Final answer:
The matrix in connective tissues provides density and structure, and bone tissue is an example of a tissue with a mostly matrix composition.
Step-by-step explanation:
The matrix in connective tissues is an important component that gives the tissue density and structure. In connective tissues, cells are dispersed in a matrix consisting of living cells and a non-living substance called the ground substance. The ground substance is made of an organic substance, usually a protein, and an inorganic substance, usually a mineral or water. The matrix serves to connect tissues and organs, support the body, and provide flexibility and strength.
One type of tissue that is mostly matrix is bone tissue. Bone is a connective tissue consisting of a rigid, mineralized matrix containing calcium salts, crystals, and osteocytes lodged in lacunae. The matrix provides strength and support to the bone, while the osteocytes maintain the matrix and regulate the mineral content. Bone tissue is highly vascularized and is a major component of the skeletal system.
