Topic 3 Human Body Systems Lesson 2 Systems Interacting
| Question | Answer |
|---|---|
| Which systems work together to aid in movement? | the Skeletal System, Muscular System and Nervous System |
| How do the Skeletal System, Muscular System and Nervous System aid in movement? | muscles attach to bones to move them; the nervous system controls when and how your muscles act on the bones |
| Which systems control body functions? | the Nervous System and Endocrine System |
| How do the Nervous System and Endocrine System control body functions? | the nervous system uses electrical signals and the endocrine system uses chemical signals (hormones) to control body processes |
| What is the function of blood vessels? | they carry oxygen, nutrients, carbon dioxide an waste to and from every cell of the body |
| How do the Circulatory and Respiratory Systems work together? | blood interacts with the lungs to pick up oxygen and release carbon dioxide |
| How do the Circulatory and Digestive Systems work together? | the small intestines send nutrients into the bloodstream |
| How do the Circulatory System and kidneys work together? | blood passes through the kidneys to be filtered |
| How to stimulus and response work together? | senses allow you to react to changes in the environment |
| How do the Nervous and Digestive Systems work together? | they release saliva when food is observed |
| What is the function of the Endocrine System? | chemicals are released from the endocrine glands to control body processes |
| How do hormones interact with the Excretory and Circulatory Systems? | to control the amount of water in the bloodstream |
| How do hormones interact with the Digestive and Circulatory Systems? | to control the amount of sugar in the blood |
| What is homeostasis? | it is the maintaining of a stable internal environment when the outside environment changes |
| How does your body regulate temperature? | the nervous system sends signals to the skin and muscles to produce goosebumps when it is cold; the nervous system sends signals to sweat glands to release sweat when it is hot |
| How does your body keep balance? | a structure in the inner ear senses your position; information is sent to your brain; the brian sends information to muscles to keep you steady |
| How does your body meet its energy needs? | hormones from the Endocrine System signal the Nervous System to make you feel hungry |
| How does your body maintain water balance? | if cells need more water, the Nervous System causes you to feel thirsty; signals are sent to the muscles and Skeletal |
