Pump-pump-pump-pump-pumps your blood!!

This is the video we watched to learn how blood travels through your heart.

LYRICS:

Pump, pump, pumps your blood.


 The right atriums where the process begins,

where the CO2 blood enters the heart.


Through the tricuspid valve, to the right ventricle, the pulmonary artery, and lungs.


Once inside the lungs, it dumps its carbon dioxide and picks up its oxygen supply.


Then its back to the heart through the pulmonary vein, through the atrium and left ventricle.


Pump, pump, pumps your blood.

Pump, pump, pumps your blood.


Verse 2:

The aortic valves, where the blood leaves the heart,

then it's channeled to the rest of the bod.


The arteries, arterioles, and capillaries too

bring the oxygenated blood to the cells.


The tissues and the cells trade off waste and CO2,

which is carried through the venules and the veins.


Through the larger vena cava to the atrium and lungs,

and we're back to where we started in the heart.


Pump, pump, pumps your blood.

Testing on Chimps...

This week in class we learned all about how chimpanzees, the animals most similar to humans, are being tested on for cures to assorted diseases.  A lot of these chimps are started off being raised to do other kinds of experimentation, such as learning sign language, or studied for their habits in behavior, emotions, and brain stimuli.  The sad part is though; many, many of these animals are then sent to a facility that infects them with Hepatitis C and HIV and uses them to try out cures for this disease given that they are the closest we can get to humans by similarity.  Not only is this method for coming up with a cure heartbreaking for these animals, but also seemingly is collecting incorrect data.  If they really wanted to test these possibly cures out, they would do it in a way where the chimps socialized with one another as well as being exposed to the outdoors.  People who are really sick with these viruses are not quarantined or kept in full seclusion from everything as these chimps are having to be, but they are out and getting exposed to other things as well that may change the virus.  So all in all, i think that animal testing in itself is horrible, and doing it on animals like Chimpanzees is even more horrible given that they have so much more to offer the world than being cooped up in a box poked and prodded with needles everyday.

Overall Web Designer and Community Connections

In class we're making 2 things. One, a cookbook- only composed of Anti-Angiogenisis recipes...
Two, a website.  This website focuses on the systems throughout the body, and my group is doing a page of this site about the Deigestive System.  Everyone in each group has a job that is critical to the website and overall project.  My job is pretty much to keep everyone on track and to make sure that our website is always closer and closer to being finished, as well looking more and more beautiful as the design improves.  The second part of my job is to find a way to connect the community with what we are doing, and interview, or somehow incorporate locals into our website project.  Once this page is being finished, I'll post a link to show it off!! :)

Heck no H2O!!! (just kidding..)

This week in class we read a very interesting article about the amount of water we intake, and if it sometimes may be too much.  Living in a dry climate, I'm used to feeling like i need to be drinking more than I am or do, but after reading this article it made me feel a little differently.  It said that if we drink too much, also known as water intoxication.  If too much water if put into your system at one point, the kidneys can't handle that kind of hydration. Multiple medical researchers advise to only put as much water into your system as you put out in sweat.  However, living in a dry climate, it's sometimes hard to see how much you sweat given it seems to evaporate off semi-quickly, so they also advise to drink your thirst.  By doing this, you don't deprive your body from water in any way, but at the same time you don't OVER hydrate... As an athletic person, I took this article to heart, and am now more conscious about my water intake.  Whether it be drinking more or less than I am used to, I feel like this article helped me be more self-conscious.

Organ Transplanting... Bias??

In class we had a long project on organ transplating, and whether or not our system is in need of changes.  After conducting sort of a play-organ-stransplant-debate, and hearing the variety of people in need of different organs is a very hot commodity it seems.  From teenagers that are left with one kidney becasue they donated one to a family member, to an elderly woman with eight grand kids, the choice is very hard for whoever has to make the tough decision of who gets what.  Speaking of which- who does get to make this decision? Who is the person that gets to decide who gets life, and who doesn't? What evidence do they base this decision off of? By doing this talk in class, it is now clear that unfortunately money and social rank do sometimes play a leading role in who gets organs sooner than others. For instance, between a young boy in Kansas who will soon die if not given a needed organ, and Oprah Winfrey who can live without it, but needs the same organ sooner than later, who do you think will get the selected organ?? Not hard to imagine... Another candidate to these organs is felons.  Although locked up, they are given the right to Health Care, just as any other person is.  Although these people will be locked up for most of if not the rest of their lives, they still get organs just as people who are out of jail do... what do you think of all of this??

Liiightinnngggg Striiikinggg Aaaagainnnn!!!

Last year my physics teacher was trying to find videos on YouTube about lighting, and when she typed in "Lightning Strikes" this is what we saw in class.... I'd say its MUCH better than watching lightning actually striking something. hahaha

Organ Transplant Debate... HOT TOPIC!!

Tomorrow in class, we are having a debate on whether or not felons should revieve organs, and who gets to decide this, and why- along with other topics of course... Once this discussion has taken place, ill post a new post, and tell about it!!

Blog Numero Uno

My name is Lily, and I am in 10th grade Biology, where we will study all sorts of things throughout the year, of which i will post pictures, essays, possibly videos, and links that are helpful to what we may be studying at that time. Eventually this blog will be filled to the brim with super cool information, so be sure to follow it if it at all interests you... :D
