In this video, you will see my class dissecting a pig's heart. This is what I think about the pig's heart. The muscle of the heart is very strong so it can pump blood around the whole body for years. There are two tubes in the heart. One tube is for taking the blood in and the other is pumping the blood out. The smooth tissue help pump the blood out smoothly. The valves is where they help lead the blood in and pump the blood out. There are tendons in the heart to help keep it closed. Enjoy the video!
