Body Systems terminology
Question | Answer |
---|---|
anabolism | production and maintenance of living tissue |
carbohydrates | organic compounds used by the body to produce heat and energy |
catabolism | transformation or breaking down of substances for energy production |
element | one type of atom, such as hydrogen (H), oxygen (O), and carbon (C), calcium (Ca), phosphorus (P), sodium (Na), chloride (Cl), potassium (K), magnesium (Mg), or Nitrogen (N) |
Homeostasis | the body's system of checks and balances to maintain a constant internal environment |
Hydrolysis | dissolution of substances by water |
hypertonic solution | one with greater concentration then found in cells thereby increasing osmotic pressure |
hypotonic solution | one less concentrated the body cells thereby decreasing osmotic pressure |
isotonic solution | same concentration of body cells (0.9% NaCl) and therefore the same osmotic pressure |
lipids (fats) | organic coupounds that are insoluble in water and are used by the body for heat and energy |
metabolism | sum of all chemicals and physical activity of living tissue |
molecule | two or more elements formed by a reaction, such as water (H2O), sodium chloride (KCl), or carbon dioxide(CO2) |
PH scale | a scale of 1-14 to measure acidity (below 7.0) and alkalinity (over 7.0) |
proteins | organic living compounds necessary to build and repair tissue |
solution | homogeneous mixture of substances (solutes) in a dissolving medium (solvant) such as water |
synthesis | putting together of molecules |
