Question 1
Explain the difference between the study of Anatomy and the study of Physiology
ANSWER
Anatomy is the study of structure of body parts/Physiology is the study of function of body
parts
Question 2
Name the levels of organization of life
ANSWER
Organelles, cells, tissues, organs, and organ systems
Question 3
Define Metabolisim
ANSWER
The sum of all physical and chemical events that obtain, release, and utilize energy
Question 4
Define Homeostasis. How does a homeostatic mechanism maintain homeostasis?
ANSWER
The body's maintenance of a stable internal environment.
1
,Depend on normal concentrations of water, nutrients, and oxygen, and normal body
temperature and pressure
Question 5
What is meant by negative feedback? How does negative feedback affect homeostatic
mechanisms?
ANSWER
Works to correct a deviation from a set point (Tries to get back to the set point/normal)
Question 6
Describe the structure of a serous membrane
ANSWER
Smooth membrane consisting of 2 layers of epithelial cells which secrete serous fluid
Question 7
What are signs of aging at the cellular level?
ANSWER
Impaired cell division and the ability to break down and recycle worn cell parts
Question 8
What is meant by anatomical position?
ANSWER
2
,Universal body position: Standing erect, facing forward, upper limbs at the sides, palms
facing forward and thumbs out.
Question 9
Explain why chemistry is an important part of the study of Physiology
ANSWER
Body functions depend on cellular functions that, in turn, result from chemical changes
Question 10
Atom
ANSWER
The smallest unit of matter that defines the chemical elements
Question 11
Element
ANSWER
Fundamental substances in which all matter is composed of
Question 12
Molecule
ANSWER
2 or more atoms may combine to form a molecule
3
, Question 13
Compound
ANSWER

Question 14
Name the bulk elements of the body
ANSWER
Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur, and Phosphorus
Question 15
What do atomic number and atomic weight of an atom represent?
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
Question 16
Define Ion. How do we indicate in a molecular formula if an atom is an ion?
ANSWER
Ions are atoms that gain or lose electrons and become electrically charged
