68W Combat Medic Module 1 Anatomy and Physiology 2026 Study Guide | 350+ Army EMT Exam Questions and Answers on Anatomy, Physiology, Shock, Cardiovascular System, Respiratory System & Patient Assessment | 68W AIT Certification

This 68W Combat Medic Module 1 Anatomy and Physiology 2026 Study Guide contains more than 350 comprehensive Army EMT and Combat Medic exam questions with verified answers covering anatomy and physiology, medical terminology, respiratory anatomy, cardiovascular physiology, shock recognition, nervous system function, musculoskeletal anatomy, endocrine regulation, cellular metabolism, blood circulation, patient positioning, and emergency medical assessment principles. The document provides detailed review material on body systems, anatomical terminology, planes and directional terms, respiratory mechanics, cardiac output, blood pressure regulation, oxygen transport, perfusion, fluid compartments, and shock pathophysiology commonly tested during Army 68W Advanced Individual Training (AIT), EMT certification courses, National Registry preparation, and military medical training programs. The study guide is organized in a structured question-and-answer format specifically designed to strengthen foundational medical knowledge, anatomy comprehension, physiology competency, patient assessment skills, and military medical exam preparation. Students and combat medics will review major concepts including anatomical position, body planes, abdominal quadrants, proximal and distal relationships, musculoskeletal structures, spinal anatomy, respiratory physiology, gas exchange, cardiovascular circulation, nervous system regulation, homeostasis, endocrine function, cellular metabolism, and emergency patient positioning. The material also explores critical EMT concepts such as dyspnea, tachypnea, bradypnea, apnea, hypoventilation, perfusion, oxygenation, minute volume, tidal volume, ventilation-perfusion matching, and shock recognition. Major topics covered throughout the document include cervical, thoracic, lumbar, sacral, and coccygeal vertebrae; upper and lower extremity anatomy; pelvis and acetabulum structures; respiratory structures including the nasopharynx, oropharynx, larynx, trachea, bronchi, alveoli, diaphragm, and intercostal muscles; cardiovascular anatomy including the myocardium, atria, ventricles, aorta, coronary arteries, and major pulse points; and neurological structures involving the central nervous system, peripheral nervous system, autonomic nervous system, hypothalamus, and medulla oblongata. The guide also reviews blood components, cardiac output, stroke volume, preload, afterload, contractility, blood pressure regulation, capillary exchange, hydrostatic pressure, plasma oncotic pressure, and oxygen delivery mechanisms. Additional sections focus extensively on shock physiology and emergency medicine concepts, including hypovolemic shock, distributive shock, cardiogenic shock, obstructive shock, loss of vascular tone, excessive capillary permeability, blood volume regulation, sympathetic nervous system responses, compensation mechanisms, and clinical shock indicators such as tachycardia, tachypnea, delayed capillary refill, altered mental status, diaphoresis, and pale skin. The document further reinforces essential combat medic knowledge involving fluid compartments, intracellular and intravascular fluid balance, cellular energy production (ATP), aerobic and anaerobic metabolism, electrolyte regulation, and trauma-related disruptions to respiratory and cardiovascular function. This resource is especially valuable for Army 68W Combat Medic candidates, EMT students, Advanced EMT students, military healthcare trainees, National Registry EMT candidates, emergency medical responders, nursing students, physician assistant students, military medical personnel, and individuals preparing for combat medic certification examinations or emergency medical careers. It is highly suitable for Army AIT preparation, NREMT review, EMT coursework, military medical education, anatomy and physiology courses, patient assessment training, and independent healthcare study. The anatomy, physiology, and emergency medical concepts discussed throughout this review align with widely recognized EMS and medical education literature, including: Emergency Care and Transportation of the Sick and Injured by the American Academy of Orthopaedic Surgeons (AAOS) Nancy Caroline’s Emergency Care in the Streets by Nancy Caroline Principles of Anatomy and Physiology by Gerard J. Tortora and Bryan Derrickson Combat Medic Specialist (68W) Training Program published by the U.S. Army Medical Center of Excellence Core topics such as anatomy and physiology, shock management, respiratory function, cardiovascular physiology, nervous system regulation, patient assessment, perfusion, oxygenation, cellular metabolism, and emergency medical care are also supported by standards and educational guidance published by NREMT, NAEMT, AHA, American Red Cross, and the U.S. Army Medical Department.
