Human Body Interactions

Body System Basics Match each body system with its basic function. Respiratory System Brings in oxygen and removes carbon dioxide Circulatory System Moves blood to all cell to drop off supplies and pick up waste Muscular System Moves the body and materials inside the body Digestive System Takes in and breaks down food for cells to have energy Excretory System Removes cellular wastes from the blood as urine or carbon dioxide Nervous System Responsible for control of the body and communication between parts and organs Interactions Sort Identify which two body systems work together in the scenario below. Respiratory and Circulatory Oxygen is delivered to body cells Carbon dioxide is removed from the body Circulatory and Digestive Food is delivered to body cells Stomach muscles have energy to squeeze and churn food Circulatory and Nervous The brain increases heart rate when oxygen levels are low The brain makes blood vessels constrict when a threat is detected Muscular and Nervous The brain controls voluntary movement The brain can overtake the diaphragm to take deep breaths One system brings in oxygen and removes carbon dioxide while the other system delivers the oxygen around the body and removes the carbon dioxide. excretory and circulatory respiratory and circulatory digestive and muscular respiratory and muscular One system breaks down the food we eat into nutrients, the other system delivers the nutrients to the body cells. excretory and muscular digestive and respiratory circulatory and excretory digestive and circulatory One system sends a message to the other, while the other raises your hand in the air. nervous and digestive nervous and muscular muscular and circulatory circulatory and respiratory One system breaks down food into nutrients, while the other system uses the energy to help you walk and exercise. nervous and digestive digestive and circulatory digestive and muscular digestive and respiratory One system signals the body it is hungry, the other system breaks down the food that is eaten. nervous and digestive circulatory and digestive digestive and excretory excretory and muscular One system delivers blood with the wastes to the system that filters the blood and returns needed fluids. excretory and muscular circulatory and respiratory circulatory and excretory digestive and respiratory
