21. Fibroid tumors develop in the uterus.

22. The lymphatic system uses valves to prevent backward flow, similar to the circulatory system.
23. Hemodialysis is a step closer to the need for transplantation compared with peritoneal dialysis. Peritoneal dialysis doesn’t need a dialyzer to work, whereas hemodialysis does.
24. The pituitary gland is involved in the control of antidiuretic hormone.
25. Leukorrhea is a symptom of infection in the .

To find the answer to question 21, we need to know where fibroid tumors develop. The correct answer is B. Uterus. Fibroid tumors are noncancerous growths that occur in the uterus.

To find the answer to question 22, we need to compare the flow of lymph in the lymphatic system with the flow of blood in the circulatory system. The correct answer is C. The lymphatic system uses valves to prevent backward flow. Unlike blood which flows in a closed circuit with the help of a pump (the heart), lymph flows in one direction with the help of valves that prevent it from flowing backward.

To find the answer to question 23, we need to compare hemodialysis and peritoneal dialysis. The correct answer is D. Peritoneal dialysis doesn't need a dialyzer to work, whereas hemodialysis does. Hemodialysis involves the removal of blood from the patient and passing it through a dialyzer to remove waste and excess fluids. Peritoneal dialysis, on the other hand, uses the lining of the abdomen (peritoneum) as a natural filter and doesn't require a dialyzer.

To find the answer to question 24, we need to know which part of the brain is involved in the control of antidiuretic hormone. The correct answer is D. Pituitary. The pituitary gland, which is located at the base of the brain, produces and releases antidiuretic hormone (ADH) which helps regulate water balance in the body.

To find the answer to question 25, we need to know which organ is associated with the symptom of leukorrhea. The correct answer is D. . Leukorrhea is a thick, white or yellowish l discharge that can be a sign of infection or hormonal imbalances in the .
