THE PIG DISECTION!!!!

SUMMARY
On Jaunuary 15 we disected a pig fetus. WE learned about the organs and got a Hands On experience on what the organs looked and felt like. We then had to do a work sheet on what the function of the organs were in the pig.

THOUGHTS AND OPINOINS
I thought that this was probably the highlight of the year for me. The pig disection was just so much fun and i also learned allot about how the body worked. But i thought we should have done the disection on a double block so we could have had a bit more time looking through the pig and looking at the organs. I cut off the head and that was pretty sweet!

i put thisn one here so you could try out the pig disection if you might have missed it because its so sweet. but it wont be as fun as the real thing.

Summary

Today in class, Mr. C. had all the kids paired in groups of 2 or 3 and had us prepare a lab that demonstrated the production of heat during excersize. So we had to:

-make a hypothesis ( if, then, because statement)

- design a procedure that would increase our body temperature

- Point out our variables (Manipulated, Controlled and Responding)

- tell how or why our body temp. increased

- Lastly, to make a conclusion, graph and table that illustrated our results within a group.

Thoughts and Opinions

Well Mr. C. I thought it was fun. My idea was to hop on one foot down the hall but the other ones didnt really want to.... Anyways. It was a fun activity to do and let us know why our body heat increased during activity.Some of the students just walked around the school for a while, and others actually took initiative and did something that was physically active. One of the students hopped around the class room for a bit, which was funny to watch.

To say the least, it was fun, worth-while, and educational.

Above and Beyond

Haha.. Anyways.

My additional insight is going to be a picture of the Gross anatomy.

Class Summary
- Began the muscle / motor system unit-
Three Main types of muscle tissue
- Cardiac: found in heart, involuntary (autonomic)
- Skeletal: moves bones, voluntary
- Smooth: found in organs, veins, arteries etc, involuntary
- Started looking more in depth with skeletal system
- Antagonistic pairs
- Muscle contraction (actin and miocin)

Thoughts on the Lesson

I thought the lesson gave a reasonable introduction to the motor system. For once I actually kinda understood what was going on during the first day. I dislike that we were assigned things with 10 minutes to go, but whatever. At least I could answer the questions. I think that the function of the muscle system is a little more obvious, and there will be less to do. I think that we will have to do some more work with muscle contractions before I understand the miocin / actin thing.

Above and Beyond

During this lesson I started to think of how going to the gym builds muscle strength. I didn’t really know how muscle fibre was produced or whatever makes you stronger. Mostly I was daydreaming and wondering what to put for above and beyond in my blog. Before finding this website I would have never guessed that this is how muscle growth occurred. So here it is:

Muscle fibre growth

Your muscles are made up of thousands of fibres called 'myofibres'. Lifting weights causes microscopic tears in the muscle fibres. Training actually breaks down the muscle.
Your body rebuilds the damaged fibres making them bigger and stronger. It does this to adapt to the stress of training. The next time you go to the gym, you'll be bigger and stronger. Your body can cope better, and so, less stress.
Many believe that muscle growth happens when they train. It is only between workouts, when we rest and feed the muscles that growth occurs.
How to increase muscle size.
We must train hard enough to damage the muscle fibres so our body rebuilds them bigger and stronger.

Today in class we:

• Answered questions:

1) Which molecules carry energy from light reactions to dark?

2) Where does the Calvin Benson cycle happen?

• Marked the lab questions


• Went over photosynthesis practice questions


• Marked a photosynthesis diagram


• Looked at noncylclic photophosphorylation


• Got handed the "Candy Lab #2" sheet (will be doing it tomorrow)


• Watched a movie called "Cycle of Life" which was on photosynthesis

Thoughts and Questions:

I like studying photosynthesis because I find it pretty easy.

Where does the Calvin benson cycle happen?

Above and Beyond:

Where does the Calvin Benson cycle occur?

It occurs in the stroma of the chloroplasts.

Here is a picture that I found on google of the Calvin Benson Cycle

Gas, transport, exchange in respiration
Questions

Opinions

Respiration is one of many amazing things that the bopdy does for you for free and you don't have to even work for it but really you because its your body. I find this unit kind of interesting but it is difficult to understand if you don't pay attention. The one thing i don't get is how your body can move the diaphram to create a sort of vaccum to carry air in and out of the body. I always thought you sucked air in on your own will.

Additional

I went on google.com and found so really interesting facts on respiration but i wont give them all to you because that would make people stop asking questions.

• Central to the human respiratory system, they breathe in between 2,100 and 2,400 gallons (8,000 and 9,000 liters) of air each day—the amount needed to oxygenate the 2,400 gallons (9,000 liters) or so of blood that is pumped through the heart daily.
• An adults lungs cotain 600 million alveoli

Class Review

- Got prepared for lab.

- Started lab for dissection of the heart.

Thoughts And Opinions

At first, the heart looked really disgusting!! It was full of fat and not what a heart was supposed to look like, well what I thought. It was really tough to get through, tougher than I thought. The muscles actually work I guess. It amazed me by how different the heart looked from the pictures that we got. It was completely different!! Overall, it was a fun class and I learned a lot from it.

Additional Insight

http://www.pbs.org/wgbh/nova/heart/pioneers.html

One of the first surgeons to use these improved techniques to gain access to the heart was Dr. Dwight Harken, a young U.S. Army surgeon. Many of Harken's patients were young soldiers evacuated from the European front with shell fragments and bullets lodged inside their hearts. To leave the shrapnel in was dangerous, but removing it was almost surely fatal. Harken began operating on animals, trying to develop a technique that would allow him to cut into the wall of a still beating heart, insert a finger, locate the shrapnel and remove it. All of his first 14 animals subjects died. Of the second group of 14, half died. Of the third group of 14, only 2 died. Harken felt ready to try the technique on humans. All of his patients survived, proving that the human heart could be operated upon.

It was very complicated to find all of the valves and parts of the heart when I did it on a sheep heart. I can't even imagine how hard it would be for a doctor to do an open heart surgery! Especially so long ago with no technology. That is impressive.

Class Summary
-Review heart sounds from last class
-Watch short movie clip (of a heart beating)
-Read pages 331-334 (exercise adjustment) and 338-339 (lymph system)
-Blood Assignment due Wednesday (Dec.12th)
**Homework**-Make labels for tomorrow's heart dissection (put tape over them)

Thoughts and Opinions
The more I think about the heart, the more grossed out I get about it. There are so many different parts and something could easily go wrong and stop your heart from beating. After going to bio class, I'm more aware of my heart beating and it makes me really uncomfortable. To me, this unit is a lot more interesting and useful than cellular respiration/ photosynthesis ever will be. I'm really excited about the heart dissection tomorrow!

Above and Beyond (Heart Facts)
-According to German researchers, the risk of heart attack is higher on Monday than any other day of the week.

-By the time you turn 70, your heart will have beat some two-and-a-half billion times (figuring on an average of 70 beats per minute.)

-Women's hearts beat faster than men's.
