APHY 101 - Midterm Ch. 1-6 exam 2023/ 123
Questions and Answers/ verified/100%
Correct.
Explain the difference between the study of Anatomy and the study of Physiology - -
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 - -Organelles, cells, tissues, organs,
and organ systems
-Define Metabolisim - -The sum of all physical and chemical events that obtain, release,
and utilize energy
-Define Homeostasis. How does a homeostatic mechanism maintain homeostasis? - -
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? - -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 - -Smooth membrane consisting of 2
layers of epithelial cells which secrete serous fluid
-What are signs of aging at the cellular level? - -Impaired cell division and the ability to
break down and recycle worn cell parts
, -What is meant by anatomical position? - -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 - -Body
functions depend on cellular functions that, in turn, result from chemical changes
-Atom - -The smallest unit of matter that defines the chemical elements
-Element - -Fundamental substances in which all matter is composed of
-Molecule - -2 or more atoms may combine to form a molecule
-Compound - -A substance made from two or more elements chemically combined
-Name the bulk elements of the body - -Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur,
and Phosphorus
-What do atomic number and atomic weight of an atom represent? - -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? - -Ions are
atoms that gain or lose electrons and become electrically charged
-Isotope - -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 - -
-Electrolyte - -An electrolyte is a substance that produces an electrically conducting
solution when dissolved in water.
