Review of the Class:
- Male Reproductive System Quiz
- Recall of Oogenesis
-Talked about menstration
-Talked about Castor Semenya the track star who is a hermaphrodite
-Homework: pg 529 #4578
pg 527 a-k
Thoughts on the Material:
I enjoyed learning about this section. It is very interesting to know how the body does this whole thing to help humans procreate. We learned about menstration and how females get ready for pregnancy. Its fascinating what your body does and you dont even realize it. I was very interested in learning about Castor Semenya. She is a hermaphrodite. Her ovaries are actually testes. So she has never menstrated. How could that happen? What causes this to happen? Did she still keep her medals as a track star?
Above and Beyond:
Although i enjoyed the class today i was still very interested to know how Castor Semenya became a hermaphrodite. I still am not sure how that would happen. I used this website
http://rodonline.typepad.com/rodonline/2009/09/report-caster-semenya-intersex-internal-testes-and-no-ovaries.html this website talked about the fact that she had testes, and she also had no ovaries and no womb. i used this website
http://reproductivesystem.suite101.com/article.cfm/what_is_a_hermaphrodite to find out what a hermpharoite is. I hermaphrodite is some one with bothe male and female parts. this can occur from high levels of male hormones with a female fetus within the womb.

Rewiew of Class
Thoughts About Material
This new unit seems like it will be fairly easy. I hope there isn't anything too complex but it should be pretty straght forward. It is going to be really interesting learning about all the different parts of the human body. Human anatomy is going to be sweet. It is also going to be different to learn about all my own body parts because you can't see some of them. It's weird that some animals have such short reproductive cycles and I look forward to finding out why.
Above and Beyond
Some other species take alot longer than humans to reproduce, such as elephants. Once an elephant becomes pregnant she carries the calf for 21-23 months. This is an advantage because the fetus has more time to develope and thus be stroger and not as fragile once it's born. Elephants also have some of the same characteristics as humans like going through menapause and reaching sexual maturity. There is more interesting info if you go to the following link.

- Start New Unit: Human Reproductive System
- Handout on male reproductive system
- Talked about invetro pregnacy
- Other animal reproductive cycles

Micaiah Achtymichuk’s 2nd blog: Wednesday- March 10th, 2010. 3/3
What we did today...
(Block 1)
· We did the multiple choice and numerical response for the unit test on the Endocrine system.
· After completing MC we worked on any uncompleted work/ tickets to the test/ male reproductive system worksheets.
(Block 2)
· We completed the written response/short answer component for the Endocrine system.
· After completing we worked on any uncompleted work/ tickets to the test (Mr. Blankies, HOTFF Charts...) and male reproductive system worksheets.
· AND that is Wednesday biology double block in a nut shell folks.
Thoughts about the material:
· After discussing the amount of sperm produced by a human male daily and amount contained in the average ejaculation, it wonder how a verial male and female could fail to achieve pregnancy...
Above and beyond (Meta- cognition):
Both women and men have hormonal cycles which determine both when a woman can achieve pregnancy and when a man is most virile. The female cycle is approximately twenty-eight days long, but the male cycle is variable. Men can ejaculate and produce sperm at any time of the month, but their sperm quality dips occasionally, which scientists guess is in relation to their internal cycle.
Furthermore, age also plays a role, especially for women.
Although women can become pregnant at any time during their menstrual cycle, peak fertility occurs during just a few days of the cycle: usually two days before and two days after the ovulation date. This fertile window, varies from woman to woman, just as the ovulation date often varies from cycle to cycle for the same woman. The ovule is usually capable of being fertilized for up to 48 hours after it is released from the ovary. Sperm survive inside the uterus between 48 to 72 hours on average, with the maximum being 120 hours (5 days).
These periods and intervals are important factors for couples using the rhythm method of contraception.
So at this answers at least part of the equation...
I got my information here: (http://en.wikipedia.org/wiki/Fertility#Human_fertility) and i found a video about the subject here... (http://www.discoverychannel.ca/Showpage.aspx?sid=16698)

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!

