Thursday, March 12th, 2009, Rachel Schneider, Blog #1 - (3/3)

What we did today:

• Talked about the Endocrine System Unit Exam results - 58% class average on written response, 60% class average on multiple choice


• Started Reproduction System by looking over questions on page 508 #1ab, 4, 5ac and page 510 #1, 3a


• Recieved fill-in-the-blanks notes on the male reproductive system, which we went through in class. Questions on page 519 #1 & 4 assigned (due tomorrow - March 13th) and a worksheet (due Tuesday, March 17th)
  

Thoughts and Opinions:

It's kind of crazy how much a sperm a guy produces in relation to how many eggs a girl produces. In his lifetime, a guy will produce around a trillion sperm compared to a girl's 400 000 eggs in her lifetime, of which only around 400 will be ovulated. Jeez, take a rest guys.

Above and Beyond:

Did you know that a sperm can live for 7 days inside a lady's special place?
Check it out here.
According to that site, not only will around 749 999 999 sperm feel ashamed for not being the one to fertilize the egg, but they'll have to swim around for about 7 days with nothing left to do but die.
Poor little sperm.
