2. The tip section of claim 1, wherein said one or more support elements comprise one or more camera holders configured to support the front camera, the side camera, and/or an optical assembly thereof.

3. The tip section of claim 1, wherein the at least one light source comprises a plurality of side light sources positioned proximate the side camera and in the planar portions of the pair of opposite sides, wherein the fluid channeling component further comprises, on each of the pair of opposite sides, one or more openings for receiving one or more of said plurality of side light sources.

4. The tip section of claim 3, wherein the fluid channeling component further comprises, on each of said pair of opposite sides, an opening to receive the side camera, located between two openings for receiving one or more side light sources, and wherein the opening to receive the side camera and the two openings for receiving said one or more side light sources are entirely on planar portions of the pair of opposite sides.

5. The tip section of claim 3, wherein the fluid channeling component further comprises one or more side openings of said one or more fluid channels, for emitting fluid toward at least one of the side camera and one or more of the plurality of side light sources to clean the at least one of the side camera and one or more of the plurality of side light sources.

6. The tip section of claim 1, wherein the at least one light source includes at least one front light source, wherein the fluid channeling component further comprises a front opening of said one or more fluid channels, for cleaning said front camera, said optical assembly thereof, and/or the at least one front light source, and wherein the front opening is on a planar distalmost surface of the tip section.

7. The tip section of claim 1, wherein the fluid channeling component further comprises a working channel adapted for the insertion of a medical tool.

8. The tip section of claim 1, wherein the fluid channeling component further comprises a groove configured to accommodate a jet fluid tube for cleaning a body cavity into which said multi-camera endoscope is inserted.

9. The tip section of claim 1, wherein the fluid channeling component further comprises a jet fluid channel for transferring therethrough fluid for cleaning a body cavity into which said multi-camera endoscope is inserted.

10.
