This jingle celebrates the unique role of the urethra in animal physiology. As expressed in the lyrics below, the urethra is part of two otherwise separate systems: the urinary system, and the male reproductive systems.
To get rid of pollution, and for sperm distribution,
There's a common solution -- hey, Urethra!
When the sperm are a-squirmin', or the toxins are burnin',
Send out semen or urine -- hey, Urethra!
Rete testis, efferent ductules,
Epididymis, vas deferens, ejaculatory duct.
Glomeruli to nephrons
To papillae to the calyces,
Renal pelvis, ureter, and bladder. Don't get stuck!
• MP3 (demo)
• sheet music (with melody play-back)
Songs like this one can be used during class meetings and/or in homework assignments. Either way, the song will be most impactful if students DO something with it, as opposed to just listening.
An initial, simple follow-up activity could be to answer the study questions below. A more extensive interaction with the song might entail (A) learning to sing it, using an audio file and/or sheet music as a guide, and/or (B) designing kinesthetic movements ("dance moves") to embody it. The latter activity could begin with students identifying the most important or most challenging content of the song, and deciding how to illustrate that particular content.
(1) Which series of steps represents the path of sperm, and which series of steps represents the path of urine?
(2) Between sperm and urine, which enters the urethra "first," i.e., at the most "upstream" location?
