Which of the following are connective tissues?
Correct answer: D. all the above
- A. cartilage
- B. bone
- C. blood
- D. all the above
Explanation
Cartilage, bone and blood are all connective tissues because they arise from mesenchyme and contain cells embedded in an extracellular matrix. Cartilage and bone provide support, while blood has a fluid matrix for transport and defense. Students may choose bone alone because it is the most familiar connective tissue, overlooking cartilage and blood.
