Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Which of the following organs is the storage area of urine? Ureter Kidney Urethra Urinary bladder2. Excretion primarily involves Removal of nitrogenous waste Removal of all by-products during catabolism All of the above Removal of by-products during anabolism3. The removal of nitrogenous wastes is called as Breathing Defecation Sweating Excretion4. The consumption of alcohol has what effect on the human urinary system? It increases the activity of antidiuretic hormone(ADH), decreasing urine production It results in dark, concentrated urine It completely blocks the flow of fluids through the kidney tubules It decreases the activity of antidiuretic hormone(ADH), increasing urine production5. Choose the Odd one out Urine Saliva Tears Sweat6. Ultrafiltration occurs in Bowman's capsule Distal convoluted tubule Henle's loop Proximal convoluted tubule7. Where does blood go after it leaves the glomerulus? It re-enters pulmonary circulation It runs parallel to the nephron via the efferent arterioles It runs parallel to the nephron via the efferent venules It returns to the heart via the inferior vena cava8. Profuse sweating takes place during heavy muscular exercise. The reason is To regulate the temperature of the body To eliminate excessive lactic acid produced due to anaerobic metabolism All of these To excrete excess amount of sodium chloride9. Which section of the Nephron is primarily responsible for concentrating the urine? Glomerulus Distal convoluted tubule Proximal Convoluted tubule Loop of Henle10. A tube that arises from the kidney and connects behind with the urinary bladder is called Urethra Pelvis Ureter Renal tubule11. The structural and functional unit of kidney is Neuron Ureter Nephron Urine12. The apex of each pyramid which projects into the pelvis of the kidney is called Calyx Papilla Pyramid Medulla13. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Cecum Appendix Sphincter Villus14. Which of the following are located in the cortex of the kidney? Loop of Henle Glomerulus, PCT and DCT Glomerulus and Proximal tubule Ascending limb, descending limb and collecting duct15. Which product, secreted by the kidney, helps regulate blood pressure? Antidiuretic hormone Aldosterone Cortisol Renin16. What is located within the glomerular capsule? Loop of Henle Renal cortex Several conducting ducts A knot of capillaries17. The Urinary system consists of Two bladders,two kidneys,one ureter, one urethra One bladder, two kidneys, two ureters, one urethra Two bladders, two kidneys, two ureters, one urethra One bladder, two kidneys, one ureter, two urethras18. The bowman's capsule and the glomerulus together are called Renal tubule Malpighian capsule or Renal capsule Renal capsule Malpighian capsule19. 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 Henle20. What is the chief nitrogenous waste in mammals? Urea Uric acid Ammonia Amino acid21 out of Time is Up!
