It depends on your definition of "survive".
Some fish eggs are able to survive passage through a bird's digestive system due to their hard outer coating, which enables them to be dispersed to new environments. This process is known as endozoochory. However, not all fish eggs can survive this journey due to variations in the thickness of their outer coats and the conditions within the bird's digestive system.
The digestive system has smooth muscle through out it, and they help move the food.
Muscle motion in your digestive system called Peristalsis helps the food to travel through your digestive system.

Digestive

Amoeba engulf.
MUSCULAR
through osmosis
Because the excess matter, after passing through the digestive system, must be somehow gotten rid of and so it flows through the excretory system and is then "deposited"
by peristalsis
The muscular system is needed in the digestive system because the food (or other objects entered through the mouth) needs to be pushed through the system somehow.
