Enlarged. Sectioned so that both ventricles and atria open to expose the valves. Large blood vessels near the heart and musculature of the heart are shown. Separates into 7 parts.
Flexible bond, 90mm (double bonding), Packs of ten 90mm flexible bonds to represent double bonding, Use to supplement your Unit building sets or for building custom models
Molecular Geometry Set (VSEPR), Five universal VSEPR models allows the student to build linear, planar triangular, tetrahedral, trigonal bipyramidal, octahedral structures, When Student builds the molecules over a white paper and white links it can be easily visualized
