Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Ultrafiltration occurs in Distal convoluted tubule Proximal convoluted tubule Henle's loop Bowman's capsule2. Which of the following organs is the storage area of urine? Urinary bladder Kidney Urethra Ureter3. Excretion primarily involves Removal of by-products during anabolism All of the above Removal of nitrogenous waste Removal of all by-products during catabolism4. 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 metabolism5. The apex of each pyramid which projects into the pelvis of the kidney is called Calyx Medulla Pyramid Papilla6. The bowman's capsule and the glomerulus together are called Malpighian capsule or Renal capsule Renal capsule Malpighian capsule Renal tubule7. 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 Henle8. The consumption of alcohol has what effect on the human urinary system? 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 urine It increases the activity of antidiuretic hormone(ADH), decreasing urine production9. Which of the following are located in the cortex of the kidney? Loop of Henle Ascending limb, descending limb and collecting duct Glomerulus and Proximal tubule Glomerulus, PCT and DCT10. A tube that arises from the kidney and connects behind with the urinary bladder is called Renal tubule Urethra Ureter Pelvis11. The removal of nitrogenous wastes is called as Defecation Sweating Excretion Breathing12. What is located within the glomerular capsule? Renal cortex Several conducting ducts Loop of Henle A knot of capillaries13. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Villus Appendix Cecum Sphincter14. What is the chief nitrogenous waste in mammals? Urea Amino acid Ammonia Uric acid15. Which section of the Nephron is primarily responsible for concentrating the urine? Glomerulus Distal convoluted tubule Proximal Convoluted tubule Loop of Henle16. 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 cava17. The Urinary system consists of One bladder, two kidneys, one ureter, two urethras Two bladders, two kidneys, two ureters, one urethra Two bladders,two kidneys,one ureter, one urethra One bladder, two kidneys, two ureters, one urethra18. Choose the Odd one out Saliva Sweat Tears Urine19. The structural and functional unit of kidney is Urine Ureter Nephron Neuron20. Which product, secreted by the kidney, helps regulate blood pressure? Aldosterone Antidiuretic hormone Renin Cortisol21 out of Time is Up!
