Comparing an ostrich digestive system with a human digestive system By KATELYN

The ostrich digestive system has many parts. First the food, like lizards and rodents, is collected in the crop which is a muscular pouch near the throats and all the food is stored on top of the throat till there is a big enough lump of food to slide down the long neck into the stomach. Then the food travels into the gizzard where the food is crushed and broken down into little pieces. The food passes into a very long intestine then the food travels down towards cloacal where urine and smash food are excreted
Human Digestive System: The mouth is the starting of the digestive system. It's job is to break down the food so it can be swallowed. Your teeth bite down the food till it's nice and soft and mushy. Your tongue moves your food around with the saliva to make it easier to swallow. All your food moves into the oesophagus. The Esophagus is a long tube that runs from your mouth to your stomach. The esophagus use the muscles to squeeze the food down to your stomach. The stomach is a pear-shaped organ at the end of the oesophagus gets bigger when it's filled with food. Do you know juices in the stomach breaks down the food even more. The stomach also mixes the food. By the time the food mixture leaves your stomach it's a thin watery liquid. Then the liquid mixture goes to your small intestine. The small intestine is a long tube that swings back-and-chemical juices into a small intestine to help break down the food even more. Where do chemical juices come from some? They come from the pancreas and some come from the liver. The Liver is an organ that helps break down fats in your food. Any waste leftovers go to your large intestine. The large intestine is another tube. It is much wider and shorter than the small intestine. The first part of the large intestine is called the colon. The colon squeezes most of the water of the wastes that is put back into your body. The solid waste that are left exit lower port of the long intestine called the rectum.
did you know on this list the ostrich has the second biggest body length at 80 cm the emu is the first biggest body length 130 cm
The one major difference of the digestive system of a human ostrich is the crop. The crop in the ostrich is used for sorting food until there is sufficient amount of food to be swallowed and passed into the stomach. Where as in humans whenever we chew and swallow, the food passes straight through the esophagus and into the stomach. So no matter how much we swallow no food will be stopped
You probably don't know what this is. Well this is a lot of gizzards from birds. Do humans have a gizzard? No we do not have a gizzard. Birds have a gizzard because they don't have teeth. The gizzard is like their teeth because the food gets grind into little pieces. The gizzard is part of their stomach. In the gizzard there is sand and small stones and it's the second port of the stomach.
It can take up to 36 hours from the time an Ostrich eats to when it has been fully digested. They have three stomachs that the food goes through before it enters the intestines and can be used for nutrition and energy. An ostrich eats an average of 8 pounds of food per day compared to an adult who eats an average of 5.4 pounds per day.
An ostrich is born weighing an average of 3 pounds compared to a human baby who weighs an average of 7.5 pounds. A full grown ostrich can weigh anywhere from 220 to 350 pounds , where humans average 130-190 pounds. That shows that even though they start out smaller than humans they quickly grow to much bigger. By the age of one year old they typically weigh around 100 pounds.
