BIOS 255 – Lab Practicum Review (50+ Questions) – Cardiovascular, Lymphatic & Respiratory Systems – Chamberlain University

This document is a complete lab practicum review for BIOS 255: Human Anatomy and Physiology III at Chamberlain University, designed for the 2025/2026 academic year. It contains over 50 structure-identification questions with verified correct answers, covering visual and practical components of the cardiovascular, lymphatic, and respiratory systems. The resource serves as an essential preparation tool for lab exams where students are expected to identify structures on models, charts, or microscopic slides. Covered systems and topics include: Cardiovascular system: identification of blood components (erythrocytes, leukocytes, neutrophils, etc.), heart valves (bicuspid, tricuspid, aortic, pulmonary), heart anatomy (chambers, layers, vessels), and major arteries and veins (e.g., brachiocephalic trunk, subclavian artery, inferior vena cava) Lymphatic system: major organs (thymus, spleen, tonsils, lymph nodes, red bone marrow), drainage systems (thoracic duct, right lymphatic duct, cisterna chyli), and immune structures like lacteals and pharyngeal regions Respiratory system: lung anatomy (lobes and fissures, hilum, carina), airway structures (pharynx, larynx, trachea, nasal conchae), and key microscopic features (alveolar cells, respiratory membrane, macrophages, surfactant-producing cells) Each term is clearly listed and marked as answered, simulating the kind of rapid recognition required during lab practical assessments. It is highly visual in structure and supports direct memorization of anatomical terms. Ideal for: Students enrolled in BIOS 255 or any lab-based A&P III course Nursing and pre-health program participants preparing for practical exams Learners needing structured, visual review of body systems for identification purposes This lab guide complements lecture materials and textbooks by focusing specifically on hands-on, exam-relevant identification, making it a critical companion for high-stakes lab testing.
