MetABOLISM
| 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 oxygen atoms |
| Oxygen | A molecule that organisms get from the air water around them and use to release energy |
| Amino acids | Molecules that are building blocks of protein |
| System | A set of interactting parts forming a complex whole |
| Digestive system | The body system that takes in food and breaks it down |
| Respiretory system | The body system that takes in oxygen and releases carbon dioxide |
| Circulatory system | The body system that transports molecules to and from all cells of the body |
| Energy | The abillity 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 cpecific 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 to the heart |
| Capillaries | Tiny blood vessels where the exchange, of oxygen, carbon dioxide, nutriens and waste occurs between the blood and removing waste products |
| Lungs | Main organ of the respiratory system where gas exchange occurs |
| Diaphgram | Muscular structures 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 takes place |
| Ingestion | Process of taking food into the body |
| Digestion | Process of breaking food down into its smallest parts |
| Respiration | Process by which oxygen is taken in and carbon dioxide is released by an organism |
| Excretion | To remove waste |
| Homeostasis | The ability's to maintain a stable internal environment even when external conditions change |
| Voluntary | 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 involuntarily ( you dont 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 involantarily (you dong have to think about it for it to happen) |
| Cellular Respiration | The chemical reaction between oxygen and glucose that releases energy into cells |
