humans and swine (pigs) have simple stomach digestive systems
Monogastric
Simple stomached animals, such as dogs, pigs and horses (and humans) only have one chamber in their stomach. It is generally at a low pH such as pH 2-3. Animals with a compound stomach have a much more complex arrangement. They have four compartments to their stomach. These compartments are called the reticulum, the rumen, the omasum and the abomasum. The abomasum is similar to the simple stomach. THis arrangement is so the animal can ferment the food they eat. Animals with this arrangement are known as ruminants and include sheep, goats and cows.

A simple stomach like we humans do. Pigs are monogastrics, like cats, dogs, bears, raccoons and other carnivores and omnivores do.
They both have only one stomach, and primarily pertain to the differences in digestive systems between mammals, not avians, reptiles or amphibians. Ruminants have a four-chambered stomach, whereas non-ruminants have a simple stomach.
Most animals' stomachs are called a stomach
A stomach.
well orangutans can use saws and hammers properly
It is proof that the conclusion that "all animals that are cloven hooved (or have 'two toes') are ruminants" is false. Swine are not ruminants because they have a simple stomach, not a four-chambered stomach, and thus are omnivorous animals. Other animals that are two-toed or cloven-hooved but are not ruminants are camelids (camels, alpacas, and llamas, for example), which are known as pseudoruminants due to the fact that they only have a three-chambered stomach.
Yes any animals' stomach is an organ.
No. Zebra are close cousins to horses, which are not cud-chewing animals because none of them have four chambers in their stomachs; just one simple stomach.
Polygastric animals are animals that have four compartments in their stomach. Each compartment is separated by tendons. Sheep and cows are polygastric animals.
