No, just a fast digestive system.
Cedar berries are eaten by birds, and pass through their digestive system. When the birds poop, the seeds grow where they land.
it all depends on the animal, cow for example, have 4 organs that are like a stomache. birds, have a very different digestive system.
A gizzard is a muscular organ inside a bird that grinds up food.
Gizzards come from the digestive system of birds, where they help grind up food for digestion.
It is part of the digestive system of a bird - it is the first major structure after the oesophagus. It is where seed is stored before being gradually fed into the rest of the digestive system.
The function of the crop in the digestive system of the the bird is to temporarily store food for later digestion. In seed eating birds the crop is like a pouch in the esophagus and no real digestion occurs there it occurs in the gizzard which grinds it all up.
a organ systems are shared by both fish and birds because they have the same respiratory system, nervous system and reproductive system.
Yes, the human digestive system works through muscular contractions which force the food and liquid along. This is why we have no problems in space (apart from getting the food to stay on the plate). You can demonstrate this by hanging upside down and eating a sandwich just fine. Interestingly, the digestive system of many birds does depend on gravity; this was discovered during a Space Shuttle mission to see if birds could handle space.
