Kinds of BodySubstance :

• Blood (2 facts) - A fluid present in Animals that transports Nutrients to and waste products away from various BodyParts
• Hormone (2 facts) - In Animals, a chemical secreted by an endocrine gland whose products are released into the circulating fluid. Plant hormones or synthetic hormones which are used only to alter or control various physiologic processes, e.g., reproductive control agents, are assigned to the Class PharmacologicSubstance. Hormones act as chemical messengers and regulate various physiologic processes such as growth, reproduction, metabolism, etc. They usually fall into two broad categories, viz. steroid hormones and peptide hormones
• Pigment (4 facts) - A coloring that is present in the Cells of Organisms
• Tissue (5 facts) - An aggregation of similarly specialized Cells and the associated intercellular substance. Tissues are relatively non-localized in comparison to BodyParts, Organs or Organ components. The main features of Tissues are self-connectivity (see SelfConnectedObject) and being a homogeneous mass (all parts in the same granularity are instances of Tissue as well)
