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.
Your kidneys make urine by filtering wastes and extra water from your blood. The urine travels from the kidneys to the bladder in two thin tubes called ureters. The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.
