The correct option is A-3, B-4, C-2, D-1
Explanation
The Connective Tissues in animals. These tissues are classified based on the physical nature of their intercellular matrix (fluid, jelly-like, dense, or rigid) and the specific cells embedded within it.- A. Blood (Matches 3): Blood is a fluid connective tissue. Its matrix is a liquid called plasma, which transports gases, digested food, hormones, and waste materials. Red blood cells, white blood cells, and platelets are suspended in this fluid matrix.
- B. Bone (Matches 4): Bone is a strong and non-flexible tissue that forms the structural framework of the body. Its matrix is hard and rigid, primarily composed of calcium and phosphorus compounds.
- C. Cartilage (Matches 2): Cartilage is a specialized connective tissue with widely spaced cells. Its matrix is solid yet pliable (flexible), composed of proteins and sugars. It is found in the nose, ear, trachea, and larynx, and it smoothes bone surfaces at joints.
- D. Areolar (Matches 1): Areolar tissue is a loose connective tissue found between the skin and muscles, around blood vessels, and in bone marrow. Its matrix is jelly-like, and it functions to fill the space inside organs, supporting internal structures and aiding in tissue repair.
Key Takeaway: The primary distinction between different connective tissues lies in the composition and physical state of their extracellular matrix: Plasma (Fluid), Calcium/Phosphorus (Hard), Proteins/Sugars (Solid/Pliable), or Jelly-like (Loose).
