(a) Distal convoluted tubule (b) Proximal convoluted tubule (c) Nephron loop the most abundant organic waste in the urine is: (a) Creatinine (b) Uric acid (c) Urea (d) albumin Which segment of a nephron has the specific function to retain plasma proteins and blood cells? (a) PCT (b) Nephron loop (c) Renal corpuscle (d) Collecting duct Which hormone stimulate ion-pump Na+ reabsorption: (a) Antidiuretic hormone (b) Aldosterone (c) Follicle stimulating hormone (d) Gastrin Folds of the urinary bladder lining that disappear as the bladder fill is called: (a) Ureter (b) Trigone (c) Rugae (d) Urinary sphincter In Female, Extracellular fluid is more that intra cellular fluid.

Explanation / Answer
13) The pH is negative logarithm( component) of the hydrogen ion concentration [H+]..
Answer is : C
12) The primary route for ion and water loss from the body is kidney system...
Answer is : N
11) Sodium ions are the major cations found outside cells( extracellular) in the body. They regulate and control the level of body fluids...
Answer is B
10) Extracellular fluid is lost from the body more rapidly than intracellular fluid. So intracellular fluid is more. A woman has more body fat than a man, means the woman has less body fluid than the man : false
9) rugae are the folds in the mucosa of the bladder and they disappear as the bladder fills with urine.
Answer is C
8) Aldosterone is a hormone that stimulates Na+ and water reabsorption from the gut...
Answer is B
