it gives rise to the ureters, pelvises, calyces, collecting ducts, fully canalized by tenth week.
what does the metanephric mesenchyme give rise to
it is where the uteric bud interacts with the tissue and the interaction induces differentiation and formation of glomerulus through to distal convaluted tubeless.

wahat is the function of estrogen
development of genitalia and breast, female fate distraction. it encourages growth of the follicles, endometrial proliferation, and increased myometrial excitability. upregualton of estrogen, LH and progesterone receptors and feedback inhibition of FSh and stimulation of the LH urger.
