A fluid-distributing structure includes a flexible body having a plurality of fluid reservoirs defined therein, and a plurality of directional fluid barriers. The fluid reservoirs are fluidly connected to one another by openings defined within the body. Each fluid barrier is associated with one of the openings defined in the body, and is configured to permit fluid flow through the opening in a downstream direction and inhibit fluid flow through the opening in an upstream direction.

1. A fluid-distributing structure comprising: a flexible body having a plurality of fluid reservoirs defined therein, the fluid reservoirs being fluidly connected to one another by openings defined within the body; anda plurality of directional fluid barriers, each fluid barrier being associated with one of the openings defined in the body and configured to permit fluid flow through the opening in a downstream direction and inhibit fluid flow through the opening in an upstream direction, each of the fluid barriers being moveable between an opened position and a closed position in response to deformation of the absorbent structure. 2. The fluid-distributing structure set forth in claim 1 wherein each fluid barrier is disposed between a pair of adjoining fluid reservoirs and is configured to permit fluid flow into a first fluid reservoir of the pair of fluid reservoirs and inhibit fluid flow into a second fluid reservoir of the pair fluid reservoirs. 3. The fluid-distributing structure set forth in claim 1 wherein the absorbent structure has an insult region, the fluid barriers configured to direct fluid away from the insult region. 4. The fluid-distributing structure set forth in claim 1 wherein the absorbent structure has an insult region, each fluid reservoir having a volume that varies with a distance between the fluid reservoir and the insult region, wherein the volume decreases as the distance between the fluid reservoir and the insult region increases. 5. The fluid-distributing structure set forth in claim 1 wherein the body comprises a material having an elastic modulus between about 50 kPa and about 350 kPa at a strain of about 20%. 6. The fluid-distributing structure set forth in claim 1 wherein the body includes an upper surface and a lower surface spaced apart from one another along a vertical direction of the absorbent structure, the body comprising a plurality of walls extending from the upper surface to the lower surface, wherein the openings are defined within the walls of the body. 7. A fluid-distributing structure comprising: a flexible body having a plurality of fluid reservoirs defined therein, the fluid reservoirs being fluidly connected to one another by openings defined within the body; anda plurality of directional fluid barriers, each fluid barrier being associated with one of the openings defined in the body and configured to permit fluid flow through the opening in a downstream direction and inhibit fluid flow through the opening in an upstream direction, wherein at least one fluid barrier comprises a valve member moveable between an opened position in which the valve member permits fluid flow in the downstream direction, and a closed position in which the valve member inhibits fluid flow in the upstream direction. 8. The fluid-distributing structure set forth in claim 7 wherein the valve member is movable from the closed position to the opened position by deformation of the body. 9. The fluid-distributing structure set forth in claim 7 wherein the valve member includes in upstream side and a downstream side, the upstream side comprising a relatively hydrophobic surface, and the downstream side comprising a relatively hydrophilic surface. 10. An absorbent article comprising: a bodyside liner;an outer cover; andan absorbent structure disposed between the liner and the outer cover, the absorbent structure comprising: a flexible body having a plurality of fluid reservoirs defined therein, the fluid reservoirs being fluidly connected to one another by openings defined within the body; anda plurality of directional fluid barriers, each fluid barrier being associated with one of the openings defined in the body and configured to permit fluid flow through the opening in a downstream direction and inhibit fluid flow through the opening in an upstream direction, wherein each of the fluid barriers is moveable between an opened position and a closed position in response to deformation of the absorbent structure. 11. The absorbent article set forth in claim 10 wherein at least one fluid barrier comprises a valve member moveable between an opened position in which the valve member permits fluid flow in the downstream direction, and a closed position in which the valve member inhibits fluid flow in the upstream direction. 12. The absorbent article set forth in claim 11 wherein the valve member is movable from the closed position to the opened position by deformation of the body. 13. The absorbent article set forth in claim 10 wherein the body comprises a material having an elastic modulus between about 50 kPa and about 350 kPa at a strain of about 20%. 14. The absorbent article set forth in claim 10 wherein the absorbent structure includes an upper surface and a lower surface, the upper surface facing the bodyside liner and the lower surface facing the outer cover, wherein the upper surface comprises a relatively hydrophobic surface and the lower surface comprises a relatively hydrophilic surface. 15. The absorbent article set forth in claim 10 wherein the absorbent article is one of a diaper, a training pant, a sanitary napkin, an adult incontinence garment, a surgical pad, or a medical bandage. 16. A fluid-distributing absorbent structure comprising: a flexible body having a plurality of voids defined therein, wherein the voids are in fluid communication with one another; anda plurality of directional fluid barriers, each fluid barrier disposed between a pair of adjoining voids and configured to permit fluid flow into a first void of the pair of voids and to restrict fluid flow into a second void of the pair voids, wherein at least one fluid barrier comprises a valve member moveable between an opened position in which the valve member permits fluid flow into the first void, and a closed position in which the valve member restricts fluid flow into the second void. 17. The absorbent structure set forth in claim 16 wherein the valve member is movable from the closed position to the opened position by deformation of the body. 18. The absorbent structure set forth in claim 16 wherein the valve member comprises a floating valve member. 19. The absorbent structure set forth in claim 16 wherein the valve member is coupled to the body of the absorbent structure by a biasing member that biases the valve member towards the closed position.
