Body System Interactions Worksheet Answer Key – System Interactions Structure and Function of Animals in Real Life All living systems, including the human body, work together to keep living things healthy and alive. Although each system has its own functions, all of them are combined and complement each other, as you have described and written in an effective and efficient way of the system. Part I: System Interaction / Features system download map / features and interaction maps. Select the contact map. Relate system/component maps to defined maps. Check the operating system and each card number in the table below. Continue linking interaction maps to system/component maps until you have written system interactions for each interaction map.

System Interactions The structure and function of animal systems in real life, continued Part III: Paperclip Lessons Now it’s time to involve and analyze the interacting systems in your body. Directions: Find an alligator clip for your teacher. Hold a piece of paper in your hand and write. Ask your partner to set a stopwatch for 30 seconds. When your partner says go, open and close the paper clip as many times as possible, counting each time it is opened complete, in 30 seconds. Enter the number in the data table. Repeat this process for 5 consecutive trials and record the number of strokes after each trial. DO NOT shake hands between each test. Fact sheet: Number of alligator clips clicked every 30 seconds How did your fingers feel in test 1 vs. 5? ________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________ Number of Stress Tests 1 2 3 4 5

2 Find: Interactions and Running Lesson 7 Instructions: The next section contains descriptions of running. Under each paragraph, write the related body system. Running Running is an activity that requires the coordination of many body systems together. Runners preparing for races eat a lot of pasta and potatoes. Pasta and potatoes contain carbohydrates, which are the main source of muscle energy. Carbohydrates are finally broken down into sugars. Glucose enters the villi of the small intestine and passes into the bloodstream to be transported to cells. When a runner starts running, the rate of breathing increases. The runner begins to breathe deeply and rapidly. In addition, the heart beats faster. This results in more oxygen being delivered to the cells. Running requires a lot of coordination, which is achieved by shortening and relaxing many muscles. The brain sends a message to the muscles, causing them to contract or relax. In response to brain signals, muscles contract and expand. The proper coordination of the muscles that pull the bones together provides movement. Cells produce carbon dioxide. Carbon dioxide is a pollutant. Carbon dioxide travels with the blood to the lungs. The lungs exchange gases and waste products are removed when the lungs are exhaled. In addition to carbon dioxide, body cells produce metabolic waste. Waste is filtered from the blood and collected by the kidneys as urine. Urine is stored in the bladder until it leaves the body. During running, the runner’s body temperature rises. Body temperature is controlled by the sweat glands of the skin. Moisture leaves the skin and provides a cooling effect. The coordination of all body systems helps to maintain homeostasis.

3 Define: Physical Interactions Lesson 7 Animals must maintain a balance between their internal and external environments. This measure is maintained through the system process. The immune system works to perform functions related to regulation, absorption of nutrients, reproduction, and resistance to injury or disease. Absorption refers to the passage of nutrients from the digestive tract into the bloodstream. Digestion occurs when food has passed through several parts of the stomach and is broken down into small molecules that can be absorbed and transported to the cells. Blood flow carries molecules to cells. The main functional systems involved in nutrient absorption are the digestive and circulatory systems. Regulation is how the body’s systems work together to maintain homeostasis despite changes in the external environment. The nervous and endocrine systems help detect and coordinate responses to changes in the environment. Negative thoughts are another example of control. If blood sugar is too high, the hormone insulin is released. As a result, the liver removes sugar from the blood and stores it as glycogen. Hormones are produced by the endocrine system. Response to the nervous system through direct communication between nerves. In the example of running, the brain sends a message to the muscles to contract. These messages are sent through the nerves. The reflex arc is another example of nervous system control. It represents the stimulus as something warm produced by a neuron. Impulses travel down the nerves to the spinal cord. In the spinal cord, impulses travel through nerves. The interneuron sends a signal to the motor neuron, which in turn stimulates the muscles needed to contract, removing the negative link. Reproduction, fertilization and child development. The main systems involved in reproduction are the reproductive system, the endocrine system, the nervous system and the circulatory system. Genital organs are reproductive organs, such as testicles, scrotum, testicles, ovary, fallopian tubes, uterus and cervix. The endocrine system secretes hormones such as testosterone, progesterone and estrogen that control reproduction. The circulatory system provides nutrients to the developing baby and carries hormones. Animals have many ways to avoid danger. Skin and bones protect the body from injury. Reflexes also play a role in preventing injury. The skin is part of the internal organs, the skeleton is part of the bones, and the nervous system is part of the reflexes. Animals have many ways to protect themselves against disease. The anti-virus system responds to the attackers by detecting, attacking and destroying the attackers. Skin management; secretions of mucus, tears, sweat and saliva; and white blood cells. The immune system works closely with the rest of the body’s systems, including the gut, circulatory and lymphatic systems.

5 Activity: Describe interactions Lesson 7 Directions: Read the data and explain what happens between systems. Write your answers in your notebook. Answer Scenario Although it doesn’t happen often, it can happen in Texas. Children rush to play in the new snow and their body temperature often drops. Normal human body temperature is 37 ºC (98.6 ºF). If the temperature is too high, the proteins will not function properly. If the temperature also drops
