Fetal Pig Dissection - Discussion

I thought the fetal pig lab was pretty awesome. After you got over the initial smell and the cutness of this dead baby pig, you were able to marvel at the unique opportunity presented before you. Yes, the pig was cute and had adorable little hair on it's chin and it's life was cruely cut short for ingrateful highschool students, but I think our biology class was quite grateful to these pigs for giving their life up, so we could learn about biology. I know I was grateful. So I took full opportunity to learn as much as I could from this pig who gave up it's life so I could learn from it. It was amazing to see the interconnectedness of all the organs and also how tiny all the organs were. I was surprised to see how small the lungs and heart were and how HUGE the liver was, that was a big surprise. Our group was lucky to get a pig that was acctually very big so we had a good view of all the organs. I am very grateful to this baby pig for giving up it's life so I could learn a little bit more about the awesomeness of biology. Thanks Penelope

What is a FART?

What is a fart you ask? WELL. A fart is a very stinky and smelly hunk of air that comes out of your bum. BUT what is a fart? What is it made of? Why do you cut the cheese?


WELL.......


When you eat food, you also swallow air, which contains gases like nitrogen and oxygen. Small amounts of these gases travel through your digestive system as you digest your food.  When a person swallows too much air or eats foods that the human digestive system cannot digest easily, it becomes trapped in the stomach. The only way for this excess gas to exit the body is through the anus as a FART. Other gases like hydrogen, carbon dioxide and methane are made when food is broken down in the large intestine. All of these gases in the digestive system have to escape somehow, so they come out as farts.


The gas that makes your farts stink is the hydrogen sulfide gas. This gas contains sulfur which causes farts to have a smelly odor. The more sulfur rich your diet, the more your farts will stink.


A scientific name for a fart is flatus or flatulence.

What the hell cardiac spincter???

I love this picture way too much.

This is funny because we're going to playland and we're learning about the digestive system



Marks Reflection

I feel my mark definitely reflects my learning. I've grown up in a biology family,so I find learning about biology very easy and interesting. I don't spend my whole day studying and working my butt off, I pay attention in class and do all of my work. Having a great interest in what I am learning about definitely plays a role in my mark. I am happy to sit in class and learn something new each day and having a good mark is a bonus. I am going to keep leaning and applying a lot of the things I've learned to my everyday life. I am going to come to class with an open mind ready to learn awesome things.

DNA vs. RNA

RNA!!!!

Dun dun dun!! DNA

The birth of a PROTEIN

-The making of the protein begins with the info in the DNA
-Genes describe how to make proteins by putting the correct amino acids into a long chain
- RNA strand is made from unzipping DNA strand and making a copy, which can be sent outside of the nucleus - messenger RNA
- The mRNA is sent to a ribosome, which assembles  the proteins, by translating the genetic information.
-mRNA contains information in sets of 3 nucleotides. Each set is a code for a specific amino acid
-the specific amino acids are then brought in and joined toghether by the tRNA.
-the tRNA matches up the correct amino acids, just as DNA match up
- Ribosomes will keep reading and stringing toghether the amino acids to make a protein.

PROTEIN/LIPID/SECRETION

-The Endoplasmic Reticulum produces many of the cells proteins and lipids (proteins make on the Rough ER, which contain ribosomes), these proteins and lipids travel along the smooth and rough ER, which change the modify the molecules
- To transport them to their needed locations, vesicles bound off form the ER
- The vessicle delivers it's cargo to the golgi apparatus, by fusing with the golgi
-The golgi then modifies and packages the proteins/lipids
- Vesicles then move the protein/lipds out of the cell by fusing with the cell membrane and releasing their contents outside.

1. Nucleolus - Site of genes for RNA synthesis. Assembles ribosome's
2. Nucleus - Control center of cell. Directs protein synthesis and cell reproduction
3. Ribosome - Sites for protein synthesis. Reads RNA code and translates it into an amino acid sequence
4. Vacuole - Stores water, sugar, ions and other substances
5. Rough ER - Has ribosome's. Proteins are synthesized here.
6. Golgi Body - Packages proteins for export from cell. Post office of cell
7. Cell Membrane - Provides protection and import and export of the cell
8. Smooth ER - Packages proteins for cell transportation. Detoxify drugs in liver cells . Lacks ribosome's.
9. Mitochondria- Power house of cell. Provides ATP for cellular energy
10. Lysosomes - Digests worn out organelles . Packages of digestive enzymes
11. Cytoplasm- The material inside the cell that surrounds the organelles
12. Peroxisome - Produce hydrogen peroxide because they use oxygen to break down molecules.
13. Centriole - Helps the chromosomes to separate during cell division.

I'm sorry this is sooo inappropriate, but funny. Every thing with Howard's face is funny

Smooth Endoplasmic Reticulum is a network of tubules and extension of nuclear membranes. They lack ribosomes. One of their functions consits of packaging proteins for transport within the cell. 

Rough Endoplasmic Reticulum have ribosomes attached to their surface that synthesize proteins for the cell. Rough ER transports these proteins to the regions in the cell where it is needed.

I am a collection of Carbohydrates, Lipids, Proteins and Nucleic Acids called Roohy   

This isn't inappropriate at all.

Ms. Phillips I know what this is!

DNA Helicase is the enzyme that unzips the RNA, to it's single strand form so it can be sent outside of the cell....I think.
