Anatomy and Physiology
Term | Definition |
---|---|
Matter | A physical substance that has mass and occupies space. |
List three subatomic particles and their charge...if they have one. | Protons (+), Neutrons (=), and Electrons (-). |
Ionic Bonds | One atom donates an electron to another atom that needs it to complete a shell |
Covalent Bonds | Electrons are donated by each atom to complete the Octet rule. |
Hydrogen Bonds | Happen between adjacent molecules, not atoms |
What is the difference between reactants, products, and metabolism? | Reactants are going through a chemical reaction, products are the outcome of the reaction, and metabolism is how many reactions are taking place at a given moment. |
Name 3 types of energies and what they are referring to. | Kinetic energy is motion energy, potential energy is stored energy, and chemical energy is potential energy stored in chemical bonds. |
Name all 4 types of chemical reactions. | Decomposition (includes hydrolysis), synthesis (anabolism), reversible reactions, and exchange reactions |
What is the difference between organic and inorganic compounds? | Organic compounds are based on Carbon and Hydrogen, Inorganic are not. |
Anatomy | Describes the structures of the body: what they are made of and where they are located. |
Physiology | The study of anatomical structures/ individual and cooperative functions. |
Name the levels of organization in order. | Chemical molecular level, cellular level, tissue level, organ level, organ system level, and organism level. |
Homeostasis | All body systems working together to create a stable internal environment. Also a state of equilibrium. |
Negative Feedback | The response of the effector negates the stimulus, returning it back to normal homeostasis. |
Positive Feedback | The response of the effector exaggerates and enhances original stimulus, pushing away from homeostasis. |
