KN 231: Anatomy and Physiology Lecture II
About 3 hours 30 min on Lorea13 chapters1 school
Looking up KN 231 (Anatomy and Physiology Lecture II)? This is the 16-week anatomy and physiology course pre-nursing, pre-health, and biology students take before lab practicals and clinical follow-on courses.
At University of Illinois at Chicago, KN 231 is the code on the schedule, the textbook list, and the exam. This page follows Anatomy & Physiology 2e (OpenStax) chapter for chapter - 13 chapters over 16 weeks - and opens a free Lorea course with no signup.
If you are asking "is KN 231 hard?" start with the failure points below, then drill the 13 OpenStax chapters instead of rereading the PDF.
Lorea is independent and not affiliated with University of Illinois at Chicago.
What KN 231 covers
KN 231 covers Endocrine system, blood, heart, blood vessels and circulation, lymphatic and immune system, respiratory, digestive, metabolism and nutrition, urinary, fluid and acid-base balance, reproductive, development. The sequence matches Anatomy & Physiology 2e (OpenStax), the open textbook this page is built from - 13 chapters across a 16-week semester, in the same order your lecture is likely to follow.
What makes KN 231 hard
Cardiac conduction sequence and the ECG trace; blood vessel pathways memorisation; nephron function and filtration/reabsorption direction; acid-base compensation (respiratory vs metabolic); endocrine axis feedback loops. Those are the spots students miss on timed KN 231 exams even after they "read the chapter." Drill them with retrieval - practice questions, blank figures, setup-only problem sets - not another highlight pass.

How to study for KN 231
1. Name the structures out loud
KN 231 punishes recognition-only study. Cardiac conduction sequence and the ECG trace; blood vessel pathways memorisation; nephron function and filtration/reabsorption direction; acid-base compensation (respiratory vs metabolic); endocrine axis feedback loops. Say the term, then point to it on a blank figure.
2. Use spaced lists for volume
Bone markings, cranial nerves, and vessel pathways are lists. Review them on day 1, 3, and 7 instead of cramming the night before lab.
3. Trace the direction of flow
For muscle, nerve, and kidney units, draw arrows: where does the signal / filtrate / blood go next? Direction errors are the usual exam trap.
4. Teach one pathway to a blank page
Pick the hardest loop from this week and write it with no notes. If you stall, that is the card to make - not a new highlight color.
5. Run a free practice block
Open the free Anatomy and Physiology Lecture II course on Lorea (no signup) and treat misses as a map of the 13 chapters, not a score.

FAQ
Is KN 231 hard?
Yes - KN 231 is a weeder for many students because of specific failure points, not because the textbook is obscure. Cardiac conduction sequence and the ECG trace; blood vessel pathways memorisation; nephron function and filtration/reabsorption direction; acid-base compensation (respiratory vs metabolic); endocrine axis feedback loops. Plan weekly retrieval around those, not a single reread of Anatomy & Physiology 2e (OpenStax).
How many chapters is KN 231?
KN 231 is 13 chapters in this guide, aligned to Anatomy & Physiology 2e (OpenStax): Ch 16 The Neurological Exam; Ch 17 The Endocrine System; Ch 18 The Cardiovascular System: Blood; Ch 19 The Cardiovascular System: The Heart; Ch 20 The Cardiovascular System: Blood Vessels and Circulation; Ch 21 The Lymphatic and Immune System; Ch 22 The Respiratory System; Ch 23 The Digestive System; Ch 24 Metabolism and Nutrition; Ch 25 The Urinary System; Ch 26 Fluid, Electrolyte, and Acid-Base Balance; Ch 27 The Reproductive System; Ch 28 Development and Inheritance.
What textbook does KN 231 use?
KN 231 in this guide follows Anatomy & Physiology 2e (OpenStax). Your section may assign a different commercial book; the chapter titles above are the OpenStax sequence used at the listed schools.
What is the difference between KN 231 and the next course in the sequence?
KN 231 is the second course in the sequence. It assumes you already have the first-semester map (cells, chemistry, or intro psych, depending on the department) and moves into systems, second-semester chemistry, or applied psychology. Confirm the prereq on your campus schedule - the code after this one is school-specific.
Which schools use the KN 231 code?
KN 231 is used at University of Illinois at Chicago. If your campus prints this exact code, the chapter list on this page is the one to study against.
Is KN 231 the same as the old KN 252 code?
KN 251 and KN 252 were UIC's combined lecture-plus-lab A&P courses through Spring 2024. Fall 2024 split them: KN 230 (lecture) and KN 232 (lab) replaced KN 251; KN 231 and KN 233 replaced KN 252. This page is the current lecture code.
Are there free KN 231 flashcards?
Yes. The free Lorea Anatomy and Physiology Lecture II course linked on this page covers all 13 Anatomy & Physiology 2e (OpenStax) chapters as retrieval practice — use it like KN 231 flashcards without signing up.
How do I prepare for the KN 231 lab practical?
KN 231 lab practicals usually test structure ID, muscle origins, and the systems covered in your first lab units. Name structures out loud, trace flow on blank diagrams, and match your lab manual to the chapter list above — then run the free Lorea practice block for the units your instructor schedules before practical week.
What is on KN 231 exam 1?
Exam 1 in KN 231 usually covers the first third of the term — often The Neurological Exam, The Endocrine System, The Cardiovascular System: Blood, and more depending on your syllabus. Match the chapter list above to your exam date; the free Lorea course lets you run retrieval on those units before the midterm.
