A patient exhibits excessive thirst and urination, producing large volumes of dilute urine. Blood tests reveal normal glucose levels. Which of the following is the MOST likely hormonal imbalance causing this condition?
Increased Aldosterone
Decreased Antidiuretic Hormone (ADH)
Increased Atrial Natriuretic Peptide (ANP)
Decreased Renin

The process of removing unwanted substances from the blood into the filtrate is called:
Glomerular filtration
Tubular reabsorption
Tubular secretion
Osmosis
Choose the correct ones
I. Afferent arteriole carries the blood away from the glomerulus toward renal vein
II. Efferent arteriole carries the blood to glomerulus
III. Podocytes form minute spaces (slit pores) for the filtration of blood into the Bowman’s capsule
IV. In Henle’s loop There are most reabsorption of the major substances from the glomerular filtrate
V. Distal convoluted tubule reabsorption K^+ ions into the surrounding blood capillaries
The correct option is
I and II only
III only
III, IV, and V only
I, II, and IV only
In which part of the nephron does the majority of water reabsorption occur, and under what primary hormonal influence?
Distal convoluted tubule; influenced by ADH
Collecting duct; influenced by ADH
Loop of Henle; influenced by aldosterone
Proximal convoluted tubule; influenced indirectly by aldosterone

Isotonic urine
Hypertonic urine
Hypotonic urine
Acidic urine
Choose the correct ones: I. Vasa recta is lacking in cortical nephrons, II. Maximum number of nephrons in kidney are juxta-medullary type, III. DCT of many nephorns open into collecting tubule, IV. During summer when body loses lot of water by evaporation, the release of ADH is suppressed, V. When someone drinks lot of water, ADH release is suppressed, VI. Exposure to cold temperature stimulates ADH release, VII. An increase in glomerular blood flow stimulates formation of angiotensin II. The correct option is
All except I and IV
All except V and VII
All except I and V
All except II and VI
