APHY 101 - Midterm Ch. 1-6
Explain the difference between the study of Anatomy and the study of Physiology - ✔✔ correct
answer Anatomy is the study of structure of body parts/Physiology is the study of function of body
parts
Name and define the levels of organization of life - ✔✔ correct answer Organelles, cells, tissues,
organs, and organ systems
Define Metabolisim - ✔✔ correct answer The sum of all physical and chemical events that obtain,
release, and utilize energy
Define Homeostasis. How does a homeostatic mechanism maintain homeostasis? - ✔✔ correct
answer The body's maintenance of a stable internal environment.
Depend on normal concentrations of water, nutrients, and oxygen, and normal body temperature
and pressure
What is meant by negative feedback? How does negative feedback affect homeostatic mechanisms?
- ✔✔ correct answer Works to correct a deviation from a set point (Tries to get back to the set
point/normal)
Describe the structure of a serous membrane - ✔✔ correct answer Smooth membrane consisting of
2 layers of epithelial cells which secrete serous fluid
What are signs of aging at the cellular level? - ✔✔ correct answer Impaired cell division and the
ability to break down and recycle worn cell parts
What is meant by anatomical position? - ✔✔ correct answer Universal body position: Standing erect,
facing forward, upper limbs at the sides, palms facing forward and thumbs out.
Explain why chemistry is an important part of the study of Physiology - ✔✔ correct answer Body
functions depend on cellular functions that, in turn, result from chemical changes
Atom - ✔✔ correct answer The smallest unit of matter that defines the chemical elements
Element - ✔✔ correct answer Fundamental substances in which all matter is composed of
, APHY 101 - Midterm Ch. 1-6
Molecule - ✔✔ correct answer 2 or more atoms may combine to form a molecule
Compound - ✔✔ correct answer A substance made from two or more elements chemically
combined
Name the bulk elements of the body - ✔✔ correct answer Carbon, Hydrogen, Oxygen, Nitrogen,
Sulfur, and Phosphorus
What do atomic number and atomic weight of an atom represent? - ✔✔ correct answer Atomic
Number is the number of protons in the atoms of a particular element/Atomic Weight is the number
of protons plus the number of neutrons in each of an element's atoms
Define Ion. How do we indicate in a molecular formula if an atom is an ion? - ✔✔ correct answer
Ions are atoms that gain or lose electrons and become electrically charged
Isotope - ✔✔ correct answer An isotope is an atom that have the same atomic numbers but different
atomic weights
Distinguish between types of chemical reactions: Synthesis, Decomposition, Exchange, and
Reversible - ✔✔ correct answer
Electrolyte - ✔✔ correct answer An electrolyte is a substance that produces an electrically
conducting solution when dissolved in water.
Acid - ✔✔ correct answer Acids are electrolytes that dissociate the release hydrogen ions in water
Base - ✔✔ correct answer A compound that produces hydroxide ions when dissolved in water
Neutral compound - ✔✔ correct answer Occurs when ions of opposite charges attract one another
to form electrically neutral compounds.
How are acid and bases represented on the pH scale? - ✔✔ correct answer Any pH number greater
than 7 is considered a base and any pH number less than 7 is considered an acid. 0 is the strongest
acid and 14 is the strongest base.
