Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. The Urinary system consists of Two bladders,two kidneys,one ureter, one urethra Two bladders, two kidneys, two ureters, one urethra One bladder, two kidneys, one ureter, two urethras One bladder, two kidneys, two ureters, one urethra2. Which product, secreted by the kidney, helps regulate blood pressure? Cortisol Aldosterone Antidiuretic hormone Renin3. Which section of the Nephron is primarily responsible for concentrating the urine? Distal convoluted tubule Glomerulus Loop of Henle Proximal Convoluted tubule4. The removal of nitrogenous wastes is called as Excretion Defecation Breathing Sweating5. A tube that arises from the kidney and connects behind with the urinary bladder is called Urethra Pelvis Renal tubule Ureter6. Which of the following organs is the storage area of urine? Kidney Ureter Urethra Urinary bladder7. Choose the Odd one out Sweat Saliva Urine Tears8. The apex of each pyramid which projects into the pelvis of the kidney is called Pyramid Medulla Papilla Calyx9. Maximum amount of water from glomerular filtrate is reabsorbed in Distal convoluted tubule Proximal convoluted tubule Ascending limb of loop of Henle Descending limb of loop of Henle10. Where does blood go after it leaves the glomerulus? It re-enters pulmonary circulation It returns to the heart via the inferior vena cava It runs parallel to the nephron via the efferent arterioles It runs parallel to the nephron via the efferent venules11. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Cecum Villus Sphincter Appendix12. Ultrafiltration occurs in Distal convoluted tubule Henle's loop Proximal convoluted tubule Bowman's capsule13. Excretion primarily involves Removal of all by-products during catabolism All of the above Removal of by-products during anabolism Removal of nitrogenous waste14. What is the chief nitrogenous waste in mammals? Ammonia Urea Uric acid Amino acid15. Profuse sweating takes place during heavy muscular exercise. The reason is To eliminate excessive lactic acid produced due to anaerobic metabolism To regulate the temperature of the body To excrete excess amount of sodium chloride All of these16. The bowman's capsule and the glomerulus together are called Renal capsule Malpighian capsule or Renal capsule Malpighian capsule Renal tubule17. Which of the following are located in the cortex of the kidney? Ascending limb, descending limb and collecting duct Glomerulus and Proximal tubule Loop of Henle Glomerulus, PCT and DCT18. The structural and functional unit of kidney is Neuron Urine Nephron Ureter19. What is located within the glomerular capsule? Several conducting ducts Loop of Henle Renal cortex A knot of capillaries20. The consumption of alcohol has what effect on the human urinary system? It decreases the activity of antidiuretic hormone(ADH), increasing urine production It increases the activity of antidiuretic hormone(ADH), decreasing urine production It results in dark, concentrated urine It completely blocks the flow of fluids through the kidney tubules21 out of Time is Up!
