Question

Which of the following can be related to the tissue called blood?

• A. It has a fibre-free matrix but rich in collagen protein
• B. It has both nucleated and non-nucleated cells, performing aerobic respiration
• C. Blood is a specialised connective tissue
• D. It is a form of dense connective tissue, having dense arrangement due to large count of RBCs

Answer 1

Answer: (C)

Connective tissue is the most abundant tissue in animals. This tissue is further divided into three types: Loose connective tissue, dense connective tissue, and specialized connective tissue. Loose connective tissue shows a matrix with cells and fibers. These are areolar and adipose tissue. Dense connective tissues are tendons and ligaments. These are known as dense as fibers and cells are densely packed in the matrix. Specialized connective tissues are fluid connective tissues or supporting connective tissues. Fluid connective tissues are blood and lymph as these are fluid and thus fibres are absent. Supporting connective tissues include bone and cartilage as these have lacunae.
