Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. What is located within the glomerular capsule? Loop of Henle Several conducting ducts A knot of capillaries Renal cortex2. The Urinary system consists of One bladder, two kidneys, one ureter, two urethras Two bladders,two kidneys,one ureter, one urethra One bladder, two kidneys, two ureters, one urethra Two bladders, two kidneys, two ureters, one urethra3. 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 runs parallel to the nephron via the efferent arterioles It re-enters pulmonary circulation4. The consumption of alcohol has what effect on the human urinary system? It results in dark, concentrated urine It decreases the activity of antidiuretic hormone(ADH), increasing urine production It completely blocks the flow of fluids through the kidney tubules It increases the activity of antidiuretic hormone(ADH), decreasing urine production5. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Sphincter Cecum Appendix Villus6. A tube that arises from the kidney and connects behind with the urinary bladder is called Ureter Pelvis Renal tubule Urethra7. Choose the Odd one out Saliva Tears Urine Sweat8. Which section of the Nephron is primarily responsible for concentrating the urine? Loop of Henle Glomerulus Proximal Convoluted tubule Distal convoluted tubule9. Excretion primarily involves All of the above Removal of all by-products during catabolism Removal of by-products during anabolism Removal of nitrogenous waste10. Ultrafiltration occurs in Proximal convoluted tubule Henle's loop Distal convoluted tubule Bowman's capsule11. Which of the following organs is the storage area of urine? Kidney Urethra Urinary bladder Ureter12. The structural and functional unit of kidney is Nephron Ureter Neuron Urine13. The removal of nitrogenous wastes is called as Breathing Defecation Excretion Sweating14. 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 tubule15. The apex of each pyramid which projects into the pelvis of the kidney is called Papilla Medulla Calyx Pyramid16. What is the chief nitrogenous waste in mammals? Ammonia Uric acid Urea Amino acid17. The bowman's capsule and the glomerulus together are called Malpighian capsule Renal capsule Renal tubule Malpighian capsule or Renal capsule18. Profuse sweating takes place during heavy muscular exercise. The reason is All of these To excrete excess amount of sodium chloride To eliminate excessive lactic acid produced due to anaerobic metabolism To regulate the temperature of the body19. Which product, secreted by the kidney, helps regulate blood pressure? Renin Aldosterone Antidiuretic hormone Cortisol20. Maximum amount of water from glomerular filtrate is reabsorbed in Descending limb of loop of Henle Distal convoluted tubule Proximal convoluted tubule Ascending limb of loop of Henle21 out of Time is Up!
