As you can guess from the name itself that, connective tissue serves a "connecting" function. Connective tissue is a type of tissue made up of mainly fibers forming a framework and support structure for body tissues and organs. It is the material between the cells of the body that gives tissues form and strength. Many organs, joints, etc are surrounded by various connective tissues, they protect them from sudden tearing external forces, excessive stretching, etc. Cartilage, ligament, tendon, etc are a few examples of connective tissue. Connective tissues have three main components which are:- 1. Fiber 2. Ground Substance 3. Cells There are mainly three types of fibers which are:- 1. Collagenous Fiber Collagen fiber is the fiber in the extracellular matrix of connective tissues characterized by being elongated. It is typically arranged in branching bundles of indefinite length. It is a strong, flexible, and insoluble fiber. It occurs in the tendon, ligaments, bone, cartilage, etc. 2. Elastic Fiber Elastic fibers are an essential component of the extracellular matrix composed of elastin (a special kind of protein). These fibers are able to stretch many times their length and snap back to their original length when relaxed without loss of energy. They give a recoil effect specially to your arteries and lungs. They are also known as yellow fibers. 3. Reticular Fiber Reticular fiber forms a platform for other cells and acts as a supporting mesh in soft tissues. It is made up of type III collagen fiber and is found in our liver, bone marrow, lymphatic organs, etc. Ground substances are the shapeless, formless, gel-like, noncellular component of the extracellular matrix where the fibers and cells of connective tissue are fixed firmly. It is a transparent material with the properties of a viscous solution or a highly hydrated thin gel, thus due to this property it provides lubrication for collagen fibers and it fills the spaces between fibers and cells. Our body cells utilize these ground substance for water storage, support system, binding agent, and as a medium which can perform intercellular exchange (Intercellular exchange means it transfer information from one cell to another one, mainly it carry the information from between blood cells and other types of cells). Dense connective tissue has a smaller amount of ground substance compared to the fibrous material. Ground substance is primarily composed of water and large organic molecules, such as glycosaminoglycans, proteoglycans, and glycoproteins. The cells are the basic structural, and functional unit of a living organism. There are many types of cells like fibroblast cells, adipose cells, adipocytes, macrophage cells, etc. Cells can acquire specified functions and carry out various tasks within the cell such as replication, DNA repair, protein synthesis, and motility. Cells are of two types: 1. Eukaryotic, which contains a nucleus 2. Prokaryotic cells, which do not have a nucleus, but a nucleoid region is still present. Prokaryotes are single-celled organisms, while eukaryotes may be either single-celled or multicellular. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature. These cells cooperate with other specialized cells and become the building blocks of large multicellular organisms, such as humans and other animals. Although cells are much larger than atoms, they are still very small. Most cells are measured in micrometers due to their small size. The cells of connective tissue include two types that are relatively stationary 1. fibroblasts  2. Adipose cells. There are also several types of motile migrating cells mast cells, macrophages, monocytes, lymphocytes, plasma cells, and eosinophils. Fibroblasts are the most common cell type of connective tissue. They produce both fibers and amorphous ground substances.
