This document is a focused review guide for BIOS 255: Human Anatomy and Physiology III at Chamberlain University, tailored specifically for Exam 2 preparation in the 2025/2026 academic year. It includes over 40 fully solved and clearly labeled questions, targeting key exam-relevant topics in cardiovascular anatomy, hemodynamics, venous/arterial circulation, and immune/lymphatic systems. Key areas covered include: Vascular system and circulation: classes of arteries (elastic, muscular, arterioles), pulse points, layers of blood vessels, branches of the aortic arch, and the hepatic portal system Venous drainage and flow: including pathways through the internal jugular, inferior and superior vena cava, azygos system, and brain/thoracic drainage Blood pressure and regulation: MAP calculation, cardiac output, venous return, vascular resistance, and colloid osmotic pressure Lymphatic and immune systems: lymphatic drainage by thoracic and right lymphatic ducts, MALT, lymph vs. interstitial fluid, primary and secondary immune organs (bone marrow, thymus, spleen, tonsils), and cancer metastasis pathways This document is especially useful for: Students preparing for BIOS 255 midterm or unit exams covering cardiovascular and immune systems Pre-nursing, pre-med, or allied health students reviewing for detailed multiple-choice exams Learners looking for a structured and direct Q&A format for quick reinforcement and memorization The content supports conceptual understanding and clinical relevance (e.g., cancer metastasis routes, MAP formulas), making it a well-rounded, exam-focused resource.
