| Term | Definition |
|---|---|
| Metabolism | the body is used of molecules for energy |
| glucose | molecule that organisms can use to release energy and that is made of carbon hydrogen and oxygen atoms |
| oxygen | a molecule that organisms get from the air or water around them and used to release energy |
| Amino acids | molecules that are building blocks for proteins |
| system | a set of interacting 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 in oxygen and releases carbon dioxidewhat what special this weekend |
| circulatory system | body system that transports molecules to and from all cells of the body |
| energy | 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 or blood back to the heart |
| capillary | tiny blood vessels where the exchange of oxygen carbon dioxide nutrients and waste occurs between the 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 the respiratory system where gas exchange occurs |
| diaphragm | muscular structure that separates the chest cavity from the abdominal cavity and plays a key role in bre |
| Aveoli | tiny air shocks in the lungs with the change of oxygen and carbon dioxide take place |
| ingestion | process of taking food into the body |
| digestion | doesn't breaking food down into its smallest part |
| respiration | cautious by which oxygen is taken in in carbon dioxide is released by an organism |
| exretion | to remove waste |
| Homeostasis | body's ability to maintain a stable internal environment even when external conditions change |
| voluntary | you need to decide on the action (think it)s before it happens done by choice |
| involuntary | happens without you thinking about doing it occurs automatically |
| smooth muscle | type of muscle found in internal organism that's operates involuntarily (you don't have to think about it it just happens) example the muscle that makes up the esophagus |
| cardiac muscle | type of muscle tissue that makes up the heart and operates involuntarily (you don't have to think about it for it to happen) |
| cellular respiration | the chemical reaction between oxygen and glucose that releases energy into cells |
