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.
Urine is produced by your kidneys as they filter water and wastes out of your blood. From the kidneys, urine drains down paired tubes called ureters into your bladder for storage. When it is time to urinate, urine flows from your bladder through your urethra to the outside. Changes in urine color can be related to the concentration of the urine, substances filtered into the urine, or conditions of the urinary tract. Concentrated urine can have a brownish appearance, as can blood in your urine.
