Science Mid-term
| Question | Answer |
|---|---|
| The averageof a given set of data. Determined by adding the values together, then dividing by the total number of values. | Mean |
| The middle number of a given set of data. Determined by putting the values in order (least to greatest) and choosing the middle number. In the case of two middle numbers, find the mean of the two. | Median |
| The value that occurs the most often in a given set of data. If there are 2 values that occur the most often, it is bi-modal. If all values occur equal amount of times, there is "no mode." | Mode |
| The difference, or distance, between the lowest and highest values in a given set of data. Determined by subtracting the lowest value from the highest value. | Range |
| 1-______, 2- Childhood, 3-______, 4- Young adulthood, 5-_________ | 1- Infancy, 3- Adolescence, 5- Older adulthood |
| What is the function of the nervous system? | It voluntarily or involuntarily controls functions of the organs. |
| What are the major organs of the nervous system? | brain, spinal cord |
| What is the function of the respiratory system? | It supplies oxygen and removes carbon dioxide. |
| What are the major organs of the respiratory system? | lungs, diaphragm, mouth, nose |
| What is the function of the skeletal system? | It provides support and shape. |
| What are the major organs of the skeletal system? | bones, cartilage, joints |
| What is the function of the muscular system? | It provides movement of the body. |
| What are the major organs of the muscular system? | muscles, tendons |
| What is the function of the digestive system? | It turns food into energy. |
| What are the major organs of the digestive system? | stomach, intestines |
| What is the function of the circulatory system? | It provides blood and oxygen to the body. |
| What are the major organs of the circulatory system? | heart, blood vessels |
| What is the function of the endocrine system? | It produces hormones. |
| What are the major organs of the endocrine system? | pancreas, glands |
| What is the function of the urinary system? | It rids body of excess salts and water. |
| What are the major organs of the urinary system? | kidneys, bladder |
| What is the function of the excretory system? | It eliminates waste from the body through the respiratory system (rids body of carbon dioxide), urinary system (rids body of excess salts and water), epidermal system (cools body down through sweat), and digestive system (rids body of food wastes) |
| How does the respiratory system use oxygen? | It takes in oxygen to use in all body systems. |
| How does the circulatory system use oxygen and glucose? | It pumps oxygen through blood to all parts of body; glucose is used to create blood. |
| How does the digestive system use oxygen and glucose? | It breaks down glucose to create energy. |
| How does the nervous system use oxygen and glucose? | The brain is the largest oxygen user in your body- used to keep brain cells alive; brain uses glucose as fuel to create energy. |
| How does the muscular system use oxygen and glucose? | The muscles use oxygen to work; when oxygen runs out, the muscles break down glucose. |
