heart disection

external observation:I never really saw the heart that much but from what I did see it was kind of bloody from the outside and looked like raw meat.

internal observation:
by looking at pictures the heart looked diff than the outside because of all the atriums .The heart looks like it will be soft and mushy from the inside.

 QUESTIONS:

1) The most surprising thing for me was how different it was than I imagined it to be because i thought it would be much more like a soft heart but it looked like a piece of raw meat
2) the atria only has one job to collect and squeeze blood into the ventricles. The ventricles are larger because they need to contract the blood.
3) The left ventricle pumps blood to the entire body while the right only pumps blood to the lungs.
4) The left AV Valves function is to close when the left ventricle contracts to prevent it from back flowing the blood from the left atrium and right AV valves function is to close when the right ventricle contracts. Then the blood from the ventricles can go out of the heart and into the blood vessels. Mitral and tricuspid valves open when the ventricles relax and let blood enter the ventricles from the atria.
