Muscle movement disorder which is called dystonia can be caused by several different reasons such as trauma. Dystonia is a disorder where your brain cannot control your muscles

The central nervous system consists of the brain and spinal cord and serves as the collection point of nerve impulses. The peripheral nervous system includes all nerves not in the brain or spinal cord and connects all parts of the body to the central nervous system. The peripheral (sensory) nervous system receives stimuli, the central nervous system interprets them, and then the peripheral (motor) nervous system initiates responses.

It was very interesting to realize what kidneys do to our blood. First, blood comes in the kidney through the veins. Then inside the kidney blood concentration is balanced out. Also kidney filters out the harmful substances so our blood can be clean. Then through the arteries, it flows back to the heart. It was amazing to see how this organ can remove the unwanted materials and control the concentration of the blood.

Alveoli is an air sacs that are located at the end of the bronchioles. Their job is to receive oxygen and provide it to the blood sells. After our blood circulates in our body and pick up CO2 they arrive at alveoli again. They drop their carbon dioxide in the alveoli and it carries Co2 to our lungs to send it out of our body. If our alveoli gets damaged, gas changed cannot happen properly. As a result, we will have shortness of breathe.

Diaphragm is the large muscle located beneath the lungs .It is for seperating between the respiratory and the digestive system. But it's main function is for respiration. without it we can't breath because it contracts and moves down to make us inhale and goes upward and expands to make us exhale. The reason why diaphragm is so important in the process of breathing is because it creates a air pressure in our lungs. This condition makes the air come and escape from our lungs so without diaphragm our breathing cannot function properly.

To record your observations there are several ways. As mentioned up there, pictures, table and graph can be effective way to record your observations. Another way is to video tape. By video taping we can even record the sound of the experiment as well as visual representation of the experiment. It is important to be careful when recording a observation because wrong observation could lead wrong results. Since your conclusions are based on your results, wrong observation could mess up the whole experiment.

Analysis is the step of the scientific method where data is interpreted. We examine their trends and cause and effect relationships. During analysis, scientists evaluate if they have enough data to continue to interpretation. They review and make sense of the data collected during the experiment. A conclusion is where you answer your research questions and decide whether your data prove or disprove your hypothesis. A good element of conclusion would be explanation of the results using scientific knowledge. Also a statement including whether my data agrees or disagree with the hypothesis and accuracy of the data. By writing down an analysis before conclusion, a trend of our data can be recognized so summary can be easily written. it helps people to write down concise conclusion. Also from the analysis of the data we can comment on the reliability of the data because if our data does not make sense scientifically we cannot say that our data is reliable. Elements of good analysis are trend of our data, explanation of the data, and accuracy of the data.

Hypothesis is an educated guess based on your knowledge about the experiment. This educated guess must be written before the experiment because it is a prediction you make on the results of a experiment. A good hypothesis means it should be testable, which is called a testable hypothesis.Also It specifies the relationship between the values of two or more variables. Testable hypothesis should be simple so it is test can be done to either prove your hypothesis or disprove your hypothesis.

Diseases of respiratory system Asthma causes breathing difficulty. Also lung cancer caused by cigarette smoke. Some other ailments involving the respiratory system are respiratory infections, including tuberculosis, pneumonia and influenza.
