Immune System

Function: The function of the immune system is to keep you health and safe. It does this by remembering the sicknesses you get so the next time they come to attack your bod, your body is able to fight it off.

Organ's:
Spleen: Old red blood cells get sent to the spleen to be recycled. In the mean time white blood cells are stored in the spleen. The Spleen can fight bacteria related to Pneumonia.
Bone Marrow: Bones marrow is where red blood cells are created and produced. The bone marrow is responsible for creating T cells. The bone marrow also creates the cells in body.
Thymus: The Thymus receives T cells that are not mature yet and train them to do their function. The T cells come from the bone marrow.
Lymph Nodes: Lymph Nodes act as filters. They filter germs that could potentially make you sick. Lymph Nodes include a small tunnel/channel system inside this small system the tunnels contain white blood cells.
Tonsils And Adenoids: The Tonsils and Adenoids have almost the same function. They are responsible for capturing and trapping viruses and bacteria.
Skin: The skin is the top layer of our body and its used to protect our bodies and our inside and tissues. It also help to prevent viruses and bacteria and other harmful things to your body.
Appendix: The appendix is very helpful towards your body because its full of a special bacteria that helps you digest your food. And if your body is under attack and some important bacteria gets extinguished the appendix will step in and can act as a replacement.

Interaction With Other Systems: 
The Immune System works with the circulatory system in order to transport lymphocytes.  And the pathways the circulatory system provides help the Immune System cells travel through your body quickly. The Immune System also works with the Digestive System because the appendix has the job of being able to digest food with a special type of bacteria.
Analogy:
My analogy is a library because thats how you Immune System is its like a library full of books each one containing a file of a sickness or germ that the Immune System defeated. This is so that when the sicknesses or germ comes back you and your Immune System will be able to fight it. These books with the germs "weaknesses" written on it helps when the real sickness/disease causing germ comes so we can fight it.
Structure And Function: 
Skin is designed to be the first guard of your body. The skins structure is very strong and thick this help your body stay safe and your inside intact. Only a very major and deep injury could pass through the skins structure. The main function for the skin is to protect your insides and be the first protecter to germs and outside materials. You skin is rough which makes it that only something sharp or a hard hit would actually make you bleed.

Mitosis 10/14/16

Summary:

The process of the cells dividing is called Mitosis. Mitosis is what causes cell division. There are six different phases. These six phases are Interphase, Prophase, Metaphase, Anaphase , Telophase and Cytokinesis. 

There is also different types of body systems that help us live and breath today. The systems are the Cardiovascular System, Digestive System, Immune System,Muscular System, Nervous System, Skeletal System, and the Urinary System.

S&EP: SP2: Developing And Using Models:

We made a model of a Mitosis flip book in class. A flip book is a small book that has drawing drawn on them and when you flip the book quickly it becomes a miniature animation. And for our animation  we had to draw the many different stages of Mitosis. We had to draw the little cells while they did their cell division. It was challenging but in the end it was fun to see the result and witness mitosis in our eyes.

XCC: Cause and Effect:

 The cause and effect is once the cell matures and grows it starts the stages of Mitosis. The first thing it does is it duplicates its DNA so the other cell can have the same DNA and not just half. Once the cell has duplicated its DNA correctly it begins the rest of the Mitosis process. But sometimes the cell could duplicate itself wrongly and that could cause uncontrollable duplication/division of cell. This uncontrollable division/duplication can cause cancer. And cancer could possibly lead to death.

Cell Cycle 10/7/16

Summary:

The Interphase the cell starts to grow and mature.The DNA doubles. During Phosphase the Nucleus disappears and the chromatin starts to condense and the spindle fiber forms between the centrids. In Metaphase the spindle fibers get connected to the chromosome while the move to the center of the cell.Anaphase is when the centromeres split and the spindle fibers pull the sister chomeotides to the opposite poles. Telophase is when the nuclear membrane begins to form and the cell start to split in two.Cytokinesis is when the cytoplasm and cell splits in two and two daughter cells form and one goes to one cell while the other goes to the other cell.This is called Mitosis or the Cell Cycle.

SP6:Constructing Explanations And Designing Solutions:

On a worksheet I attempted to explain the way Mitosis works and what it is. I said the Mitosis is the 6 step process the cell goes through to split in half or divide. The cell goes through these 6 steps rather quickly and its appearance changes very quickly (inside).The process goes in 6 phases like I said Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokenesis.

Stability And Change:

The change thats happening is the actual cell itself because its going through 6 phases which lead to the cell splitting in 2. The name of the 6 phases are Interphase, Prophase, Metaphase,Anaphase,Telophase,and Cytokenesis. All these phases lead to the cell splitting in two. This process can be called cell division,the cell cycle, or mitosis. Before anything the cell MUST copy DNA so the cell that is about to split doesn't receive only half of the DNA code.
