The seminiferous tubules are where the sperm cells are created. This is also the place where maturation and transportation of the sperm cells within the male testes.
They help you see.

The Bowman's Capsule is part of a Nephron, which would be found in the Kidney. It's function is to collect the filtrate from the Glomerulus, passing it on to the Proximal Convoluted Tubules (PCT's); subsequently, to the rest of the Nephron.
No, creatinine is not actively reabsorbed by the proximal convoluted tubule. Instead, it is freely filtered at the glomerulus and excreted in the urine. The amount of creatinine excreted is used to estimate kidney function.
His convoluted logic is hard to follow.

The distal convoluted tubule or the collecting tube.
somethings are too convoluted
"Convoluted" generally needs an additional verb: is, was, has been, will be - that is, in the passive voice (though the word can be used as an active verb as well. "The argument was convoluted." "His explanation is convoluted."
