Purdue Global SC131: Human Anatomy and Physiology II
SC131 completes the anatomy and physiology sequence, covering the cardiovascular, respiratory, immune, digestive, urinary, and reproductive systems with a lab component. It assumes SC121's foundation and moves at the same compressed 10-week pace.

Build my SC131 study planWhat makes it hard
The systems in SC131 are more process-heavy than SC121's — cardiac cycles, gas exchange, filtration, hormonal regulation — so pure structure memorization stops being enough. Students have to explain how systems work and interact, and the ones who scraped through SC121 on cramming find the second course collects the debt.
What you'll cover
- • The cardiovascular system
- • The respiratory system
- • The immune system
- • The digestive system
- • The urinary system and fluid balance
- • The reproductive system
The SC131 study guide
How to study for Purdue Global SC131, step by step.
- 1
Patch SC121 gaps before week one
SC131 assumes cells, tissues, and terminology are automatic. Spend the break between courses reviewing your SC121 weak spots — the new systems build on that vocabulary without pausing.
- 2
Study processes as stories, not lists
Trace a drop of blood through the heart, a breath through gas exchange, a meal through digestion. SC131 grades whether you can explain sequences, and narrative beats memorized fragments for that.
- 3
Draw the flows from memory weekly
Sketch the cardiac cycle or nephron filtration on blank paper, then check against the text. Diagram recall is the strongest predictor of exam performance in process-heavy units.
- 4
Keep flashcards for structures, explanations for functions
The terms still need cards, but pair every structure with a why-it-matters sentence. Assessment questions increasingly ask what happens when a system fails, not just what it's called.
- 5
Connect systems to each other as you go
Cardiovascular meets respiratory at gas exchange, urinary meets endocrine at fluid balance. The integration questions are where strong students separate, and the connections are cheap to note in the moment.

How Fennie helps with SC131
Fennie's Daily Plans pace SC131's process-heavy systems so each one gets explanation practice, not just term review, before its assessment. Chat through a physiological sequence — the cardiac cycle, nephron filtration — until you can narrate it cold, and keep the structure vocabulary alive with generated flashcards and quizzes.
FAQ
Is SC131 harder than SC121?
Most students say yes — the systems are more process-driven, so understanding how things work matters as much as memorizing names. Students with a solid SC121 foundation find it a fair continuation; students who crammed through SC121 struggle early.
What does SC131 cover?
The second half of the body: cardiovascular, respiratory, immune, digestive, urinary, and reproductive systems, with lab exercises throughout, over Purdue Global's standard 10-week term.
How do I study for SC131 exams?
Practice explaining processes from memory — trace blood flow, gas exchange, and filtration on blank paper rather than rereading diagrams. Keep flashcards for structures, but expect questions about how systems work and interact.

SC121 — Human Anatomy and Physiology I
SC121 is the first half of Purdue Global's anatomy and physiology sequence, covering cells, tissues, homeostasis, and the early body systems — integumentary, skeletal, muscular, and nervous — with a lab component. It's a cornerstone requirement for health science and nursing-track students.
SC235 — General Biology I: Human Perspectives
SC235 is Purdue Global's general-education biology course, introducing life science through a human lens — cells, molecules, genetics, and organ systems, with everyday applications stressed throughout. For many non-science majors it's the lone lab science in their degree.
