Sweat formed in the sweat glands passes into the sweat duct which opens to the outside at the surface of the skin by means of Sweat pore. What is alternating current and direct current? It transports urine from kidneys to urinary bladder. Ureter 12. So lungs act as excretory organs. Renal vein. The final changes in the composition and the volume of the nephric filtrate occurs in the loop of Henle and the distal convoluted loop of the tubule. Collecting tubule. The blood vessels which brings pure blood to the kidneys: 9. Collection of blood from the kidneys, (deoxygenated blood). Urea, uric acid 5. Question 5: The diagram below represents a mammalian kidney tubule (nephron) and its blood supply. Answer: Constituents of Urine: The normal human urine consists of about 95% of water and 5% of solid wastes dissolved in it. It is the production of chemical substances and pour them into the blood outside the body. Answer: Blood is alkaline in nature but urine formed from blood is acidic.

Ultrafiltration occurs in : (a) Bowman’s capsule (b) Proximal convoluted tubule (c) Henle’s loop (d) Distal convoluted tubule, 6. (False, Ammonia is converted into urea in liver.) (iii) Renal venuole. 4. 12. The liquid part of the blood filters through the walls of glomerular capillaries and Bowman’s capsule and enters into the nephron where it is called the glomerular filterate. Answer: (i) Excretory system, circulatory system, Endocrine system. Complete the following sentences with appropriate words : 1. Question 5: Describe about physical properties of urine. What is the Relationship between Electric Current and Potential Difference? Man also excretes urea, so he is called ureotelic and this phenomenon is termed as ureotelism. (Vasa recta Uterus) 6. In this way the kidneys eliminate only the wastes and extra substances from the body. Ammonia is converted into urea in kidney. Parts indicated by the guidelines 1 to 8 are as follows: 1. 10. (6) Urinary bladder—Store urine (7) Sphincter muscle—Control the voiding of urine (8) Urethra—Urine released periodically. (iii) Nephron or kidney tubules. Question 2: Why excretion is necessary ? So more blood is entering and less blood is moving out of the glomerulus. Question 2: Draw a well-labeled diagram of the human excretory system. These, if accumulate in the body, become poisonous and destroy the vital organs. If false rewrite the wrong statement in its correct form: 1. Delhi NTSE 2020 – 2021 | Exam Date, Application Form, Jammu & Kashmir NTSE 2020 – 2021 | Application Form (Released), Exam Date, Andhra Pradesh NTSE 2020 – 2021 | Exam Date, Application Form, Telangana NTSE 2020 – 2021 for Class X – Notification | Application Form Last Date (Extended), TGCET Application Form 2020 (Released!) It brings oxygenated blood into the kidney. (iii) Adrenal gland—At the top of kidney. Answer: Kidney plays a major role in the formation of urine. (iv) 7. Question 15: Explain the functioning of kidney. The nephrons have a tubular structure consisting of proximal and distal tubules which reabsorbs all the useful products present in the glomerular filtrate, and the process is called Tubular reabsorption. What are some common excretory product ? Question 6: Write constituents of urine. (ADH) 3. Answer: Question 1: The given diagram represents a nephron and its blood supply. Carry the proper stationery to attempt the question well and to avoid any chaos at the time of examination. This is called selective reabsorption. Glomerulus 13. Name three substances that are reabsorbed from the renal tubules by the secondary capillaries. Answer: Question 5: Excretion and Egestion. Certain substances like potassium (K) in the normal course, and a large number of foreign chemicals including drugs like penicillin are passed into the forming urine in tubular wall, and hence it is called tubular secretion. 12. The Bowman’s capsule 2. (iii) Name the endocrine gland which could be added in diagram and state its location/position. It is a part of the nephron consisting of glomerulus and the Bowman’s capsule. The organ in which urine is stored before its elimination. (True) 8. (v) (a) Ultrafiltration, (b) Selective reabsorption. Urochrome, bilirubin and biliverdin 9. (ii) Name the parts labeled 1, 2,3 and 4. Excretion of waste materials from the body. Sometimes urine may contain certain excess vitamins. (iv) Mention two functions of the kidney. Glomerulus 6. The content has been collected by me through various textbooks and classroom lectures taken by my Biology teacher, Mrs. S**** M*****. Renal pelvis, Medullary pyramid, Renal cortex, Renal papilla. Question 9: How does hydrostatic pressure develop in the glomerulus ? The waste product which is excreted by the liver. Avoid erasing the diagram again and again. The formation of urine takes place in two steps: (a) Ultrafiltration: The blood flows through the glomerulus under great pressure. (ii) Hypertonic. Question 4: Why is urine yellow in colour ? Hilus 6. Bowman’s capsule 4. A process by which the unwanted nitrogenous wastes are eliminated from the body. Proximal convoluted tubule, Distal convoluted tubule, Henle’s loop, Renal corpuscle. Question 3: It is necessary to maintain a normal osmotic concentration of blood ? 13. The duct which transports urine from the kidney to the urinary bladder. Question 1: Draw a labeled diagram of the human kidney as seen in a longitudinal section. When both the kidneys become fail to work the dialysis machine is used out. 14. Renal corpuscle 7. Venule to renal vein 7. What is the chief nitrogenous waste in mammals ? Answer: Explain the Terms. Class Notes for Class 9 to 12 … Question 10: Write about the excretory role of the lungs. Supply of blood to the kidneys, (oxygenated blood). The term used for Bowman’s capsule and glomerulus together. Carbon dioxide 17. Why ? (b) It helps in osmoregulation. This high pressure causes the liquid part of the blood to filter out from the glomerulus into the renal tubule (ultrafiltration). Glucose, Question: The organ which filters out urea and uric acid from the blood stream. Ureter 5. Excretion by eliminating extra water and salts. Nutrition in Amoeba: The students have to show how food is digested by Amobea – an unicellular organism. 2.

March 04, 2020. Question: 1. Liver, Angiotensin, Kidney, ADH. U-shaped loop of Henle 2. The organ in man concerned with maintaining water balance in the body. Column ‘II’ is a list of items related to ideas in Column ‘I’. 16. Answer the following questions: (i) Give the definition of excretion. in the glomerular filtrate is reabsorbed in the proximal part of renal tubule. (b) Reabsorption: The glomerular filtrate entering the renal tubule is an extremely dilute solution containing a lot of usable materials including glucose and some salts such as those of sodium. 17. Glomerulus: A single afferent arteriole of the renal artery breaks up into a number of capillary branches to form the glomerulus. The fluid which flows through the last part of the tubule is urine. (Uterus), 1. (b) B carries more O2 and nitrogenous waste product as it is Renal Artery. The branch of renal artery which enters into Bowman’s capsule. Comment. Tubular reabsorption Answer: 1. The patient’s blood is led from the radial artery in his arm through the machine where the urea and excess salts are removed and the purified blood is returned to a vein in same arm. Kidney 4. (4) Bowman capsule. (v) Where is the most water reabsorbed ? Answer: Diagram of human excretory system. Question 8: There is frequent urination in winter than in summer. It carries deoxygenated blood away from the kidney. (d) Odour: On standing, the smell of urine becomes strong, ammonia-like due to bacterial activity otherwise faint smell.
