BIOL 2113 Final Exam Review – Guided Study Notes for Anatomy & Physiology

Q1. Define anatomy and physiology. How are they related? What are the subdivisions of anatomy?

Background

Topic: Introduction to Anatomy & Physiology

This question tests your understanding of the basic definitions and relationships between anatomy and physiology, as well as the main branches of anatomical study.

Key Terms:

• Anatomy: The study of the structure of body parts and their relationships to one another.

• Physiology: The study of the function of the body and how its parts work together.

• Subdivisions of Anatomy: Includes gross (macroscopic), microscopic, and developmental anatomy, among others.

Step-by-Step Guidance

1. Start by writing clear definitions for both anatomy and physiology in your own words.

2. Explain how the structure of a body part (anatomy) relates to its function (physiology) with an example (e.g., how the shape of the heart enables it to pump blood).

3. List the main subdivisions of anatomy, such as gross anatomy (visible to the naked eye), microscopic anatomy (cells and tissues), and developmental anatomy (changes throughout life).

Q2. List and describe the 6 levels of structural organization in the human body.

Background

Topic: Levels of Organization

This question assesses your knowledge of the hierarchical organization of the human body, from the simplest to the most complex level.

Key Terms:

• Chemical level

• Cellular level

• Tissue level

• Organ level

• Organ system level

• Organismal level

Step-by-Step Guidance

1. List each level of organization in order from simplest to most complex.

2. For each level, write a brief description of what it includes (e.g., the chemical level includes atoms and molecules).

3. Provide an example for at least one level (e.g., muscle tissue at the tissue level).

Q3. List and describe the 8 necessary life functions.

Background

Topic: Necessary Life Functions

This question checks your understanding of the essential processes required for life in humans.

Key Terms:

• Maintaining boundaries

• Movement

• Responsiveness

• Digestion

• Metabolism

• Excretion

• Reproduction

• Growth

Step-by-Step Guidance

1. List all eight necessary life functions.

2. Write a brief description of each function (e.g., movement refers to activities promoted by the muscular system).

3. Think of an example for at least one function to help solidify your understanding.

Q4. What is homeostasis? Compare negative vs. positive feedback loops. What are variables?

Background

Topic: Homeostasis and Feedback Mechanisms

This question tests your understanding of how the body maintains internal stability and the mechanisms involved.

Key Terms:

• Homeostasis: The maintenance of a stable internal environment.

• Negative feedback: A mechanism that reverses a deviation from the set point.

• Positive feedback: A mechanism that amplifies a change.

• Variable: The factor or event being regulated (e.g., body temperature).

Step-by-Step Guidance

1. Define homeostasis in your own words.

2. Describe the difference between negative and positive feedback loops, including an example of each (e.g., body temperature regulation for negative feedback, blood clotting for positive feedback).

3. Explain what is meant by a variable in the context of homeostasis.

Q5. What is anatomical position?

Background

Topic: Anatomical Terminology

This question checks your understanding of the standard reference position used in anatomy to describe locations and directions on the human body.

Key Terms:

• Anatomical position: The standard body position used as a reference in anatomy.

Step-by-Step Guidance

1. Describe the anatomical position, including the orientation of the body, head, arms, and feet.

2. Explain why this position is important for anatomical reference.

Q6. What organs are in the dorsal body cavity?

Background

Topic: Body Cavities

This question tests your knowledge of the major body cavities and the organs they contain.

Key Terms:

• Dorsal body cavity: The cavity located along the posterior (back) side of the body.

• Cranial cavity: Contains the brain.

• Vertebral (spinal) cavity: Contains the spinal cord.

Step-by-Step Guidance

1. Identify the two main subdivisions of the dorsal body cavity.

2. List the primary organ found in each subdivision.
