Anatomy & Physiology
Understand HOW the body works — the structural and functional knowledge that underpins everything in nursing. Pick a body system and start reviewing.

Each guide covers the anatomy, physiology, and clinical connections most commonly tested on the LPN/LVN exit exam.
Cardiovascular System
Heart anatomy, chambers and valves, blood flow pathway, cardiac cycle, cardiac output, blood vessels, blood pressure regulation, coronary arteries, and fetal circulation.
Respiratory System
Upper and lower airways, alveoli and surfactant, mechanics of breathing, gas exchange, oxygen transport, V/Q matching, ABG interpretation, and respiratory regulation.
Renal & Urinary System
Kidney anatomy, the nephron, urine formation, RAAS, ADH and aldosterone, fluid & electrolyte balance, acid-base regulation, BUN/creatinine, and lower urinary tract.
Nervous System
CNS and PNS, brain anatomy, the 12 cranial nerves, spinal cord, autonomic nervous system, neurotransmitters, reflexes, GCS, ICP, and stroke assessment.
Endocrine System
The pituitary, thyroid, parathyroid, adrenal glands, and pancreas; hormones and negative feedback, the hypothalamic-pituitary axis, blood glucose regulation, and calcium balance.
Digestive System
The GI tract from mouth to anus, the stomach, small and large intestine, plus the liver, gallbladder, and pancreas; digestion, absorption, and key GI and liver labs.
Musculoskeletal System
Bones and the skeleton, joints and cartilage, skeletal muscle, bone remodeling and calcium balance, fracture healing, and movement.
Integumentary System
The skin's three layers, hair, nails, and glands, plus thermoregulation, vitamin D, wound healing, and pressure-injury staging.
Hematologic & Immune System
Blood components, red and white blood cells, clotting, the lymphatic system, and innate vs adaptive immunity, plus key CBC labs.
Reproductive System
Male and female reproductive anatomy, spermatogenesis and oogenesis, the ovarian and menstrual cycles, the HPG axis, reproductive hormones, fertilization, and puberty & menopause.
Special Senses
The eye and vision, the ear and hearing, balance and equilibrium, plus smell and taste; rods and cones, the visual pathway, the Weber and Rinne tests, and PERRLA.
