Connective Tissue Characteristics and Functions

Connective tissue is a diverse and widespread tissue type with three main components: cells, protein fibers, and ground substance. It serves various functions, including protection, support, binding, storage, transportation, and immune defense. Connective tissues are classified into three main types: connective tissue proper, supporting connective tissue, and fluid connective tissue. Connective tissue proper includes loose and dense connective tissues, while supporting connective tissue comprises cartilage and bone. Fluid connective tissue consists of blood and lymph, each with distinct roles in the body.

What are the three main components of connective tissue?

• Protein fibers, blood, and lymph

• Cells, blood vessels, and nerves
