The trachea is your windpipe, so food shouldn't go down there. However peristalsis does help push food down the Oesophagus into the stomach.
It depends on how hard you push. The trachea is protected with up to a dozen strong C-shaped rings made out of rigid and strong hyaline cartilage so that it stays open for air to pass through. It would be difficult to close it off without breaking the cartilage, but a severe enough blow could do it, and then you'd need emergency medical treatment.

As a reaction it will push up trying to float
The esophagus of a fetal pig, like many organs and body parts, looks very similar to that of a human. It is a long narrow tube, pinkish in color, with cilia lined in the inside (to help push down the food). Click on the link below for pictures of a fetal pig esophagus:
