The model meshes include adult circulation versus circulation in Tetralogy of Fallot (TAF), arrow & text labels. The blood flow in a patient with Tetralogy of Fallot is outlined. To contrast it to normal blood circulation a separate model of normal circulation is included. The Tetralogy of Fallot (OVER RIDING OF AORTA, PUL STENOSIS, VENTRICULAR SEPTAL DEFECT, RIGHT VENTRICULAR HYPERTROPHY), fossa, ligament teres, venosus & arteriosus are duly depicted with proper labelling & blood flow directional arrows. Excellent model for teaching, demonstration and knowlegde of human body. The models include both procedural and image textures blend files separately. The texture file include diffuse, roughness and normal png and jpeg based on non overlapping UV maps. The formats 3mf, ply, obj, fbx with applied uv mapped textures have also been included in the downloads along with stl. I have included the various formats needed by various customer for the various 3d modelling softwares. formats compressed in rar formats
