight modification and planning for end-stage kidney failure. Impaired kidney function has systemic effects on the body. An erythropoetin stimulating agent may be required to ensure adequate production of red blood cells, activated vitamin D supplements and phosphate binders may be required to counteract the effects
Sensory organs of gastropods Sensory organs of gastropods The sensory organs of gastropods (snails and slugs) include olfactory organs, eyes, statocysts and mechanoreceptors. Gastropods have no sense of hearing. In terrestrial gastropods the most important sensory organs are the olfactory organs which are located on the tips of the 4 tentacles. In opisthobranch marine gastropods, the chemosensory organs are two protruding structures on top of the head. These are known as rhinophores. An opisthobranch sea slug "Navanax inermis" has chemoreceptors on the sides of its mouth to track mucopolysaccharides in the slime trails of prey, and of potential mates. The freshwater snail "Bithynia tentaculata"
