Jeff Smith for the class of Tuesday, march 9th. 2nd blog 3/3

Review of class:
-began with formative quiz on second half of the endocrine system
-marked and reviewed answers for tomorrow's Unit final
-began new notes on the reproduction and development unit. specifically the male reproductive system
-were given ticket to test for male reproductive system.

Thoughts on the material:
The material in class today is very interesting. I find myself becoming intrigued with the information we're covering so far in this unit. As we learn more about our bodies and what makes them tick i find myself becoming more diligent in doing homework and getting to know my material!-who knew. One fact that i found particularly interesting was that there are so many obstacles and counteractions by the male body on the way to becoming pregnant. The environment inside the female body is very acidic..perhaps it shows through to their attitude at times? and the male body must secrete fluids from the prostate gland and cowper's gland to neutralize the acidity of the female body and provide a plausible way to get to the egg in the female reproductive system.

Above and Beyond:
With all the new information in this day of classes, it seems that a poor little sperm has little chance of actually making it all the way to the egg and being the one who actually gets the fertilizing done. Mathematically, if 500000000 sperm cells are delivered in an ejaculation, the probability of any given single cell to be the one who actually fertilizes the egg is2.0x10-9! very small percentage chance!
