• What role does connective tissue play in energy storage?

  It stores energy through fat tissue
• How is connective tissue distributed through the body?

  Adipocytes
• What physiological process results from mast cells production of histamine

  Inflammation
• Which cell type is part of the immune system antibody mediated response

  Plasma cells
• What is the primary role of adipocytes in connective tissue

  Energy storage
• What is the most abundant protein in the human body?

  Collagen
• Which type of connective tissue fiber is characterized by both strength and elasticity, forming a network of fibers in tissues like skin and blood vessel walls?

  Elastic fibres
• What is the key structural arrangement of collagen fibers that contributes to their great strength?
