35 Cards in this Set

  • Front
  • Back
Which element by number is the largest in the body
Hydrogen
Which element is largest by mass within human body?
Oxygen
Teleological approach
why it's there
Mechanical approach
how it physically got there
Physiology
study of the mechanisms by which living organisms function
List the organization of the body
cells-tissues-organs-systems-whole body
List the 4 types of tissues
epithelial, nervous, muscle, connective
intracellular fluid
fluid located in the cell of a human body
extracellular fluid
fluid located outside the cells of human body. Made up of interstitial fluid and plasma
List the components that make up the extracellular fluid
plasma
inter stitial fluid
What is plasma and where is it located?
liquid portion
flows in blood canals
What creates the environment for the cells
Fluid
homeostasis
maintenance of a relatively stable internal environment
How does the body maintain stability?
homeostasis-interstitial stays stable by interacting with plasma. Plasma stays stable by interacting with organs
List the factors that the body homeostatically controls
Concentration of nutrients
Concentration of gases
Concentration of wastes
Concentration of salts/water: Osmolarity
Temperature
pH
Pressure and volume
What is meant by stability?
Balance of inputs and outputs. Complete constancy is not maintained, only a narrow range. Not everything is homeostatically maintained so variables are ranked in heirarchy
negative feedback loop
regulatory mechanism in which a change in a controlled variable triggers a response that opposes the change. Two types-intrinsic & extrinsic
What are the types of control
intrinsic
extrinsic
positive feedback loop
regulatory mechanism where a change in a controlled variable triggers a response that continues to drive the variable farther from set point.
List the types of chemical bonds
ionic
covalent
hydrogen
covalent bond
strong chemical bond where 2 atoms share electrons. Most common
nonpolar bond
equal sharing of electrons between atoms (no poles)
polar bond
unequal sharing of electrons between atoms (poles/ends) Partial pos. partial neg
ionic bond
electrical attraction between two atoms. Weak and forms crystal latic
which bond forms a crystal latic?
ionic
Which bond is the strongest?
covalent
hydrogen bond
weak electrostatic attraction between an electronegative atom and a hydrogen atom covalently linked to a sencond atom- very weak
Why do hydrogen bonds form
occur because of polarity: part. pos. and part. neg.
Why is water a great solvent for ions and polar molecules?
It's polarity attracts them
hydrophobic
substance that repels water (have non-polar bonds)
Are lipids hydrophobic or hydrophilic?
hydrophobic
Is glugose hydrophobic or hydrophilic?
hydrophilic
hydropphilic
substances that are attracted to polar water molucules
Are polar bonds associated with hydrophobic or hydrophilic?
hydrophilic
Are nonpolar bonds associated with hydrophobic or hydrophilic?
hydrophobic
