In the process of xenotransplantation, much attention has been given to the study of the pig's heart and human's heart. This is simply due to the fact that there are increasing demands for donations of organs for transplantation in human, and which seems fellow humans are not fully able to meet up. Though there are few similarities between the two hearts, such as;

the two are categorized as mammals, the hearts are divided similarly into the auricular and ventricular chambers, they both have their drainage via the pulmonary arteries, plus aorta into the greater and lesser circulation, but they have differences such as in their physiological functioning and anatomy of their hearts. The left or diagonal branches to conus arteriosus are not recognized in the pig's heart. Meanwhile, they are well recognized in the human's heart. The tubular appendage is present on the right atrium of a pig's heart but present on the left atrium of human's heart.

Many people think that their digestive system is the same as that of animals. However, some people may know or heard that cows have four stomachs, so their digestive system is different from that of a human being. The same can be said about the rat’s digestive system. Whenever you eat food, it must digest. Whether it is a human, a cow, or a rat, the food that these three things eat must digest.

However, there are differences between the human digestive system and a rat digestive system. The social digestive system has a large intestine that are many feet long and wrapped all up in the body. The rat’s digestive system has even larger large intestines than a human. Rats don’t have gallbladders.

Some people assume that agnostics are the same with atheists. There are some differences between these two terms. Agnostics are known to follow the belief of agnosticism which means that they do not believe that humans can actually know more about the spiritual realm because it is only the physical realm that they see. This means that they may not know if gods actually exist or not.

Atheists are people who do not believe that God exists. Take note that Atheists do not believe in any type of god no matter what type of religion may be presented to the atheist. There are some agnostics who may believe in some properties of God but once again, they feel that the other factors are just too far-fetched to grasp.
