Page 90 # 1-4, 5 on Hormone sheet

1.    Male changes at puberty include:  sperm production beginning, voice deepening, production of facial, underarm, pubic hair, and broadening of shoulders.

Female changes at puberty include:  ovaries begin to produce/release eggs, deposits of fat in breasts and hips, growth of pubic and underarm hair.

2.   Testosterone causes the appearance of secondary sexual characteristics in males, while estrogen causes the appearance of secondary sexual characteristics in females.  In BOTH sexes, FSH (follicle stimulating hormone) is produced at puberty to trigger (start) the development of the gonads( ovaries and testes).

3.   Start in the seminiferous tubules of the testis, move into the epididymis for maturation and storage, travel from there through the vas deferens, and continue along the urethra until they leave the body through the penis.  There are a few glands along the way like the prostate gland, Cowper’s gland and seminal vesicles that contribute fluids and lubricants to make the semen fluid enough to flow! 

 4.   The liquid mixture formed when sperm combined with the fluids secreted from the three glands labeled above is called semen.  The fluid gives the sperm something to swim in and nutrients for energy to make the trip to find an egg to fertilize.

Circulatory Slam 2011

Here are your instructions 8-7!

1)  Make sure your HEART DIAGRAM is filled out with the appropriate vocabulary by using the answer key from class here.

1.5)   Did you answer the questions on the back of the heart diagram????  The questions are here....check with Mrs. Snyder if you got them right or not!

2)  Fill out your JOURNEY of a RED BLOOD CELL bubble sheet (handed out Friday, Nov. 25th).
