Module Two Lesson One Assignment
A connective tissue consists of living cells and non- living substance, various consistencies (fluid, solid, gel-like or very hard), gives the tissue its density. Connects binds and support structures (tendons and ligaments), wraps around organs and protects and cushions them, bear weight, stretch, and take abuse, insulates and fills space and stores fat, transports nutrients and other substances through the body, the supporting framework of our body and protects our organs. There are 5 different kinds of connective tissue; bone, cartilage, dense then loose connective tissue, and blood. The function of bone is it provides protection and support, and stores minerals and is a site of blood cell production. There are 3 types of cartilage; hyaline, elastic, and fibrocartilage. Hyaline covers the end of bones and joints, supporting respiratory passages (trachea). Elastic is found in the larynx (voice box) and the outside of the ear, flexible and elastic. a. Fibrocartilage is tough, having a large number of collagenous fibers, found in the discs between the vertebrae. Dense regular connective tissue is regularly arranged bundles packed with fibers running the same way in one direction. Dense irregular connective tissue is irregularly arranged bundles, with fibers running all directions. There are 3 kinds of loose connective tissue; areolar, adipose, and reticular. Areolar is a loose arrangement of cells and fibers, cushions organs and holds them together. Adipose appears empty, storehouse energy and functions to protect and insulate. Reticular is a delicate network of fibers and cells, located in lymphoid organs (spleen, bone marrow, and lymph nodes provide an internal supporting framework for the lymphoid organs.
