Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Which product, secreted by the kidney, helps regulate blood pressure? Cortisol Renin Aldosterone Antidiuretic hormone2. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Villus Cecum Appendix Sphincter3. The removal of nitrogenous wastes is called as Defecation Sweating Breathing Excretion4. The consumption of alcohol has what effect on the human urinary system? It decreases the activity of antidiuretic hormone(ADH), increasing urine production It results in dark, concentrated urine It completely blocks the flow of fluids through the kidney tubules It increases the activity of antidiuretic hormone(ADH), decreasing urine production5. What is the chief nitrogenous waste in mammals? Amino acid Urea Ammonia Uric acid6. Which of the following organs is the storage area of urine? Kidney Ureter Urethra Urinary bladder7. Where does blood go after it leaves the glomerulus? It runs parallel to the nephron via the efferent arterioles It returns to the heart via the inferior vena cava It re-enters pulmonary circulation It runs parallel to the nephron via the efferent venules8. The bowman's capsule and the glomerulus together are called Renal tubule Malpighian capsule or Renal capsule Malpighian capsule Renal capsule9. The structural and functional unit of kidney is Neuron Nephron Ureter Urine10. Profuse sweating takes place during heavy muscular exercise. The reason is All of these To eliminate excessive lactic acid produced due to anaerobic metabolism To excrete excess amount of sodium chloride To regulate the temperature of the body11. Which of the following are located in the cortex of the kidney? Loop of Henle Glomerulus, PCT and DCT Ascending limb, descending limb and collecting duct Glomerulus and Proximal tubule12. Ultrafiltration occurs in Henle's loop Proximal convoluted tubule Distal convoluted tubule Bowman's capsule13. 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 Henle14. Choose the Odd one out Saliva Urine Sweat Tears15. Excretion primarily involves Removal of nitrogenous waste All of the above Removal of all by-products during catabolism Removal of by-products during anabolism16. The apex of each pyramid which projects into the pelvis of the kidney is called Medulla Calyx Papilla Pyramid17. 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. What is located within the glomerular capsule? Loop of Henle Renal cortex A knot of capillaries Several conducting ducts19. A tube that arises from the kidney and connects behind with the urinary bladder is called Ureter Urethra Pelvis Renal tubule20. Which section of the Nephron is primarily responsible for concentrating the urine? Proximal Convoluted tubule Loop of Henle Distal convoluted tubule Glomerulus21 out of Time is Up!
