  1. Renal artery, afferent arterioles, glomerulus, efferent arterioles, secondary capillaries, renal vein.

 

  1. Sphygmomanometer is the instrument which measures blood pressure.

 

  1. Lymph contains much less proteins than plasma because the capillary wall is impermeable to plasma proteins.
