WGU C875: Human Anatomy and Physiology

What C875 Is and Why It Anchors Your Health Program

WGU C875, Human Anatomy and Physiology, introduces you to how the human body is built and how its systems keep you alive and functioning. Officially, the course surveys the structures and functions of the body's organs and systems and explores how those systems work together to produce movement, transport nutrients, eliminate wastes, protect vital tissues, regulate internal balance, and support reproduction and growth. You learn through short videos, readings, exploratory activities, and practice questions rather than a traditional lecture, so a lot of the pace is in your hands.

Direct answer: To pass C875, treat it as a memory-plus-understanding course: study the body one system at a time, use flashcards and repeated low-stakes quizzing to lock in terminology, and take the WGU pre-assessment until you consistently clear it before you schedule the proctored objective assessment.

C875 sits inside the Leavitt School of Health and appears across health-focused programs such as public health, health and human services, health information management, and psychology tracks. It is a foundational science course, which means later coursework and, for many students, real workplace conversations with clinicians assume you already speak this vocabulary. Note that C875 is a legacy course code; WGU has offered comparable Fundamentals of Anatomy and Physiology content under newer codes (for example, D203), so confirm the exact code and current course materials in your own degree plan and student portal before you start.

What the C875 Objective Assessment Covers

C875 is assessed by a proctored objective assessment (OA) rather than a written paper, so your job is to recognize and apply concepts across every major body system. While WGU can adjust its course materials over time, the anatomy and physiology content in this course consistently spans the following areas:

• Foundations and organization: levels of body organization, homeostasis, anatomical directional terms, body planes, and cavities.
• Chemistry and cell basics: the chemical building blocks of the body, cell structure, and how tissues are classified.
• Integumentary system: skin, hair, and nails and their protective roles.
• Skeletal and muscular systems: bones, joints, muscle types, and how muscles contract to produce movement.
• Nervous and endocrine systems: neurons and signaling, the brain and spinal cord, the senses, and hormone regulation.
• Cardiovascular and lymphatic/immune systems: the heart, blood, blood vessels, and how the body defends itself.
• Respiratory and digestive systems: gas exchange, nutrient breakdown, and absorption.
• Urinary and reproductive systems: fluid and waste balance and the structures that support reproduction and growth.

Notice the recurring theme: structure paired with function. The OA rewards students who can explain not just what a part is called but what it does and how it connects to neighboring systems.

How Hard Is C875, Really?

The difficulty of C875 is less about complex reasoning and more about sheer volume. Many students report that the terminology load is the hardest part, because you are learning hundreds of new words alongside the processes attached to them. If you have taken a biology or health science course before, much of this will feel like review with more depth. If this is your first serious science course in a while, expect it to demand steady, consistent effort.

Realistic prep time varies widely with your background. Students with recent science coursework sometimes move through it in a few weeks of focused study, while those starting fresh often plan for several weeks of daily review. Rather than chasing someone else's timeline, use WGU's pre-assessment as your gauge: when you can pass it comfortably and repeatedly, you are close to ready. Because C875 is self-paced, protecting a regular study block most days tends to work far better than occasional long cram sessions, which do not hold up well against a memory-heavy exam.

A Study Plan Built for Body Systems

The structure of C875 practically dictates the best way to study it: go system by system instead of trying to absorb everything at once. Here is a practical rhythm that fits how the brain retains anatomy and physiology.

• Work one system per study session. Read or watch the material for, say, the muscular system, then immediately summarize its major structures and their functions in your own words before moving on. This turns passive reading into active recall.
• Build and reuse flashcards. Terminology responds extremely well to spaced repetition. Make a deck for each system and revisit older decks on a rotating schedule so earlier systems do not fade while you learn new ones. Tools like the WGU learning resources and student-made flashcard sets are useful, but writing your own cards is where much of the learning happens.
• Draw and label. Sketching a rough heart, nephron, or neuron and labeling it from memory forces you to connect names to locations far better than rereading a diagram.
• Test yourself often. Use the practice questions in the course and take the official pre-assessment as a genuine dress rehearsal. Treat every missed question as a signpost pointing to the exact topic that needs another pass.
• Connect systems, do not silo them. Because the OA asks how systems work together, deliberately link topics: how the respiratory and cardiovascular systems cooperate to deliver oxygen, or how the nervous and endocrine systems both regulate the body at different speeds.

If you enjoy the physiology side of health science, you may find related coursework flows more easily afterward. Guides like D588 Human Sexuality and D517 Population Healthcare Coordination build on the body-systems literacy C875 gives you.

Mistakes That Trip Up C875 Students

A few predictable missteps cost students more time than the material itself:

• Memorizing names without functions. Recognizing that the "sinoatrial node" exists is not enough; the OA wants to know what it does. Always pair every structure with its job.
• Cramming a memory-heavy subject. Anatomy vocabulary decays quickly without repetition. Short daily reviews beat marathon weekend sessions.
• Skipping the pre-assessment or gaming it. Some students take the pre-assessment once, memorize its specific items, and assume they are ready. Use it to diagnose weak systems instead, then restudy those areas.
• Ignoring the "big picture" integration. Studying each system in isolation leaves you unprepared for questions about how systems interact, which is a core theme of the course.
• Leaning only on outside dumps and shortcuts. Random third-party answer sets can be outdated or simply wrong for the current course. Anchor your prep to WGU's own materials and verify anything else against them.

C875 Readiness Checklist

Before you schedule the proctored OA, run through these self-checks honestly:

• Can you use anatomical directional terms and body planes correctly to describe a location?
• Can you name the major organs of each body system and state the main function of each?
• Can you explain how a muscle contracts and how a nerve signal travels?
• Can you trace the path of blood through the heart and describe gas exchange in the lungs?
• Can you describe how the digestive system breaks down and absorbs nutrients?
• Can you explain how at least two systems cooperate, such as cardiovascular and respiratory, or nervous and endocrine?
• Can you pass the WGU pre-assessment comfortably and repeatedly, not just once?
• Can you recall key terminology from earlier systems without re-reading, days after you first studied them?

C875 FAQ

Is C875 assessed by an OA or a PA?

C875 is assessed by a proctored objective assessment (OA). It is a knowledge-based exam covering anatomy and physiology across all major body systems, rather than a submitted performance task or paper.

How many competency units is C875 worth?

C875 is a legacy course code, and its competency-unit value is not something we can verify from a current public WGU source, so check your official degree plan for the exact figure. Focus your energy on the material and the pre-assessment rather than the unit count.

Does C875 have a lab component?

This anatomy and physiology course is built around videos, readings, and practice activities and is measured by the objective assessment. It is distinct from WGU's separate A&P courses that carry a hands-on lab and a performance component, so confirm which version your program requires.

How long should I plan to study for C875?

It depends heavily on your science background. Students with recent coursework may need only a few weeks, while others plan for several weeks of daily study. The most reliable signal is passing the pre-assessment consistently, so let that guide your test date instead of a fixed calendar.

What resources work best for C875?

Start with WGU's own course materials and pre-assessment, then reinforce terminology with flashcards and spaced repetition. Labeling diagrams from memory and short reputable video explanations of individual systems can help, but always verify outside material against the course content.
