Question

Which type of connective tissue is mainly concerned with immunity?

Answer 1

Hint: All the cells constituting the immunity system formed from the stem cell which is a part of bone marrow. White blood cells (WBC) or leukocytes are the most important cells of the immunity system that destroy the disease-causing microbes and
substances.

Complete answer:
Connective tissue helps in connecting different organs and tissue of the body. They also give support to the different organs, and they are present in every part of the body. They originated from the mesodermal layer. There are different types of connective tissues like cartilage, bone, fat, blood, and lymphatic tissue.

Blood is a special connective tissue which plays a vital role in the immune system. The constituents of the plasma present in blood and cells of the blood . White blood cells help in destroying the foreign particles. Whereas granulocytes and monocytes ingest the dead cells and bacteria and other foreign particles and protect our body from them. The lymphocytes present in blood help in producing antibodies against the invading microbes.
Thus, we can say that blood has a main role in the formation of our immunity system. The cells of blood interact with each other in a complex way to form the total immunity system of our body.

Note:
Connective tissue helps in connecting different organs and tissue, it gives support to the different organs of the body. They are made up of gel, fibres, and different types of cells. They show strength and elasticity due to the presence of these fibres. Blood is a fluid connective tissue whose cells help in both innate and acquired immunity.
