Question 1
What is the difference between anatomy and physiology?
ANSWER
Anatomy is the study of the structure of body parts, whereas physiology is the study of the
function of body parts
Question 2
What are the levels of organization?
ANSWER
subatomic particles, atom, molecule, macromolecule, organelle, cell, tissue, organ, organ
system, organism
Question 3
What are the requirements of life?
ANSWER
Water, food, oxygen, heat, pressure
Question 4
What are the characteristics of life?
ANSWER
1
,Movement (internal or gross); Responsiveness (reaction to internal or external change);
Growth (increase in size without change in shape); Reproduction (new organisms or new
cells); Respiration (use of oxygen; removal of CO2); Digestion (breakdown of food);
Absorption (movement of substances through membranes and into fluids); Circulation
(movement within body fluids); Assimilation (changing nutrients into chemically different
forms); Excretion (removal of metabolic wastes)
Question 5
Define homeostasis
ANSWER
Body's maintenance of a stable environment
Question 6
What is a homeostatic mechanism?
ANSWER
the body maintains homeostasis through a number of self-regulating control systems;
examples are regulating body temperature and pressure sensitive receptors to regulate
body pressure
Question 7
Define matter
ANSWER
Anything that takes up space and has mass (weight). It is composed of elements.
Question 8
2
,Define element
ANSWER
fundamental substance composed of chemically identical atoms
Question 9
Define atoms
ANSWER
smallest particle of an element; basic unit of matter
Question 10
What is the structure of an atom?
ANSWER
An atom consists of a nucleus containing protons and neutrons, with electrons in
orbit around the nucleus.
Question 11
