Sample questions from 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 orders the levels of structural organization from simplest to most complex?

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

   Rationale: Chemical components combine to form cells, the simplest living units. Similar cells form tissues, tissues form organs, and organs work together in organ systems within the organism. The other sequences reverse or misorder these relationships.

2. 2.Which statement best explains the relationship between structure and function in the body?

   • A.All structures perform the same function when they are part of one system.
   • B.Function can be understood without considering the structure involved.
   • C.A structure's function determines that it has no consistent form.
   • D.A structure's form supports the tasks it performs.

   Rationale: The form of a body part is closely related to the work it performs. For example, the shape and arrangement of cells can support a tissue's particular function. The other choices incorrectly separate structure from function or assume body parts are interchangeable.

3. 3.Which organ system includes the skin, hair, and nails and provides a protective external covering?

   • A.Urinary
   • B.Lymphatic
   • C.Integumentary
   • D.Endocrine

   Rationale: The integumentary system consists principally of the skin and its accessory structures, including hair and nails, and provides a protective covering. The endocrine system releases hormones, the lymphatic system contributes to fluid return and defense, and the urinary system forms and eliminates urine.

4. 4.During a community class, an instructor reviews the levels of organization. Which statements are accurate? Select all that apply.

   • A.An organ is made of at least two tissue types working together.
   • B.The chemical level is more complex than the cellular level.
   • C.An organism is less complex than an organ system.
   • D.Cells are the basic living units of the body.
   • E.An organ system is a group of organs that cooperate in related functions.
   • F.A tissue is a group of similar cells working together.

   Answer and rationale are in the full material.

5. 5.A student traces the movement of oxygen from the respiratory system into the blood and then to body cells. Which concept does this best illustrate?

   • A.Organ systems cooperate to support normal body function.
   • B.The respiratory system alone delivers oxygen to every cell.
   • C.Each organ system functions independently of all others.
   • D.The cellular level is more complex than the organ-system level.
