1. Introduction to Anatomy & Physiology

Given the following 5 levels of organization, which represents the correct hierarchy from smallest to largest?

A) TissueB) OrganC) MoleculeD) CellE) Organism

Which statement about the levels of organization in anatomy and physiology is most correct.

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?

Which of the following best describes the position of a tissue in the levels of organization of the human body?

a. Tissues are the most fundamental level of organization.

b. Tissues are between cells and organs in the levels of organization.

c. Tissues are the most complex level of organization.

d. Tissues are between organs and systems in the levels of organization.

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

Groups of many cells working together to perform a common function are known as a(n):

a. Cell

b. Organ

c. Organ system

d. Tissue

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.

Construct a table that lists the 11 systems of the body, names two organs of each system (if appropriate), and describes the overall or major function of each system.

a. Make a diagram showing the nine abdominopelvic regions, and name each region. Name two organs (or parts of organs) that could be located in each of the named regions.

b. Make a similar sketch illustrating how the abdominopelvic cavity may be divided into quadrants, and name each quadrant.

Which level of organization consists of groups of cells with similar structures and functions? (More than one may apply.)

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

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
