Tissue rejection occurs because the body does not recognize the tissue as compatible. This can be because the proteins are different for example.

Why didn't galen dissect human bodies?

Galen's careful dissection on pigs, dogs and apes meant he discovered lots of new information about anatomy. He dissected some humans but usually had to make do with animals because the Roman traditions and religion were against human dissection. As a result, he had to base his theories about humans on his animal experiments which meant he made mistakes. Some of Galens wrong theories were: 1. The human jaw is made up of two separate bones (it is actually made of one bone). 2. The heart is divided into two parts, each carrying two separate lots around the body. 3. The liver makes up new blood from food.

Why is the fetal pig a good choice to dissect in order to understand human anatomy?

Fetal pigs share many anatomical similarities with humans, making them a good model for studying human anatomy. By dissecting a fetal pig, students can observe the structures and organs in a mammalian body that are relevant to human biology, providing a hands-on learning experience that enhances understanding. Additionally, fetal pigs are readily available, cost-effective, and ethical compared to dissecting human cadavers.

Do pigs eat human flesh?

In the past two decades, I am sure I recall much publicised investigations into and confirming the disposal of human bodies/body parts in a manner ultimately resulting in their consumption by pigs. I have also been told by friends from country/farm areas that pigs are NEVER fed meat scraps for fear they will develop a taste for it- human or otherwise. These animals are apparently very clever and a hungry pig is a formidable animal.
