Abstract
An intra-subject observation system includes a first liquid inserted into a desired organ of a subject; and a second liquid inserted into the organ without being mixed with the first liquid due to a specific gravity lighter than that of the first liquid. The system also includes a capsule medical apparatus inserted into the organ with an intermediate specific gravity between the specific gravity of the first liquid and that of the second liquid to acquire intra-subject information, which is output out of the subject by radio.
