2
Sulci found between the ventria - they are shallow depression
Called the anterior and posterior interventricular sulci
How does excitation in the heart spread?
2
The SA node passes signal to atrial muscle and also to the AV node

Papillary muscles
What are the strings you see in the heart?
Chordae tendineae/heart strings

What type of valve is found between the right atrium and ventricle?
