science metabolism
| Question | Answer |
|---|---|
| Metabolism | The body 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 or water around them and ise to release energy |
| Amino acids | Molecules that are the building blocks of proteins |
| System | A set of interating 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 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 form the heart to the body |
| Veins | Blood vessels that return oxygen poor bloodback to the heart |
| Capillaries | Tiny blood vessels where the exchange of oxygen carbon dioxide nutrients and waste occures between the blood and the cells |
| Circulation | Movement of blood through 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 occcurs |
| Diaphragm | Muscular structure that separtes 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 its smallest parts |
| Respiration | Process by which oxygen is taken in and carbon dioxide is released by an organism |
| Exce=retion | To remove waste |
| Homeostasis | The body ability 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 itjust happens example the muscle that makes up the esophagus |
| Cardiac muscle | Type of muscle tissue that makes ip the heart and operates involuntarily you dont have to think about it for it to happej |
| Cellular respiration | The chemical reactions between oxygen and glucose that releases energy into cells. |
