The human body has a wide range of movement. Much of this movement result from the skeletal system and the muscular system working together. Strong connective tissue called tendons attaches muscles to bone and ligaments attach bone to bone. However, there are several other functions of connective tissue.
Encloses and separates organs.
Loose connective tissue is found around veins, arteries, and organs.
Bones are made of connective tissue and store important nutrients like calcium
Attach muscle to bones and bones to each other.
Tendons and ligaments are made of dense connective tissue and attach muscle to bone and bone to bone.
Transports key nutrients
Blood is made of connective tissue and transport key nutrients around your body.
Adipose connective tissue stores energy
There are Three Key Parts of Connective Tissue: Ground substance, Fibers, Cells
The ground substance consists of large molecules which are abbreviated (GAGs) which link together to form even larger molecules. The GAG stands for Glycosaminoglycans, however, 90% of ground substance is made up of water and fills the spaces between fibers and the cells.
In bones the ground substance also includes minerals.
In blood, the ground substance is plasma
Fibers of connective tissue provide strength, elasticity and support The principal fiber type is collagen. Connective tissue also contains elastic fibers.
Connective tissues contain cells. However, the connective tissue is not directly attached to one another as you would find in epithelial cells.
The fibers and ground substance combined is called the matrix
Cells of connective tissue end with the following suffixes
Blasts: to produce matrix
Cyte: to maintain the matrix
Clast: to destroy the matrix
For example Fibroblast, Fibrocyte, Fibroclast, Osteocyte, Osteoblasts
