Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Profuse sweating takes place during heavy muscular exercise. The reason is To regulate the temperature of the body All of these To eliminate excessive lactic acid produced due to anaerobic metabolism To excrete excess amount of sodium chloride2. Which of the following organs is the storage area of urine? Urethra Ureter Kidney Urinary bladder3. The removal of nitrogenous wastes is called as Sweating Defecation Excretion Breathing4. What is the chief nitrogenous waste in mammals? Urea Uric acid Ammonia Amino acid5. What is located within the glomerular capsule? Renal cortex A knot of capillaries Loop of Henle Several conducting ducts6. Ultrafiltration occurs in Henle's loop Distal convoluted tubule Bowman's capsule Proximal convoluted tubule7. Maximum amount of water from glomerular filtrate is reabsorbed in Proximal convoluted tubule Distal convoluted tubule Ascending limb of loop of Henle Descending limb of loop of Henle8. The apex of each pyramid which projects into the pelvis of the kidney is called Medulla Papilla Calyx Pyramid9. A tube that arises from the kidney and connects behind with the urinary bladder is called Renal tubule Pelvis Urethra Ureter10. Which of the following are located in the cortex of the kidney? Glomerulus and Proximal tubule Loop of Henle Ascending limb, descending limb and collecting duct Glomerulus, PCT and DCT11. Which section of the Nephron is primarily responsible for concentrating the urine? Loop of Henle Proximal Convoluted tubule Distal convoluted tubule Glomerulus12. The structural and functional unit of kidney is Ureter Nephron Neuron Urine13. 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 urethra14. Which product, secreted by the kidney, helps regulate blood pressure? Renin Aldosterone Antidiuretic hormone Cortisol15. Excretion primarily involves Removal of all by-products during catabolism Removal of nitrogenous waste All of the above Removal of by-products during anabolism16. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Appendix Sphincter Villus Cecum17. Choose the Odd one out Saliva Tears Urine Sweat18. The consumption of alcohol has what effect on the human urinary system? 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 production It decreases the activity of antidiuretic hormone(ADH), increasing urine production19. Where does blood go after it leaves the glomerulus? It runs parallel to the nephron via the efferent arterioles It re-enters pulmonary circulation It returns to the heart via the inferior vena cava It runs parallel to the nephron via the efferent venules20. The bowman's capsule and the glomerulus together are called Renal capsule Malpighian capsule or Renal capsule Renal tubule Malpighian capsule21 out of Time is Up!
