Sample questions from Naxlex Nursing Test Bank Bio 210 Chapter 1 Organization of the Body Anthony's Textbook of Anatomy & Physiology, 22ND Edition Patton, Bell, Thompson, Williamson

This material has 90 questions with answers and rationales. Here are the first 5.

1. 1.Which sequence correctly lists the levels of structural organization from simplest to most complex?

   • A.Chemical, cellular, tissue, organ, organ system, organism
   • B.Chemical, tissue, cellular, organ, organism, organ system
   • C.Organism, organ system, organ, tissue, cellular, chemical
   • D.Cellular, chemical, tissue, organ system, organ, organism

   Rationale: Chemical components combine to form cells, the basic structural and functional units of life. Similar cells form tissues, tissues form organs, and organs work together in organ systems that support the organism. The other sequences reverse or misplace levels, especially by putting tissues before cells or organ systems before organs.

2. 2.A biology student is reviewing the structural organization of the body. Which statements are accurate? Select all that apply.

   • A.An organ consists of at least two tissue types working together.
   • B.A tissue is a group of similar cells working together for a common function.
   • C.An organ system is a group of cells that all have an identical structure.
   • D.Cells are the basic structural and functional units of the body.
   • E.The organism level includes the functioning whole human being.

   Rationale: Cells are the body's basic structural and functional units, and similar cells form tissues that perform shared functions. Organs contain multiple tissue types that cooperate, while the organism level represents the whole living person. An organ system consists of multiple organs, not simply identical cells.

3. 3.Which organ system includes the heart and blood vessels and primarily transports substances throughout the body?

   • A.Endocrine system
   • B.Cardiovascular system
   • C.Urinary system
   • D.Respiratory system

   Rationale: The cardiovascular system circulates blood, transporting oxygen, nutrients, hormones, and wastes. The respiratory system exchanges gases, the urinary system removes wastes and helps regulate fluid balance, and the endocrine system secretes hormones. These systems interact, but transport through the blood is the cardiovascular system's primary role.

4. 4.Which example best illustrates the relationship between structure and function?

   • A.The long shape of a tendon allows it to produce hormones.
   • B.The thick epidermis allows rapid exchange of gases with the environment.
   • C.The thin walls of alveoli allow gases to diffuse efficiently.
   • D.The rigid bones of the skull allow it to expand freely during movement.

   Answer and rationale are in the full material.

5. 5.A person's body temperature rises above its regulated range. Which sequence best represents a negative-feedback response?

   • A.Receptors detect the change, effectors process it, and the control center produces the response.
   • B.The control center detects the change, effectors transmit information, and receptors restore the temperature.
   • C.Effectors detect the change, receptors produce a response, and the control center amplifies it.
   • D.Receptors detect the change, a control center processes it, and effectors produce responses that reduce the change.
