A vessel receives and agitates a fluid using an internal fluid-agitating element driven by an external motive device. In one aspect, the vessel is a bag including a first receiver for receiving and holding a fluid-agitating element at a home location. The first receiver may be in the form of an inwardly-projecting post having an oversized portion for capturing the fluid-agitating element, but various other forms are disclosed. Use of this feature in completely rigid vessels where the fluid-agitating element is free of direct attachment from a first receiver having an oversized portion is also disclosed. In another aspect, the vessel or bag further includes a second receiver for receiving a portion of an external structure, such as a motive device, and aligning the vessel relative thereto.
