Humans and lions are both mammals.
Characteristics of mammals are:
All mammals reproduce by giving birth to their young.
All mammals feed their young ones with milk.
All mammals have hairs on their body.
Therefore if the two are classified in the MAMMALS section so their bodies must be the same.
From my opinion humans and mammals have the same digestive system.
Humans and mammals can't have the same digestive system as humans eat plants (we are omnivores) and lions eat meat (carnivore). Therefore we have different digestive needs, our intestinal tract would be longer than that of any carnivore (so we can get the most nutrients out of the food we eat, whereas a carnivore needs a shorter digestive tract so the meat doesn't go rotten inside it's intestine).
Seriously think about it, cows are mammals as well but they have four stomachs (because they are herbivores)!
most primates.
They both love food!
There are many differences and similarities between a perch and a human in the digestive system. One is the enzymes found in the gut.

The main similarities between koala and human digestive systems are the basic organs of oesophagus, stomach, liver, etc. Koalas have a different digestive system and metabolism which enables them to digest gum leaves. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala has developed a stomach which is capable of removing the toxins from where they are filtered out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The caecum is similar to the human appendix.
There are many similarities between fish and humans. Fish and humans have many of the same organs. We both have a digestive system and a reproductive system.
Difference between a human being and an elephants digestive system?
Koalas have a system that helps them digest the eculeptas leaves but we do not.
nothing, a fish is slightly smaller
A polar bear's digestive system is a digestive system and a humming bird is a humming bird.
similarities between kangaroo and human
one is a turtle and the other is straight
Both species have the same organs as the other in their digestive system: mouth, esophagus, stomach (in cows, the part of the four-chambered stomach that have similar digestive enzymes to a human's is called the Abomasum), liver, spleen, pancreas, large and small intestines, colon, rectum, anus, etc.
Similarities between a pig and human reproductive system include the testis, penis, and prostate. In addition, both have a uterus and fallopian tubes.
