Question

Which of the following tissues has the minimum intercellular matrix?
A. Blood
B. Bone
C. Cartilage
D. Areolar tissue

Answer 1

Blood, bone, and cartilage are the types of specialized connective tissue. Among these three specialized connective tissues, blood is fluid connective tissue while bone and cartilage are skeletal connective tissue. Areolar tissue is loose connective tissue. The intercellular matrix is non-living substances released by the cell to fill the gaps between the cells of the tissue.

Complete step by step answer: Blood is made up of fiber-free fluid matrix and specialized living cells that can neither divide nor secrete matrix. Blood consists of plasma and formed elements that include red blood cells (RBCs) also called erythrocytes, white blood cells (WBCs) also called leukocytes, and platelets which are also termed as thrombocytes.
Cartilage is the elastic tissue and is harder than the dense connective tissue but softer than the bone. The matrix which is also called the ground substance of cartilage is solid and pliable and resists compression. In the matrix, there is a fluid-filled cavity present and that cavity is called lacunae. Lacunae consist of a special type of cell called chondrocytes, which forms the cartilage. Also, the matrix is produced and maintained by the cartilage cells.
Areolar tissue is the most widely distributed connective tissue in the body of an animal. This tissue consists of the ground substance also called the matrix which is made up of modified polysaccharides (mucopolysaccharide) and proteins (glycoproteins). Also scattered in the matrix are several kinds of irregular cells, which perform different functions in the body and some of these cells are Fibroblasts, Macrophages or Histiocytes, Mast cells, and Plasma cells.
And Bone is hard connective tissue and is very strong and non-flexible tissue. This tissue is made up of $70\%$ organic matter and $30\%$ inorganic matter. Matrix of bone is very hard as it is made up of calcium phosphate, calcium carbonate, etc., and proteins like ossein and collagen fibers. Calcium salts and collagen fibres give strength to the bone.
So by considering the above points the correct answer to the given question is option B. Bone.

Note: In the bone, a solid matrix is present and consists of longitudinal canals which are called Haversian canals. This Haversian canal consists of the artery, vein, lymph vessel, a nerve, and some bone cells. And, these canals are features of the long bones of mammals.
