Excretory System Class 10 Welcome to your Excretory System Class 10 Name 1. Choose the Odd one out Tears Sweat Urine Saliva2. What is located within the glomerular capsule? Renal cortex A knot of capillaries Several conducting ducts Loop of Henle3. Excretion primarily involves All of the above Removal of all by-products during catabolism Removal of by-products during anabolism Removal of nitrogenous waste4. Which term describes a one way valve composed of smooth muscle that functions in elimination of urine? Sphincter Villus Appendix Cecum5. A tube that arises from the kidney and connects behind with the urinary bladder is called Pelvis Ureter Urethra Renal tubule6. Which section of the Nephron is primarily responsible for concentrating the urine? Glomerulus Distal convoluted tubule Proximal Convoluted tubule Loop of Henle7. The structural and functional unit of kidney is Ureter Neuron Nephron Urine8. Where does blood go after it leaves the glomerulus? It runs parallel to the nephron via the efferent arterioles It runs parallel to the nephron via the efferent venules It re-enters pulmonary circulation It returns to the heart via the inferior vena cava9. Maximum amount of water from glomerular filtrate is reabsorbed in Descending limb of loop of Henle Ascending limb of loop of Henle Proximal convoluted tubule Distal convoluted tubule10. The removal of nitrogenous wastes is called as Defecation Breathing Excretion Sweating11. 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 urethras12. Which product, secreted by the kidney, helps regulate blood pressure? Aldosterone Renin Antidiuretic hormone Cortisol13. Which of the following organs is the storage area of urine? Ureter Kidney Urethra Urinary bladder14. Ultrafiltration occurs in Proximal convoluted tubule Bowman's capsule Henle's loop Distal convoluted tubule15. Profuse sweating takes place during heavy muscular exercise. The reason is To excrete excess amount of sodium chloride All of these To regulate the temperature of the body To eliminate excessive lactic acid produced due to anaerobic metabolism16. 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 production17. The apex of each pyramid which projects into the pelvis of the kidney is called Calyx Papilla Pyramid Medulla18. The bowman's capsule and the glomerulus together are called Renal capsule Malpighian capsule or Renal capsule Malpighian capsule Renal tubule19. Which of the following are located in the cortex of the kidney? Glomerulus, PCT and DCT Loop of Henle Ascending limb, descending limb and collecting duct Glomerulus and Proximal tubule20. What is the chief nitrogenous waste in mammals? Amino acid Ammonia Uric acid Urea21 out of Time is Up!
