[A] : The hormone aldosterone is secreted by adrenal cortex after the low `Na^+` content in blood and the resultant low BP causes the kidney to release renin.
[R]: Renin in blood leads to the formation of angiotensin II which causes adrenel cortex to release aldosterone that causes kidney to re- tain `Na^+` and, therefore, water is reabsorbed and BP rises.

Assertion :- Angiotensin II, activates the adrenall cortex to release aldosterone. Reason :- Aldosterone causes reabsorption of Na^(o+) and water from the distal parts of the tubule.

[A] : Cortisol is a protein hormone that regu- lates gluconeogenesis and lowers blood pressure. [R]: Low level of cortisol promotes release a factor from the aderanal cortex causing release of ACTH

Read the following statements (A - D) : 1. Catecholamines secreted from adrenal medulla stimulate breakdown of glycogen resulting in an increased concentration of glucose in blood. 2. Cortisol is also involved in maintaining the cardio -vascular syem as well as kidney functions. 3. Hormone released from zona fasciculate produce anti-inflammatroy reactions and suppresses the immune response. 4. Androgenic steroids secreted by adrenal cortex play a role in growth of axial hair, pubic hair and facial hair during puberty. How many of the above statements are ture?

Which of the following sequence is correct? (i) An increase in body fluid volume rarr switch off the osmoreceptors rarr suppresses the ADH Release (ii) ADH rarr Constricting effect on blood vessel rarr B.P. high rarr Glomerular blood flow more rarr GFR more (iii) Angiotensinogen rarr Angiotensin I rarr Angiotensin II rarr Adrenal cortex rarr Aldosterone (iv) Angiotensin rarr ADH rarr GFR more rarr Aldosterone rarr B.P. high

You and your study partner want of draw the pathway that controls the controls the reabsorption of sodium ion when blood pressure falls. Which of the following is the correct sequence of events ? (a) Aldosterone is released (b) Kidney tubules reabsorb Na^(+) (c ) Renine is released (d) Juxtaglomerular apparatus (JOA) recongnizes a drop in blood pressure. (e ) Angiotensin II is produced

The correct match is I. DCT - Secretion of H^(+) and K^(+) ions II. Henle's loop -Reabsorption of glucose, water and Na^(+) ions III. Podocytes - Attached to parietal layer of Bowman's capsule IV. JGA - Rise in glomerular blood pressure activates it to release renin.

Column I some disorders associated with brain. Column II the causes for these disorders. Match the two column and identify the correct option from those given: {:("Column-I","Column-II"),(A" Epilepsy", p" Degeneration of neurons in the cerebral cortex"),(B" Alzheimer's disease", q" Irregular electrical discharge in the neurons"),(C" Parkinson's disease", r" Decreased production of acetylcholine"),(D" Huntington's chorea", s" Regeneration of dopamine releasing neurons"),(,t" Formation of blood dots in the brain"):}

READ THE FOLLOWING PASSAGE CAREFULLY: 1. THERE ARE TWO TYPES OF DIABETES, INSULIN DEPENDENT, AND NON-INSULIN DEPENDENT. 90-95% OF THE ESTIMATED 13-14 MILLION PEOPLE IN THE UNITED STATES WITH DIABETES HAVE NON-INSULIN DEPENDENT, OR TYPE II DIABETES. BECAUSE THIS TYPE OF DIABETES USUALLY BEGINS IN ADULTS OVER THE AGE OF 40 AND IS MOST COMMON AFTER THE AGE OF 55, IT USED TO BE CALLED ADULT-ONSET DIABETES, ITS SYMPTOMS OFTEN DEVELOP GRADUALLY AND ARE HARD TO IDENTIFY AT FIRST, THEREFORE NEARLY HALF OF ALL THE PEOPLE WITH DIABETES DO NOT KNOW IT. SO, SOMEONE WHO HAS DEVELOPED TYPE II DIABETES MAY FEEL TIRED OR ILL WITHOUT KNOWING WHY. THIS CAN BE PARTICULARLY DANGEROUS BECAUSE UNTREATED DIABETES CAN CAUSE DAMAGE TO THE HEART, BLOOD VESSELS, EYES, KIDNEYS, AND NERVES. WHILE THE CAUSES, SHORT-TERM EFFECTS, AND TREATMENTS OF THE TWO TYPES OF DIABETES DIFFER, BOTH TYPES CAN CAUSE LONG-TERM HEALTH PROBLEMS. 2. MOST IMPORTANTLY, BOTH TYPES AFFECT THE BODY’S ABILITY TO USE DIGESTED FOOD FOR ENERGY. DIABETES DOES NOT INTERFERE WITH DIGESTION, BUT IT DOES PREVENT THE BODY FROM USING AN IMPORTANT PRODUCT OF DIGESTION, GLUCOSE, FOR ENERGY. AFTER A MEAL, THE NORMAL DIGESTIVE SYSTEM BREAKS SOME FOOD DOWN INTO GLUCOSE. THE BLOOD CARRIES THE GLUCOSE OR SUGAR THROUGHOUT THE BODY, CAUSING BLOOD GLUCOSE LEVELS TO RISE. IN RESPONSE TO THIS, INSULIN IS RELEASED INTO THE BLOODSTREAM AND SIGNALS THE BODY TISSUES TO METABOLIZE OR BURN THE GLUCOSE FOR FUEL, WHICH CAUSES BLOOD GLUCOSE LEVELS TO RETURN TO NORMAL. THE GLUCOSE THAT THE BODY DOES NOT USE IS STORED IN THE LIVER, MUSCLE OR FAT. 3. IN BOTH TYPES OF DIABETES, THE NORMAL FUNCTION OF GLANDS IS AFFECTED. A GLAND CALLED PANCREAS MAKES INSULIN. IN PEOPLE WITH INSULIN-DEPENDENT DIABETES, THE PANCREAS DOES NOT PRODUCE INSULIN AT ALL. PEOPLE WITH NON-INSULIN DEPENDENT DIABETES USUALLY PRODUCE SOME INSULIN IN THEIR PANCREAS, BUT THEIR BODY TISSUES DO NOT METABOLIZE THE GLUCOSE PROPERTY, A CONDITION KNOWN AS INSULIN RESISTANCE. 4. THERE’S NO CURE FOR DIABETES YET. HOWEVER, THERE ARE WAYS TO GET RELIEF FROM ITS SYMPTOMS. FOODS THAT ARE RICH IN CARBOHYDRATES BREAK DOWN INTO GLUCOSE DURING DIGESTION, CAUSING BLOOD GLUCOSE TO RISE. ALSO, STUDIES HAVE SHOWN THAT COOKED FOODS RAISE BLOOD GLUCOSE HIGHER THAN RAW, UNPEELED FOODS. SO WE SHOULD EAT SUCH UNCOOKED WHOLE GRAIN FOODS. ON THE BASIS OF YOUR READING OF THE ABOVE PASSAGE, MAKE NOTES ON IT USING HEADINGS AND SUB-HEADINGS. USE RECOGNIZABLE ABBREVIATIONS WHEREVER NECESSARY (MINIMUM FOUR).
