Collagen is the connective tissue in blood
Collagen weakens the cells lining the blood vessels
Collagen is in the connective tissue surrounding blood vessels
Collagen causes blood vessels to become stiff and more likely to break
Collagen inhibits blood clotting
Increased blood flow to the skin
Increased flexibility in the skin
Changes in the skins cell type from squamous to columnar
Changes in the skin cell type from columnar to squamous
Less flexibility in the skin
Allow exchange of substances by diffusion and osmosis
Protect areas subject to abrasion
Secrete and absorb substances
Secrete hormones
Secrete and propel mucous
