Unit 1493: Comprehensive Anatomy and Physiology for Paramedics

1. Introduction to Anatomy and Physiology

• Definition and scope of anatomy and physiology
• Key terminology: anatomical position, directional terms, planes, and body cavities
• Levels of body organization: cells, tissues, organs, and systems
• Importance of anatomy and physiology for paramedics

2. Body Systems Overview

• Overview of major body systems
  • Cardiovascular
  • Respiratory
  • Nervous
  • Musculoskeletal
  • Endocrine
  • Integumentary
  • Digestive
  • Renal
• Concept of homeostasis and feedback mechanisms
• Interrelationship between body systems

3. Cardiovascular System

• Anatomy of the heart: chambers, valves, and conduction system
• Blood vessels: arteries, veins, and capillaries
• Blood components: red blood cells, white blood cells, platelets, plasma
• Circulatory pathways: systemic and pulmonary circulation
• Regulation of blood pressure and cardiac output
• Transport of oxygen, nutrients, and waste products
• Common cardiovascular emergencies and paramedic considerations

4. Respiratory System

• Anatomy of the respiratory tract: nasal cavity, pharynx, larynx, trachea, bronchi, lungs, alveoli
• Mechanics of breathing: inspiration and expiration
• Gas exchange process in alveoli
• Respiratory control centers and regulation of breathing
• Role in acid-base balance
• Assessment of respiratory function and common emergencies (e.g., airway obstruction, respiratory distress)

5. Nervous System

• Structure of the central nervous system: brain and spinal cord
• Peripheral nervous system: somatic and autonomic divisions
• Neurons: structure and function
• Neurotransmitters and synaptic transmission
• Sensory input and motor output coordination
• Nervous system role in emergency response and reflexes
• Common neurological emergencies

6. Musculoskeletal System

• Bone structure and types
• Muscle types: skeletal, smooth, cardiac
• Joint types and functions
• Role in movement, support, and protection
• Common musculoskeletal injuries encountered by paramedics (fractures, dislocations, sprains)
• Assessment techniques and emergency management

7. Endocrine System

• Major endocrine glands and their locations
• Hormones: types and mechanisms of action
• Regulation of metabolism, growth, and stress response
• Interaction with other body systems
• Endocrine emergencies (e.g., diabetic emergencies, adrenal crises)

8. Integumentary System

• Structure and layers of the skin
• Hair and nails anatomy
• Protective functions of the skin
• Role in temperature regulation and sensation
• Assessment of skin conditions and injuries (burns, wounds, infections)
• Emergency care considerations

9. Digestive System

• Anatomy of digestive organs: mouth, esophagus, stomach, intestines, liver, pancreas, gallbladder
• Processes: ingestion, digestion, absorption, elimination
• Nutrient metabolism basics
• Common gastrointestinal emergencies (e.g., bleeding, obstruction, poisoning)
• Assessment and management strategies for paramedics

10. Renal System

• Anatomy of kidneys, ureters, bladder, and urethra
• Physiology of urine formation and excretion
• Fluid and electrolyte balance
• Acid-base regulation
• Assessment of renal function and recognition of renal emergencies
• Paramedic interventions related to renal system
