Marfan syndrome and epidermolysis bullosa (EB) are two inherited connective tissue illnesses. It gives the skin suppleness and, because it contains multiple types of cells, it aids in the defense against bacteria and other substances, forming a physical and chemical barrier that protects essential organs. The fibrous components of loose areolar connective tissue, when viewed with the light microscope, appear as colourless strands of varying diameter running in all directions, and, if not under tension, these have a slightly undulant course. These cells also release modified polysaccharides, which collect between cells and fibers and serve as a matrix (ground substance). Another vital nutrient that helps to support healthy connective tissue is . The human body is made up of billions of cells that work together to execute numerous jobs. Matrix, cells, and fibres are the three components. Choose all that apply. This cookie is set by GDPR Cookie Consent plugin. Connective tissues can have various levels of vascularity.
