COMPARING/CONTRASTING TIME!!!!The pig’s digestive system and human’s digestive system are not very different. Both it’s structure and it’s function are similar. The pig’s intestines, however, are a little bit bigger than a human’s. Pigs and humans are similiar because they both have monogastric digestive systems.

FUN FACTS TIME!!! Pigs are omnivors, they eats plants AND MEAT!!! what if they ate eachother…

Well that’s it! Bye!

The skeletal system keeps the body structured. It is made up of bones that protect the organs. The human and pig skeletons are similar because they both have the same major bones like the skull, spine, femur, and jaw. Some of the differences are that they have hooves, their skulls are shaped differently, and they have many small bones while humans have many large bones. One of the major differences is that humans stand on two feet and have upright body structures and pigs stand on four legs. The function of the pig’s skeletal system is the same as a human: it keeps the body structured and protects the internal organs. The size of the skeletal system is smaller than a human. The structure of the skeletal system is very similar to the human skeletal system.

The muscular system controls the actions of your muscles allowing your body to move. In vertebrates the musculatory system controlled by the nervous system.
The musculatory system in a human is very similar to that of a fetal pig. Most variations are in the size and locations of the muscles. They have the same major thigh muscles, also pigs are quadrupedal and humans are bipedal. They have the same major chest/abdominal muscles.
An interesting fact is that the heart and lungs of the fetal pigs are also involuntary actions controlled by the brain, just as in humans.

The lymphatic system carries blood from tissues that have recently been soaked. The blood is then called lymph. The result of these actions balances the fluids in the body and helps absorb nutrients in the small intestine. The lymphatic system often works very closely with the cardiovascular system.

There were no significant differences. That was our interesting fact: no differences.

The human cardiovascular system is very similar to the cardiovascular system of the fetal pig. Both the human and pig have four-chambered hearts and multi-lobed lungs. Humans have three lobes in the right lung and two in the left lung. In pigs, the right lung has four lobes and the left has two or three.

Unlike pigs, humans do not have a bicarotid trunk. The bicarotid trunk in pigs splits into the right and left common carotid arteries. In humans, the left common carotid artery branches from the aorta, while the right common carotid artery originates from the brachiocephalic artery.

Pigs also do not have the common illiac artery present in humans. In a human, the common illiac artery splits into internal and external illiac arteries. In a pig, the external and internal illiac arteries split directly from the aorta.

We couldn’t really find any interesting facts about pig cardiovascular systems on the websites… it was a struggle to find similarities and differences in the first place.

The Urinary and Excretory Systems in both humans and pigs are meant to do one thing, eliminate waste. This is done through the kidneys. The kidneys produce urine, which carries the wastes from the body.

The pig and human Excretory Systems are mainly the same. One main difference is that the pig’s organs (kidneys and tubes) are much smaller. The pig holds less waste, therefore this size is appropriate. As for how they work, they both do as stated before – eliminate waste.

Fun Fact: The kidneys are similar to beans in structure and color.
