body system
| Question | Answer |
|---|---|
| metabolism | the body's use of molecules for energy and growth |
| glucose | a molecule that organisms can use to release energy and that is made of carbon, hydrogen, and oxogen atoms |
| oxogen | a molecule that organisms get from the air or water around them and use to release energy |
| amino acids | molecules that are building blocks of proteins |
| system | a set of interacting parts forming a complex whole |
| digestive system | the body system that takes in food and breaks it down |
| respritory system | the body system that takes in oxogen and releases carbon dioxide |
| circulatory system | the body system that transports molecules to and from all the cells of the body |
| energy | the ability to make things move or change |
| protein | a category of large molecules that preform important functions inside living things |
| startch | a type of energy storage molecule made of many glucose molecules connected together |
| tissue | a group of cells that work together to perform a specific job |
| heart | muscular organ that pumps blood throughout the body |
| arteries | blood vessels that carry oxogen rich blood from the heart to the body |
| veins | blood vessels that return oxogen poor blood back to the heart |
| capillaries | tiny blood vessels where the exchange of oxogen, carbon dioxide, carbon dioxide, nutrients and waste occurs between the blood and the cells |
| circulation | movement of blood through the heart and blood vessels delivering oxogen and nutrients to the body and removing waste products |
| lungs | main organ of the respritory system where gas exchange occurs |
| diaphram | muscular structure that separates the chest cavity from the abdominal cavity and plays a key role in breathing |
| alveoli | tiny air sacs in the lungs where the exchange of oxogen and carbon dioxide take place |
| indigestion | proccess of taking food into the body |
| digestion | the process of breaking down food into its smallest parts |
| respiration | process by which oxogen is taking in and carbon dioxide is released by an organism |
| excretion | to remove waste |
| homeostasis | the body's ability to maintain a stable internal environment even when external change conditions change |
| voluntary | you need to decide on the action before it happens, done by choice |
| involuntary | happens without you thinking about it, occurs automatically |
| smooth muscle | type of muscle found in internal organs that operates involuntary example the muscle that makes up the esophagus |
| cardiac muscle | type of muscle tissue that makes up the heart and operates involuntary |
| cellular respertaion | the chemical reaction between oxogen and glucose that releases into cells |
