Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Excretion primarily involves All of the above Removal of all by-products during catabolism Removal of nitrogenous waste Removal of by-products during anabolism2. Choose the Odd one out Saliva Tears Sweat Urine3. Which product, secreted by the kidney, helps regulate blood pressure? Antidiuretic hormone Renin Cortisol Aldosterone4. Which of the following organs is the storage area of urine? Kidney Urinary bladder Ureter Urethra5. The bowman's capsule and the glomerulus together are called Renal capsule Malpighian capsule or Renal capsule Malpighian capsule Renal tubule6. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Cecum Sphincter Villus Appendix7. Ultrafiltration occurs in Henle's loop Distal convoluted tubule Proximal convoluted tubule Bowman's capsule8. 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 All of these To excrete excess amount of sodium chloride9. Which of the following are located in the cortex of the kidney? Loop of Henle Ascending limb, descending limb and collecting duct Glomerulus, PCT and DCT Glomerulus and Proximal tubule10. What is the chief nitrogenous waste in mammals? Amino acid Ammonia Urea Uric acid11. The consumption of alcohol has what effect on the human urinary system? It results in dark, concentrated urine It increases the activity of antidiuretic hormone(ADH), decreasing urine production It decreases the activity of antidiuretic hormone(ADH), increasing urine production It completely blocks the flow of fluids through the kidney tubules12. The structural and functional unit of kidney is Urine Ureter Neuron Nephron13. The apex of each pyramid which projects into the pelvis of the kidney is called Medulla Papilla Pyramid Calyx14. Where does blood go after it leaves the glomerulus? It runs parallel to the nephron via the efferent venules It returns to the heart via the inferior vena cava It re-enters pulmonary circulation It runs parallel to the nephron via the efferent arterioles15. The removal of nitrogenous wastes is called as Sweating Breathing Excretion Defecation16. The Urinary system consists of One bladder, two kidneys, one ureter, two urethras Two bladders,two kidneys,one ureter, one urethra Two bladders, two kidneys, two ureters, one urethra One bladder, two kidneys, two ureters, one urethra17. What is located within the glomerular capsule? A knot of capillaries Several conducting ducts Loop of Henle Renal cortex18. A tube that arises from the kidney and connects behind with the urinary bladder is called Pelvis Urethra Renal tubule Ureter19. Which section of the Nephron is primarily responsible for concentrating the urine? Distal convoluted tubule Proximal Convoluted tubule Glomerulus Loop of Henle20. Maximum amount of water from glomerular filtrate is reabsorbed in Proximal convoluted tubule Descending limb of loop of Henle Ascending limb of loop of Henle Distal convoluted tubule21 out of Time is Up!
