Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. The bowman's capsule and the glomerulus together are called Malpighian capsule Renal tubule Malpighian capsule or Renal capsule Renal capsule2. Profuse sweating takes place during heavy muscular exercise. The reason is To eliminate excessive lactic acid produced due to anaerobic metabolism All of these To excrete excess amount of sodium chloride To regulate the temperature of the body3. Which of the following organs is the storage area of urine? Kidney Urethra Urinary bladder Ureter4. What is the chief nitrogenous waste in mammals? Uric acid Amino acid Ammonia Urea5. A tube that arises from the kidney and connects behind with the urinary bladder is called Pelvis Ureter Urethra Renal tubule6. Which section of the Nephron is primarily responsible for concentrating the urine? Glomerulus Proximal Convoluted tubule Distal convoluted tubule Loop of Henle7. Where does blood go after it leaves the glomerulus? It re-enters pulmonary circulation It runs parallel to the nephron via the efferent venules It runs parallel to the nephron via the efferent arterioles It returns to the heart via the inferior vena cava8. Excretion primarily involves Removal of all by-products during catabolism Removal of by-products during anabolism Removal of nitrogenous waste All of the above9. Maximum amount of water from glomerular filtrate is reabsorbed in Proximal convoluted tubule Descending limb of loop of Henle Distal convoluted tubule Ascending limb of loop of Henle10. The Urinary system consists of One bladder, two kidneys, one ureter, two urethras One bladder, two kidneys, two ureters, one urethra Two bladders, two kidneys, two ureters, one urethra Two bladders,two kidneys,one ureter, one urethra11. The removal of nitrogenous wastes is called as Sweating Excretion Defecation Breathing12. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Villus Sphincter Cecum Appendix13. Choose the Odd one out Tears Urine Sweat Saliva14. The consumption of alcohol has what effect on the human urinary system? It decreases the activity of antidiuretic hormone(ADH), increasing urine production It completely blocks the flow of fluids through the kidney tubules It results in dark, concentrated urine It increases the activity of antidiuretic hormone(ADH), decreasing urine production15. What is located within the glomerular capsule? Several conducting ducts Renal cortex Loop of Henle A knot of capillaries16. Which product, secreted by the kidney, helps regulate blood pressure? Cortisol Aldosterone Antidiuretic hormone Renin17. The structural and functional unit of kidney is Ureter Urine Neuron Nephron18. Ultrafiltration occurs in Distal convoluted tubule Proximal convoluted tubule Henle's loop Bowman's capsule19. Which of the following are located in the cortex of the kidney? Glomerulus, PCT and DCT Glomerulus and Proximal tubule Ascending limb, descending limb and collecting duct Loop of Henle20. The apex of each pyramid which projects into the pelvis of the kidney is called Pyramid Medulla Papilla Calyx21 out of Time is Up!
