Which one of the following correctly explains the function of a specific part of a human

nephron?

1. Henle's loop - most reabsorption of the major substances from the glomerular filtrated 

2. Distal convoluted tubule - reabsorption of ions into the surrounding blood capillaries

3. Afferent arteriole - carries the blood away from the glomerulus towards renal vein 

4. Podocytes- create minute spaces (slit pores) for the filtration of blood into the

Bowman's capsule

Which one of the following is not a part of a renal pyramid?

1. Convoluted tubules

2. Collecting ducts

3. Loops Henle

4. Peritubular capillaries

Uricotelic mode of passing out nitrogenous wastes is found in

1. birds and annelids

2. amphibians and reptiles

3. insects and amphibians 

4. reptiles and birds 

Which one of the following statements is correct with respect to kidney function

regulation?

1. Exposure to cold temperatures stimulates ADH release

2. An increase in glomerular blood flow stimulates the formation of angiotensin II

3. During summer when the body loses a lot of water by evaporation, the release of ADH is

suppressed

4. When someone drinks a lot of water ADH release is suppressed

Which one of the following statements in regard to excretion by the human kidneys is correct?

The principal nitrogenous excretory compound in humans is synthesised.

1. in kidneys but eliminated mostly through liver

2. in kidneys as well as eliminated by kidneys

3. in liver and also eliminated by the same through bile

4. in the liver, but eliminated mostly through kidneys

Uric acid is the chief nitrogenous component of the excretory products of 

1. man                             

2. earthworm

2. Less amino acids in his urine

3. More glucose in his blood

4. Less urea in his urine

Angiotensinogen is a protein produced and secreted by:

1. Macula densa cells

2. Endothelial cells (cells lining the blood vessels)

3. Liver cells

Figure shows human urinary system with structures labelled A to D. Select option,

which correctly identifies them and gives their characterstics and/of functions.

1. A-adrenal gland located at the anterior part of kidney. Secrete catecholamines,

which stiumate glycogen breakdown

2. B-pelvis broad funnel shaped space inner to hilum, directly connected to loops of

Henle

3. C-mediulla-inner zone of kidney and contains complete nephrons

4. D-cortex-outer part of kidney and do not contain any part of neohrons
