Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Which of the following organs is the storage area of urine? Ureter Kidney Urinary bladder Urethra2. The apex of each pyramid which projects into the pelvis of the kidney is called Papilla Medulla Pyramid Calyx3. The consumption of alcohol has what effect on the human urinary system? It increases the activity of antidiuretic hormone(ADH), decreasing urine production It completely blocks the flow of fluids through the kidney tubules It decreases the activity of antidiuretic hormone(ADH), increasing urine production It results in dark, concentrated urine4. Which of the following are located in the cortex of the kidney? Ascending limb, descending limb and collecting duct Loop of Henle Glomerulus, PCT and DCT Glomerulus and Proximal tubule5. Which section of the Nephron is primarily responsible for concentrating the urine? Distal convoluted tubule Glomerulus Loop of Henle Proximal Convoluted tubule6. The structural and functional unit of kidney is Neuron Nephron Ureter Urine7. Ultrafiltration occurs in Proximal convoluted tubule Bowman's capsule Henle's loop Distal convoluted tubule8. Excretion primarily involves All of the above Removal of all by-products during catabolism Removal of nitrogenous waste Removal of by-products during anabolism9. Where does blood go after it leaves the glomerulus? It re-enters pulmonary circulation It runs parallel to the nephron via the efferent arterioles It returns to the heart via the inferior vena cava It runs parallel to the nephron via the efferent venules10. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Villus Appendix Sphincter Cecum11. What is the chief nitrogenous waste in mammals? Urea Ammonia Amino acid Uric acid12. The bowman's capsule and the glomerulus together are called Renal tubule Malpighian capsule Renal capsule Malpighian capsule or Renal capsule13. The Urinary system consists of Two bladders,two kidneys,one ureter, one urethra One bladder, two kidneys, two ureters, one urethra One bladder, two kidneys, one ureter, two urethras Two bladders, two kidneys, two ureters, one urethra14. Maximum amount of water from glomerular filtrate is reabsorbed in Proximal convoluted tubule Ascending limb of loop of Henle Distal convoluted tubule Descending limb of loop of Henle15. Profuse sweating takes place during heavy muscular exercise. The reason is To excrete excess amount of sodium chloride To regulate the temperature of the body All of these To eliminate excessive lactic acid produced due to anaerobic metabolism16. A tube that arises from the kidney and connects behind with the urinary bladder is called Ureter Renal tubule Urethra Pelvis17. Which product, secreted by the kidney, helps regulate blood pressure? Aldosterone Renin Cortisol Antidiuretic hormone18. Choose the Odd one out Tears Sweat Urine Saliva19. What is located within the glomerular capsule? Loop of Henle Several conducting ducts Renal cortex A knot of capillaries20. The removal of nitrogenous wastes is called as Sweating Excretion Breathing Defecation21 out of Time is Up!
