Connective tissue is the tissue of a living organism that does not directly correspond to the work of any organ or organ system, but plays an auxiliary role in all organs, accounting for 60-90% of their mass. Performs basic, protective and trophic functions. Connective tissue has three main components: cells, fibers, and ground substance. Connective tissue is classified into two subtypes: soft and specialized connective tissue. Its main functions are connecting function, keeping water balance, healing function, protection, and trophic function.
