BPK 105 MIDTERM
Anatomy - ANSWERS--investigates the structure of the body
-relationship between the structure of a body part and it's function
-can be systemic or regional
Physiology - ANSWERS--deals with the process or functions of
living things
Goals:
(1) to understand and foreshadow the body's natural responses to
changes
(2) understand how the body controls and maintains their conditions
Organ Systems - ANSWERS--group of organs that is classified as a
unit due to their similar function
-Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic,
Respiratory, Digestive, and Urinary Systems
6 Characteristics of Life - ANSWERS-1) Organization
,2) Metabolism
3) Responsiveness
4) Growth
5) Development
6) Reproduction
Homeostasis - ANSWERS-Existence and maintenance of a relatively
constant environment within the body despite fluctuations in the
external/internal environment; includes temperature, volume and
chemical content
Negative Feedback - ANSWERS-Deviation from the set point is made
smaller or is resisted; maintains variation within a normal range
without preventing it.
Maintains homeostasis
Three Components:
-Receptor
-Control Centre
-Effector
,Ionic Bonds - ANSWERS-Transfer of electrons between atoms;
creates oppositely charged ions
Polar Covalent Bonds - ANSWERS-Electrons are unequally shared
between two atoms; results in a slightly positive charge on one side of
the molecule and a slightly negative charge on the other side
Nonpolar Covalent Bonds - ANSWERS-Equal sharing of electrons
between two atoms; has an even distribution of charges among the
molecule
Hydrogen Bonds - ANSWERS-Positive end of a polar molecule is
attracted to the negative end of another polar molecule, and vice
versa; not a chemical bond and is weaker than ionic/covalent bonds
Compound - ANSWERS-Substance resulting from the chemical
combination of 2+ different types of atoms
Dissociation - ANSWERS--Process of ionic compounds dissolving in
water causing their ions to separate from each other
-Positively charged ions are attracted to the negative ends of the water
molecule and vice versa
-Dissociated ions are called electrolytes
, Synthesis - ANSWERS--Anabolism
-Two or more reactants combine to form a larger and more complex
product
Decomposition - ANSWERS--Catabolism
-Reactants are broken down into smaller, and less complex products
Exchange reactions - ANSWERS--Reactants are decomposed then
resynthesized with its counterparts
Factors That Affect the Rate of Chemical Rxn - ANSWERS-1.
Reactants
2. Concentration
3. Temperature
4. Catalysts
pH Scale - ANSWERS-Indicates the H+ concentration of a solution
Acidity - ANSWERS-Greater concentration of H+ greater than OH-,
has a pH less than 7.0