Review of class
We looked the other day at how things can go wrong with your endocrine system. If there is too much of one hormone produced or too little. I was wondering how often it occurred that people had too much or too little of a certain hormone, specifically TSH because we`ve been looking at goiters and other symptoms associated with an under or over active thyroid.
Above and Beyond
I found on http://hcd2.bupa.co.uk/fact_sheets/html/underactive_thyroid.html that about 19 in every 1,000 women and 1 in 1,000 men in the UK, will develop hypothyroidism at some point in their lives and on http://hcd2.bupa.co.uk/fact_sheets/html/overactive_thyroid.html i found out that about one in 500 men and one in 50 women in the UK, will develop hyperthyroidism at some point in their lives. Hyperthyroidism seems to be more common to happen than hypothyroidism, but neither seem to be too common excpet for hyperthyroidism in women.
- Quiz 1 on the endocrine system
- Marked quiz
- Unit exam on endocrine system Wed. March 10
- Looked at more ES diploma style questions
- Went over notes sheet about hormones that affect water and ion balance
- Received another handout about our body`s reaction to stress

Reveiw of Class
- went over N.S unit exam numeric response and short answer
Recap:
- low blood sugar and insulin HOTFF
-Cortisol HOTFF
-Hormones associated with adrenal medulla
Started Hormones affecting metabolism- 15.3
We finished class with time to work on test tickets.
Thoughts on Material:
I found myself questioning how thyroid hormones regulate metabolism and found that this was not covered, just that they did. Also knowing someone whose had a goiter I was wondering what was the actuall swelling. Is it a build up of hormones or is it the gland itself? Dealing with the recap in class and insulin, i think trying to regulate yourself with needles if you have diabetes would be very hard. In todays worl I'm surrprised that there isnt a better solution (other than the pump) like a transplant.
Above and Beyond:
I checked out www.wikipedia.org/wiki/Thyroid_hormone#Function to find the function of thyroxing but I was unable to find a good source on how thyroid hormones work but i did learn that T3 is 3-4 times more potent than T4.
As far as the goiter I found some great stuff at www.bing.com/health/article/mayo-117220/Goiter?q=goiter. The main cause is Iodine defficiency and the thyroid grows in order to increase surface area to get more iodine. Eating food like cabbage and broccoli can also worsen this problem. Goiters caused by diseases seem to be brought on by simple swelling from overstimulation.
The idea of a pancrease transplant faces problems like rejection, infection, and are not recomended (along with beta cell implants) unless the patient is also having kindney transplant. The kidney transplant is a common and simple operation for diabetics facing complication associated with their disease. While at it, it is relatively easy and un-invasive to perform the pancrease implant although it is seldom performed. There is also the ability to transplant a partial pancrease from a living donor. www.faqs.org/faqs/diabetes/faq/part3/section-14.html

Carrie, Blog #1. Tuesday, March 2/10. Mark 3/3
What we did today...
1. Pop quiz
2. Finished the hormones related to metabolism
3. Worksheet on hormones realted to water balance
REMINDER..
Quiz tomorrow on blood sugar and metabolism hormones and our Unit exam is next wednesday.
Thoughts About The Material...
I never realized just how many homrones there were invovlved in our body. What I never knew was that you could produce a growth hormone out of bacteria by inserting human genes. I thought that the only way you could get hormones was chemically, like insulin injections, and naturally. I didn't think you could make grow then using bacteria out of common things such as banana's, I was just wondering if they had some major side effects, like if they caused pospubescent hyperproduction?
Above and Beyond
I followed this link http://en.wikipedia.org/wiki/Growth_hormone#Side-effects and found out that rhGH can cause an increase in the risk of diabetes, if used for training it can cause growth at a younger age, increase in colon and prostate cancer as well as joint swelling joint pain, carpal tunnel and less sleep.
