Are made in the renal medulla
Lead to pain & fever
Can only constrict blood vessels
Prostaglandins can constrict AND dialate vessels
What are the differences between
Endocrine hormones are created at a descrite site and sent to act upon another
Paracrine signalling is when the target cell is near the signal releasing cell (para = near)
Autocrine signalling is when the target cell is itself
Prostaglandins are either paracrine or autocrine signalling

- 0-3 Strong acid Red
- 3-6 Acid Orange/Yellow
- 7 Neutral Green
- 8-11 Base Blue
- 11-14 Strong base Purple
Litmus paper that is blue will turn / stay ________ in the presence of a strong base
Which of the following is not a function of the kidneys?
What is the the Ideal Gas Law?
What is its formula?
- The ideal gas law is the equation of state of a hypothetical ideal gas.
- It is a good approximation to the behavior of many gases under many conditions
- It has several limitations
- PV=nRT or PV=knT
What is Archimedes Principle?
The object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object
Any floating object displaces its own weight of fluid
What is Charle's Law?
- aka "The Law of Volumes"
- Gas expands as its temperature increases
What is Boyle's Law?
aka Boyle-Mariotte Law
- A fixed amount of an ideal gas kept at a fixed temperature
- P [pressure] and V [volume] are inversely proportional
- while one doubles, the other halves
k is a constant value representative of the pressure and volume of the system
What is Anderson's Rule / Anderson's Principle?
When constructing an energy band diagram, the vacuum levels of the two semiconductors on either side of the heterojunction should be aligned (at the same energy)
In chemistry, ________ is the tendency for a substance to vaporize.
What does it mean if a liquid is the following?
- Viscous / Viscosity
- - The resistence of a liquid that is being deformed (harder or easy to pour)
- Volatile / Volatility
- - Tendency for a substance to vaporize
- Evaporative / Evaporation
- - Vaporization of a liquid that occurs only on the surface
- - NOT the same as boiling which occurs on the entire mass of the liquid
- - A nonperiodic signal of short duration
- - A decaying signal, wave, or oscillation
- - Has nothing to do with liquids
Albert Michelson is...
- First American to win a Nobel Prize in science
- Measuring speed of light
A Fundamental Wave / Frequency is...
- Abbreviated as fo
- The lowest frequency of a periodic waveform
- Lowest frequency sinusoidal in the sum.
Any frequency higher than the fundamental frequency of a sound
High frequency sound waves are known as__________
Consonance vs Dissonance Waves
- - Considered stable (at rest)
- - Combo of notes that sound pleasant when played at the same time
- - Considered unstable (or temporary, transitional)
- - Combo of notes that sound harsh or unpleasant
What is a Lewis Acid? A Lewis Base?
Usually defined within terms of a chemical reaction
- Lewis Acid is an electron pair acceptor
- Example: H+ is a Lewis Acid because it can accept a lone pair completing its stable form
- Lewis Base is an electron pair donator
- Examples: OH− & NH3
NaCL is considered a _______ bond
Forces can be indicated on graph paper by the use of ______
Which is not a primary color of light?
What do these measure?
- Newton - Force
- Coulomb - Charge
- Joule - Work
- Watt - Rate of energy conversion / transfer
A(n) ________ is a device used to measure current
A __________ is a compact type of particle accelerator in which charged particles in a static magnetic field are travelling outwards from the center along a spiral path and get accelerated by radio frequency electromagnetic fields.
Ohm's Law states that
The current through a conductor between two points is directly proportional to the potential difference across the two points
A ______ is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
A____________ is a passive two-terminal electrical component used to store energy in an electric field.

_______ is the current flow of one coulomb per second
Which is NOT considered a type of radiation ray?
Which of the following describes the should joint?
Ball & Socket Joint
Ball & Socket Joint
Rickets is associated with ______ deficiency
What is Newton's Second Law of Motion?
F = ma
- The net force applied to a body produces a proportional acceleration.
- If a body is accelerating, then there is a force on it.
What is Newton's First Law of Motion
- An object that is at rest will stay at rest unless an unbalanced force acts upon it
- An object that is in motion will not change its velocity unless an unbalanced force acts upon it.
What is Newton's Third Law of Motion?
- All forces are interactions between different bodies
- No such thing as a force that acts on only one body
- Forces of two bodies on each other are always equal and are directed in opposite directions
"To every action there is always an equal and opposite reaction"
