Sample questions from Bio 210 Chapter 1 Organization of the Body Anthony's Textbook of Anatomy & Physiolo 22ND Edition Patton, Bell, Thompson, Williamson Lesson 1.1 1. Describe T

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

1. 1.Which statement correctly distinguishes anatomy from physiology?

   • A.Anatomy studies cells, whereas physiology studies only organ systems.
   • B.Anatomy explains body functions, whereas physiology describes body structures.
   • C.Anatomy describes body structures, whereas physiology explains how those structures function.
   • D.Anatomy and physiology both refer only to the study of body structures.

   Rationale: Anatomy focuses on structures and their relationships, while physiology focuses on how those structures work. The second option reverses the definitions, and the third incorrectly treats the terms as synonyms. The fourth imposes a level-of-organization distinction that does not define either field.

2. 2.A histology student observes a group of similar cells working together to perform a shared function. Which level of organization is being observed?

   • A.Tissue
   • B.Organ system
   • C.Organ
   • D.Organism

   Rationale: A tissue is a group of similar cells and their surrounding material organized to perform a common function. An organ contains multiple tissue types, and an organ system contains multiple organs working together. An organism is the whole living individual.

3. 3.Which statements correctly describe levels of organization in the body? Select all that apply.

   • A.Chemical components can combine to form cells.
   • B.An organ contains at least two kinds of tissues working together.
   • C.Tissues are composed of groups of organs.
   • D.Organ systems are made up of organs that contribute to related functions.
   • E.The organism level is less complex than the cellular level.

   Rationale: Chemical components organize into cells, and organs contain multiple tissue types that work together. Organ systems comprise organs that contribute to related functions, so these three descriptions are correct. Tissues are made of cells rather than groups of organs, and the organism is the most complex level listed, not less complex than a cell.

4. 4.Which sequence lists levels of organization from least complex to most complex?

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

   Answer and rationale are in the full material.

5. 5.Which statements correctly describe how organ systems contribute to the whole body? Select all that apply.

   • A.The skeletal system produces digestive enzymes for nutrient absorption.
   • B.The urinary system helps remove wastes and regulate the composition of body fluids.
   • C.The digestive system distributes oxygen to body tissues.
   • D.The respiratory system exchanges gases between the body and the environment.
   • E.The nervous system helps coordinate and regulate body activities.
