A histologist observes a connective tissue with an abundant fluid matrix, no fibres, and cells that transport gases and defend the body. This tissue is best classified as:

Answer: Specialised connective tissue.

  • A Dense connective tissue
  • B Specialised connective tissue
  • C Loose connective tissue
  • D Cartilage

Correct answer: B. Specialised connective tissue

Explanation: Blood and lymph are specialised (fluid) connective tissues in which cells float in a liquid matrix without the collagen and elastin fibres of other types.

The four basic animal tissue types and their core functions: epithelial (covering/lining), connective (support and transport), muscular (movement), and neural (signal conduction).

Concept context

The four basic animal tissue types (epithelial, connective, muscular, neural) and the cockroach as a model organism for organ-system level organisation.
