D313 Anatomy and Physiology II completes the human body systems coverage begun in D312. Our question bank aligns with the OA format, covering endocrine, cardiovascular, respiratory, digestive, urinary, and reproductive systems, plus fluid/electrolyte balance and immunity. Practice with our materials to master physiology and pass the exam.
D313 covers the second half of human anatomy and physiology. Our question bank mirrors the OA. Here's what our practice questions help you master:
Hormones, gland function, feedback loops, and regulation of metabolism, growth, and homeostasis.
Heart structure, blood flow, gas exchange, and the physiology of circulation and breathing.
Digestion, absorption, nutrient processing; kidney structure, filtration, and urine formation.
Reproductive anatomy and physiology; immune response, fluid/electrolyte balance.
Our question bank is designed to help you master the D313 OA with targeted practice and detailed explanations.
Questions match the D313 OA in format and difficulty, including systems integration and application scenarios.
Each answer includes clear explanations to reinforce physiology concepts and regulatory mechanisms.
All D313 content areas are covered—endocrine, cardiovascular, respiratory, digestive, urinary, reproductive, and more.
Build confidence with practice that familiarizes you with OA format and question styles.
We're committed to your success with comprehensive support and a pass guarantee.

D313 Anatomy and Physiology II completes the human body systems sequence. It covers endocrine regulation, cardiovascular and respiratory systems, digestion and metabolism, urinary function, reproduction, fluid/electrolyte balance, and immunity. The focus is on how systems work together to maintain homeostasis.
D313 builds directly on D312, so a solid foundation in cells, tissues, and the nervous and muscular systems is essential.
D313 emphasizes integration across systems. Questions often require you to understand how one system affects another—for example, how the endocrine system regulates cardiovascular function, or how respiratory and urinary systems work together in acid-base balance. The OA tests both isolated system knowledge and integrative thinking.
By the end of D313, you will have developed competencies including:
Anatomy and Physiology II covers a lot of material. Our D313 question bank helps you consolidate knowledge across all systems and prepares you for the integration-heavy OA. Use our questions and answers to identify gaps and build the confidence to pass.
