1. A body insertable system comprising:

  • a body insertable apparatus that is introduced inside a subject, acquires intra-subject information as information concerning the subject, and transmits radio signals including the acquired intra-subject information; and

    a receiving apparatus that performs reception processing of the radio signals transmitted by the body insertable apparatus, whereinthe body insertable apparatus includes;

    an intra-subject information acquiring unit that acquires the intra-subject information;

    a magnetic field sensor that detects a magnetic field in a region where the body insertable apparatus is located; and

    a radio transmitting unit that transmits radio signals including at least the intra-subject information, andthe receiving apparatus includes;

    a receiving unit that includes at least a receiving antenna which receives the radio signals transmitted by the body insertable apparatus and a receiving circuit which performs reception processing on the radio signals received by the receiving antenna; and

    a position detecting unit that includes a magnetic field generator which generates a predetermined magnetic field for position detection in a region where the body insertable apparatus can be present, and a position calculator that calculates a position of the body insertable apparatus based on a result of detection of the magnetic field for position detection acquired by the magnetic field sensor, the position detecting unit being formed separately and independently of the receiving unit.
