Which of the following statement is correct? I. Blood is a type of connective tissue II. Bone is a type of connective tissue

Which of the following statement is correct? I. Blood is a type of connective tissue II. Bone is a type of connective tissue Correct Answer Both I and II

Explanation:

  • Bone is the main connective tissue that provides the structural frame to the body.
  • Bones support and protect softer tissues and organs.
  • The bone cells (osteocytes) are present in the spaces called lacunae. 
  • Limb bones, such as the long bones of the legs, serve weight-bearing functions.
  • They also interact with skeletal muscles attached to them to bring about movements.
  • The bone marrow in some bones is the site of the production of blood cells.
  • Blood is a fluid connective tissue containing plasma, red blood cells (RBC), white blood cells (WBC) and platelets.
  • It is the main circulating fluid that helps in the transport of various substances.
  • Connective tissues are most abundant and widely distributed in the body of complex animals.
  • They are named connective tissues because of their special function of linking and supporting other tissues/organs of the body.
  • They range from soft connective tissues to specialized types, which include cartilage, bone, adipose, and blood.
  • In all connective tissues except blood, the cells secrete fibres of structural proteins called collagen or elastin. Hence statement 2 is not correct
  • The fibres provide strength, elasticity and flexibility to the tissue.

So, both blood and bone are the types of connective tissue.
