Blood is a type of which tissue?

• A. Epithelial tissue
• B. Connective tissue
• C. Muscular tissue
• D. Nervous tissue

Answer: (B)

Blood is a specialized connective tissue because its cells are suspended in a liquid extracellular matrix called plasma. In connective tissues, the matrix is what supports and surrounds the cells, and in blood the plasma carries red and white blood cells and platelets, functioning as the transport medium. Blood also comes from mesoderm during development and serves key roles in transport, immunity, and clotting, which fits the broader concept of connective tissues that connect, support, or transport within the body. This classification contrasts with epithelial tissue, which lines surfaces and forms tightly joined layers; muscular tissue, which is built for contraction; and nervous tissue, which specializes in transmitting electrical signals. The liquid matrix of blood and its circulating cells are the hallmark that places it in the connective tissue family rather than those other tissue types.
