2. Nausea, indigestion, heartburn or abdominal pain.

Why does the heart have a thick and thin side?

The thick side of the heart is full of muscle. The thick side of the heart is also the side with all of the arteries. It needs all of this muscle to pump blood all around the body through the arteries. The arteries pump oxegynated blood away from the heart. 

Random fact: 

Oxegynated blood is red and de-oxegynated blood is blue. oxegynated blood goes away from the heart through the arteries and de-oxegynated blood comes back to the heart through the veins.

How do we know what part of the heart is Fat

The fat in the heart is the colour white and the muscly part of the heart is red.

Valves

The valves let blood flow to the atria and the ventricles.

Labelled two top holes

The two labelled holes in the heart are right Aorta and the Superior Venacava.

Pigs vs sheep heart

Pigs hearts are like humans heart they look very similar and work very similar. They have four holes like human hearts. Whereas sheep hearts look like a huge mess the capillaries just go everywhere. By everywhere I mean they just look like strings going down the heart.

Random facts: 

1. Your heart will beat about 115,000 times a day.

2. Your heart pumps about 2,000 gallons a day of blood.
