Which one of the following statements are correct ?
(i) Inside the kidney there are two zones, an outer cortex and an inner medulla.
(ii) The medulla of kidney is divided into a few conical masses called medullary pyramids projecting into calyx.
(iii) The medullary pyramids of kidney extends in between the cortex as renal columns called columns of bertini.
(iv) The functional unit of kidney is nephron. It has two parts glomerulus and renal tubule.
(v) Glomerulus along with Bowman's capsule is called malpighian body or renal corpuscle.
(vi) In juxta medullary nephron, loop of Henle is short and extends only very little into the medulla.
(vii) In cortical nephron, loop of Henle is long and runs deep into the medulla.
(viii) The efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule called the peritubular capillaries.
(ix) A large vessel of peritubular capillaries that runs parallel to Henle's loop forms "U" shaped vasa recta.
(x) Vasa recta is absent or highly reduced in juxta medullary nephrons.
(xi) The first step of urine formation is glomerular filtration.
