51.

Collecting part of the tubule has:

A.	Permeability to water	B.	Impermeability to water
C.	Semipermeability to water	D.	None of these

52.

What causes liquid art of the blood to filter out from glomerulus into renal tubule?

A.	Osmosis	B.	Diffusion
C.	Dialysis	D.	High hydrostatic pressure

53.

In the condition of dilution of our extra-cellular fluid we have:

A.	More amount of diluted urine	B.	Less amount of diluted urine
C.	More amount of concentrated urine	D.	Normal urine

54.

We have more amount of diluted urine passed (polyurea) when our:

A.	ECF is diluted	B.	ECF is concentrated
C.	ECF is increased in ions	D.	ECF is normal

55.

Osmolality of our general ECF remains about:

A.	100ml osmol/litre of water	B.	200ml osmol/litre of water
C.	250 osmol/litre of water	D.	300 ml osmol/litre of water

56.

Diuresis is a condition when we excrete diluted urine, the osmolality of this urine is:

A.	50ml osmol/litre of water	B.	65ml osmol/litre of water
C.	75ml osmol/litre of water	D.	None of these

57.

Under the condition when our kidneys fail to dilute the urine the ECF remains diluted and this causes:

A.	Hypotension in our body	B.	Hypertension in our body
C.	More diuresis in our body	D.	No effect on our body

58.

Under the condition of renal hypertension the patient is to be administered with:

A.	Urea	B.	Glucose
C.	Manitol	D.	All of these

59.

When we take more tea we pass more urine because:

A.	Caffeine present in it is diuretic	B.	It increases concentration of our ECF
C.	It increases our blood pressure	D.	It depresses our nervous system

60.

Amount of urine in our body is regulated by:

A.	ADH from pituitary	B.	Aldosterone from adrenal glands
C.	Both of these hormones	D.	None of these hormones
