Which of the following statement is correct regarding urine formation?
1 Filtration and reabsorption takes place before secretion.
2 Filtration and secretion takes place before reabsorption.
3 Secretion takes place before reabsorption and filtration.
4 Reabsorption takes place before filtration and secretion.
Explanation:
(a) Urine formation is the result of ultrafiltration or glomerular filtration of the blood plasma by the glomeruli, selective reabsorption by the tubules and secretion by the tubules. Glomerular filtration is the first of the three processes that forms urine. Tubular reabsorption is the second process in the formation of urine from filtrate and tubular secretion is the third process in the urine formation.

Glomerular filtration rate (GFR) in a healthy individual is approximately
1 $100\text{ml}/\text{minute}$, i.e., 180 liters per day.
2 $125\text{ml}/\text{minute}$, i.e., 180 litres per day.
3 $120\text{ml}/$ minute, i.e., 100 litres per day:
4 $130\text{ml}/\text{minute}$ i.e., 120 litres per day.
Explanation:
(b) The amount of the filtrate formed by the kidneys per minute is called glomerular filtration rate (GFR). GFR in a healthy individual is approximately $125\text{ml}/$ minute, i.e., 180 litres per day.

1 $\text{NaCl}$ can pass by active transport from filtrate to the interstitial fluid.
2 $\text{NaCl}$ can pass by passive transport into interstitial fluid.
3 $\text{NaCl}$ cannot pass from the filtrate to interstitial fluid.

The urine under normal conditions does not contain glucose because
1 the normal blood sugar is fructose.
2 glucose of blood is not filtered in the glomerulus.
3 glucose in glomerular filtrate is reabsorbed in the uriniferous tubules.
4 glucose in glomerular filtrate is converted into glycogen.
Explanation:
(c) Under normal conditions, urine does not contain glucose because glucose in glomerular filtrate is reabsorbed in the uriniferous tubules.
