Front 13

3 successive sets of kidneys develop in the human embryos:

Back 13

1st set of kidneys
2nd set of kidneys
3rd set of kidneys

Hint 13

Pronephroi
Mesonephroi
Metanephroi

Front 14

The nonfunctional, rudimentary pronephroi develop early in week =

Back 14

4

Pronephroi degenerate, leaving behind the pronephric ducts which run to the

Hint 14

cloaca

These ducts will remain and are utilized by other kidneys.

Front 15

The mesonephroi develop later during week =

Front 18

The mesonephroi degenerate toward the end of the

Back 18

first trimester.

However, their tubules become the

Hint 18

efferent ductules of the testes
and
the mesonephric ducts have several adult derivatives in the male.

Front 19

_________ are the primordia of permanent kidneys =

Back 19

Metanephroi

functional metanephroi or permanent kidneys develop early in week

They are functional by week =

Front 20

This excretion continues during fetal life and the fetus swallows this urine mixed in the amniotic fluid

Back 20

It is then absorbed in the stomach and duodenum and transport to the placenta for disposal.

Front 21

The permanent kidneys develop from two sources:

Back 21

(ureteric bud)
(metanephric blastema)

metanephric diverticulum
(ureteric bud)

metanephric mass of intermediate mesoderm
(metanephric blastema)

Front 22

Both primordia of the metanephros are of *________ origin.
