The urethra is longer in which gender? Male Female Both are the same length It depends on age None 11. Which of the following is a normal anatomical constriction of the ureter where a kidney stone is most likely to lodge? At the hilum of the kidney At the crossing of the ureter over the iliac vessels At the level of the renal pelvis At the bladder trigone None 12. The ureter is lined internally by which type of epithelium? Simple squamous epithelium Pseudostratified columnar epithelium Transitional epithelium (urothelium) Stratified squamous epithelium None 13. Which part of the nephron contains the glomerulus and is responsible for the initial filtration of blood? Proximal convoluted tubule Loop of Henle Distal convoluted tubule Renal corpuscle None 14. The proximal convoluted tubule is lined by which type of epithelial cells?

Which of the following organs lies directly anterior to the right kidney? Spleen Stomach Liver Pancreas None 17. Which artery primarily supplies blood to the kidneys? Inferior mesenteric artery Renal artery Common iliac artery Suprarenal artery None 18. The ureter passess through which of the following layer before entering in the urinary bladder? Peritoneum only Muscular layer of the bladder wall Serosa only Renal cortex None 19. Where are the kidneys located in the human body? In the pelvic cavity, lateral to the bladder Retroperitoneal, on either side of the vertebral column between T12 and L3 vertebrae Intraperitoneal, in the lower abdomen near the iliac crest Within the thoracic cavity, below the diaphragm None 20. Which of the following statements about the course of the ureter is TRUE? The ureter lies anterior to the psoas major muscle. The ureter crosses posterior to the uterine artery in females. The ureter enters the bladder through the trigone vertically. The ureter has no anatomical constrictions along its path. None 21. why the kidney is called “kidney” (based on its shape and origin): Why is the kidney named “kidney”? Because it filters blood Because its shape resembles a small “kid" Because it produces urine Because it is located near the ribs None 22.
