    Study Notes

    Organ Systems and Their Functions

    • Lymphatic system: combats disease, maintains tissue fluid balance, absorbs dietary fats from the digestive tract
    • Respiratory system: exchanges oxygen and carbon dioxide between the lungs and respiratory passages, regulates blood pH
    • Digestive system: performs mechanical and chemical processes of digestion, absorption of nutrients, elimination of wastes
    • Urinary system: removes waste products from the blood, regulates blood pH, ion balance, water balance
    • Serous membranes: have two types - visceral (in contact with organs) and parietal (in contact with cavity walls)

    Anatomy and Physiology

    • Anatomical study: making a section through an organ to observe its interior, examining the surface of a bone, viewing tissue through a microscope
    • Control system components: receptor (detects change), control center, effector (responds to change)
    • Negative feedback mechanism: regulates variables, such as body temperature, blood pressure

    Approaches to Studying Anatomy

    • Regional anatomy: studies anatomy by dividing the body into regions
    • Systemic anatomy: studies anatomy by focusing on systems, such as the digestive system
    • Surface anatomy: studies the external features of the body
    • Anatomical imaging: uses imaging techniques, such as X-rays, to study anatomy

    Importance of Studying Anatomy and Physiology

    • Understanding how the body works helps to understand how it maintains homeostasis
    • Studying anatomy and physiology helps to understand how the body responds to stimuli

    Differentiation and Development

    • Differentiation: a process where cells become specialized in structure and function
    • Involved in growth and development, but not in metabolism

    Homeostasis

    • Governed by the nervous and endocrine systems working together
    • Maintains a stable internal environment despite changes in the external environment
