Biology II (GBIO150) Final & Midterm Exam Review – Step-by-Step Study Guidance

Q1. What is anatomy? What is physiology?

Background

Topic: Introduction to Anatomy and Physiology

This question tests your understanding of the basic definitions and distinctions between the two foundational sciences of the human body.

Key Terms

• Anatomy: The study of the structure and shape of the body and its parts.

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

Step-by-Step Guidance

1. Start by defining anatomy in your own words, focusing on what it studies (structure, form, organization).

2. Next, define physiology, emphasizing its focus on function and processes.

3. Think about examples: For anatomy, consider naming a body part and describing its structure; for physiology, describe what that part does.

Try answering these definitions before checking the answer!

Q2. What is the relationship between anatomy and physiology?

Background

Topic: Integration of Structure and Function

This question asks you to connect how the structure of body parts (anatomy) relates to their function (physiology).

Key Concept

• "Structure determines function" is a key principle in biology.

Step-by-Step Guidance

1. Reflect on how the shape or structure of a body part enables it to perform its function.

2. Think of a specific example (e.g., how the structure of the heart allows it to pump blood).

3. Summarize the general principle that links anatomy and physiology.

Try to explain the relationship in your own words before checking the answer!

Q3. What are the levels of structural organization in the body?

Background

Topic: Hierarchy of Biological Organization

This question tests your knowledge of the different levels, from smallest to largest, that make up the human body.

Key Terms

• Chemical level

• Cellular level

• Tissue level

• Organ level

• Organ system level

• Organismal level

Step-by-Step Guidance

1. List the levels in order from smallest (atoms/molecules) to largest (organism).

2. Briefly describe what each level represents.

3. Think of an example for each level (e.g., muscle cell, muscle tissue, heart, cardiovascular system, human body).

Try to write out the levels and examples before checking the answer!

Q4. What are the different organ systems of the body and what do they do?

Background

Topic: Human Organ Systems

This question requires you to recall the major organ systems and their primary functions.

Key Terms

• Examples: Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive

Step-by-Step Guidance

1. List each organ system by name.

2. For each, write a brief description of its main function.

3. Try to recall at least one major organ in each system.

Try to list and describe each system before checking the answer!

Q5. What are the necessary life functions?

Background

Topic: Characteristics of Life

This question asks you to identify the essential processes that define living organisms.

Key Terms

• Examples: Maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, growth

Step-by-Step Guidance

1. List the main life functions required for survival.

2. Briefly define each function in your own words.

3. Think of an example of each function in the human body.

Try to recall and define each function before checking the answer!

Q6. What are the body’s survival needs?

Background

Topic: Basic Human Needs

This question tests your knowledge of the environmental factors required for human survival.

Key Terms

• Nutrients, oxygen, water, normal body temperature, appropriate atmospheric pressure

Step-by-Step Guidance

1. List the five basic survival needs.

2. Briefly explain why each is important for the body.

Try to list and explain each need before checking the answer!

Q7. What is homeostasis?

Background

Topic: Homeostasis and Feedback Mechanisms

This question asks you to define homeostasis and understand its importance in physiology.

Key Terms

• Homeostasis: The maintenance of a stable internal environment

Step-by-Step Guidance

1. Define homeostasis in your own words.

2. Think of an example of a physiological variable that is regulated (e.g., body temperature).

3. Consider why maintaining homeostasis is important for health.

Try to define and give an example before checking the answer!

Q8. How does a negative feedback loop work? What are the components of a negative feedback loop? What is the difference between negative and positive feedback loops?

Background

Topic: Feedback Mechanisms in Physiology

This question tests your understanding of how the body maintains homeostasis through feedback loops.

Key Terms

• Negative feedback: A process that reduces or shuts off the original stimulus

• Positive feedback: A process that enhances or amplifies the original stimulus

• Components: Receptor, control center, effector

Step-by-Step Guidance

1. Describe the general steps of a negative feedback loop (stimulus, receptor, control center, effector, response).

2. List and define each component.

3. Compare negative and positive feedback with examples (e.g., body temperature vs. blood clotting).

Try to outline the steps and differences before checking the answer!

Q9. Know the language of anatomy: positional, directional and regional terms.

Background

Topic: Anatomical Terminology

This question tests your familiarity with the terms used to describe locations and directions in the body.

Key Terms

• Examples: Superior/inferior, anterior/posterior, medial/lateral, proximal/distal, superficial/deep

Step-by-Step Guidance

1. List the main positional and directional terms.

2. Define each term and give an example of its use.

3. Identify regional terms for different body areas (e.g., brachial, femoral).

Try to define and use each term before checking the answer!
