Travel agents or agencies must have an identifying number called an IATA, or International Air Transport Association, number to work with travel suppliers such as tour operators and airlines. Having IATA accreditation simplifies the business relationship between travel suppliers and travel agents.
Shunt (medical) In medicine, a shunt is a hole or a small passage which moves, or allows movement of, fluid from one part of the body to another. The term may describe either congenital or acquired shunts; and acquired shunts (sometimes referred to as iatrogenic shunts) may be either biological or mechanical.
A shunt valve is part of a ventriculoperitoneal (VP) shunt used in treating diseases such as hydrocephalus. Hydrocephalus is a condition involving an abnormal accumulation of cerebrospinal fluid (CSF), the clear fluid which circulates around the brain and spinal cord, inside the skull.
