When you cut the artery that carries blood from the heart, blood spurts out of the heart rhythmically.

the septum does not contain tiny holes to allow mixing of blood from one ventricle to another

anatomy

the study of the structure of living things

vivisection

the use of surgery and untried procedures on living animals
