METABOLISM
| Question | Answer |
|---|---|
| metabolism | `the body's use of molecules for energy and growth |
| glucose | a molecule that organisms can use the release energy |
| oxygen | a molecule that organisms get from 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 that breaks down food |
| respotory system | the body system that takes oxygen and releases carbon dioxide |
| circulatory system | the body system that transports molecules to and from all cells in the body |
| energy | the ability to make things change or move |
| 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 |
| arteries | blood vessels that carry oxygen |
| veins | blood vessels that return oxygen poor blood back to heart |
| capillaries | blood vessels where the exchange of oxygen, carbon D, nutrients, and waste occurs between the blood and the cells |
| lungs | main organ of the respiratory system where gas exchange occurs |
| diaphragm | muscular structure that separates the chest cavity from abdominal cavity and plays a key role in breathing |
| alveoli | small 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 when body breaks down food |
| respiration | process when oxygen is taken in and carbon dioxide is released by an organism |
| excretion | to remove poop or waste |
| homeostasis | the body's ability to maintain a stable internal environment |
| voluntary | to decide on a action before it happens done by choice |
| involentary | happens when you don't think about something |
| smooth muscle | type of muscle found in internal organs that operates involuntary |
| cardiac muscle | type of muscle tissue that makes up the heart and operates involutory |
| cellular reparation | the reaction between oxygen and glucose that releases energy into cells |
