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.
The urinary system is comprised of the kidney, ureter, urinary bladder, and urethra. The kidney produces urine, which contains excess water, electrolytes and waste products of the body.It then flows down the ureter into the bladder where it is temporarily stored. The bladder is then emptied via the urethra.The kidney has several important homeostatic, hormonal, and metabolic functions that include:he kidney produces urine, which contains excess water, electrolytes and waste products of the body.
