Body System/Metaboli
| Term | Definition |
|---|---|
| Metabolism | the bodies use of molecules for energy and growth |
| Glucose | a molecule that an organisms can use to release energy and that is made of carbon hydrogen and oxygen atoms |
| Amino Acids | molecules that are building blocks of protein |
| oxygen | a molecule that organisms get from the air or water around them to use to release energy |
| system | a set of intersecting Parts forming a complex whole |
| digestive system | the body system that takes in food and breaks it down |
| respiratory system | the body system that takes an oxygen and releases carbon dioxide |
| Circulatory system | the body system that transports molecules to and from all cells of the body |
| energy | the ability to make things move or change |
| protein | a category of large molecules that perform important functions inside living things |
| starch | 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 oxygen rich blood from the heart to the body |
| veins | blood vessels that return oxygen poor blood back into the heart |
| Capillaries | tiny blood vessels where the exchange of oxygen carbon dioxide nutrients and waste occurs between blood and the cells |
| circulation | movement of blood throughout the heart and blood vessels delivering oxygen and nutrients to the body and removing waste products |
| lungs | main organ of respiratory system where gas exchange occurs |
| Diaphragm | 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 oxygen and carbon dioxide take place |
| ingestion | process of taking food into the body |
| digestion | process of breaking food down into the smallest parts |
| Respiration | process by which oxygen is taken in in carbon dioxide is released by organism |
| Excretion | to remove waste |
| Homeostasis | the body's ability to maintain a stable internal environment even when external conditions change |
| voluntarily | you need to decide on the action think it before it happens done by choice |
| involuntary | happens without you thinking about doing it occurs automatically |
| smooth muscle | type of muscle found in internal organs that operates involuntary you don't have to think about it it just happens example the muscle that makes usexample the muscle makes up the esophagus |
| Cardiac muscle | type of muscle tissue that makes up the heart and operates and voluntarily you don't have to think about it before it happens |
| Cellular respiration | the chemical reaction between oxygen and glucose that releases energy into the cells |
