Neco 2019 Biology Question 47
Practice objective / multiple choice question 47 from the 2019 Neco Biology examination.
The diagram shows the urinary system of a human, including the renal pelvis, a ureter of total length 30 cm with three peristaltic constrictions, the urinary bladder and the urethra. Urine leaves the renal pelvis and travels down the ureter at an initial speed of 0.6 cm/s. Each constriction reduces the speed of urine flow in the subsequent segment by 15% relative to the speed in the preceding segment. Assuming the ureter is divided into three equal-length segments between the constrictions, calculate the total time (in seconds) required for urine to travel from the renal pelvis to the bladder.
