It is due to these limitations in the polysaccharide vaccines, the inconsistent responses of children to polysaccharide antigens and the differences between adult and child defence mechanisms and actions in response to these bacterium that led to the development of polysaccharide-protein conjugate vaccines.hese types of inactivated vaccines may be protein or polysaccharide based. âProtein-based vaccines may include toxoids (which is a form of inactivated bacterial toxin) and subunit or subvirion products.
Storage and Excretion of Wastes. After urine has been produced by the kidneys, it is transported through the ureters to the urinary bladder. The urinary bladder fills with urine and stores it until the body is ready for its excretion.
Normally, only water soluble substances are excreted in the urine. Urine is produced by the kidneys as a process of cleaning the blood and excreting the unwanted soluble waste products from the body. The kidneys filter out the waste products such as toxins, excess water and mineral salts from the bloodstream.
