What are the different types of connective tissues?

The types of connective tissues include: adipose tissue, dense fibrous connective tissue, blood, cartilage, adipose tissue, loose connective tissue, and osseous tissue. 

• Blood is composed of a liquid extracellular matrix in which cells circulate. It consists of plasma (its fluid matrix) and specialized cells (red blood cells, white blood cells, and platelets). The main function of blood is to transport oxygen (via red blood cells) and nutrients to cells. 
• Adipose tissue is primarily composed of adipocytes and serves as a site for energy storage. 
• Dense fibrous tissue is composed of densely packed type I collagen fibers. This tissue provides strength as it forms the tendons and ligaments in the body.
• Cartilage is a firm and flexible connective tissue with a rubbery matrix. It cushions and supports structures such as the joints, ears, and nose. 
• Loose connective tissue has loosely arranged collagen and elastic fibers, with cells suspended in a gel-like matrix. This type of tissue functions to hold organs, tissue, and anatomic structures in place. 
• Osseous tissue is composed of a mineralized matrix containing calcium and collagen fibers. It functions to support and protect soft tissues, phosphate, and calcium, as well as the harboring of bone marrow.
