1. Introduction to Anatomy & Physiology

The following is a list of six levels of organization that make up the human body:

(1) Tissue

(2) Cell

(3) Organ

(4) Chemical

(5) Organism

(6) Organ system

The correct order, from the simplest to the most complex level, is

(a) 2, 4, 1, 3, 6, 5

(b) 4, 2, 1, 3, 6, 5

(c) 4, 2, 1, 6, 3, 5

(d) 4, 2, 3, 1, 6, 5

(e) 2, 1, 4, 3, 5, 6

The correct sequence of levels forming the structural hierarchy is:

a. Organ, organ system, cellular, chemical, tissue, organismal

b. Chemical, cellular, tissue, organismal, organ, organ system

c. Chemical, cellular, tissue, organ, organ system, organismal

d. Organismal, organ system, organ, tissue, cellular, chemical

During a cancer screening a doctor may choose to screen using histological or cytological methods. Cytological methods are often less invasive than histological methods. Why do you think this may be?

Collections of specialized cells and cell products that perform a relatively limited number of functions are called

(a) Cellular aggregates,

(b) Tissues

(c) Organs

(d) Organ systems

(e) Organisms

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

All living organisms are composed of one or more cells.
