Summary:
Cells growing and dividing is known as the cell cycle or cell division. There are quite a few steps to this process and they are interphase, prophase, metaphase, anaphase, telophase and cytokinesis. During interphase cells grow, copy their DNA, and prepare for division. The specific process in which cells copy their DNA is replication. During prophase the chromatin condenses into chromosomes. When metaphase takes place the chromosomes line up across the center of the cell. As anaphase occurs, the centromeres split and the chromatids separate. A nuclear cover forms around the chromosomes during telophase. Through cytokinesis, the cytoplasm splits moving organelles into the new cell. The DNA is copied before mitosis occurs to insure the new cell has the correct genetic information. Phosphate and deoxyribose make up the two sides of DNA. Cell division is the very complex cycle of cells dividing.

For the next two weeks there will be no weekly blogs due to the fact that I am going to write 8 new blogs for each body system. I have went back, read, and am going to rewrite all my previous body system blogs which I wrote in the fifth grade. I have already written and improved my digestive system blog. I find some of the new information we have to include in our blogs is a wonderful way to communicate information help both the writer and reader better understand the topic. In our new body system blogs we must include an analogy that represents the body system or an organ in that system. Thinking of how each organ is portrayed in real life allowed me to grasp its real function. For example, I said the esophagus reminds me of a water slide because it transports water and people from the top to the bottom. The start of the slide is the mouth, the end is the stomach, and the person is the chewed food. I think communicating information in the form of an analogy is extremely helpful and shows the content in more than one way.
XCC-Systems and System Models:
Organelles. Cells. Tissue. Organs. Body Systems. The Body. The reason your body functions the way it does is because of the body systems that make it up. Each body system has a specific function and organs that keep your body up and running. The nervous system controls you voluntary and involuntary actions and senses. The organs that make up the nervous system are your brain, spinal cord, and your nerves. The urinary system expels liquid or soluble waste. The organs in this system are your kidney, ureters, bladder, and urethra. Those are just two examples of organs and functions a few body systems do. Previously, we did activities which are helping me understand the topic today. When we made a system model for the muscular system we traced our hand onto a paper. Then, we attached string to a chosen finger. When you pulled on the string it moved the hand representing voluntary movement. We also modeled the digestive system. We put crackers in a bag- into the mouth, crushed them- chewed, added water -saliva, and then it went into the esophagus. After it went into the stomach, coke-acids were added to this mixture. It went into the small intestine which took some liquid and nutrients. The large intestine and they separated the rest of the liquids and solids. It went into the rectum and lastly the anus. These system models helped me understand these systems. I am glad I went back to check my previous blogs, I believe it will help me writing the new ones.

This week I was a mutant, to be more specific a learner. This is because I wanted to know as much information I could on the digestive system.
